Layer C and Layer T Take Center Stage at WDM 2015


By Geoff Bennett, Director, Solutions and Technology

The show I will always think of as “WDM”, but which now rejoices in the snappy title of “WDM and Next Generation Optical Networking” took place last week in Nice, France.

Last week, all the things you’d expect were there – sun drenched Mediterranean beaches, superb French cuisine…and a major taxi driver strike in protest against Uber! It wouldn’t be France without at least one national strike that causes chaos for the conference attendees. Check out this graphic!

Another thing that was no surprise was the focus of the first day of the event – the increasing demands of a Cloud Services Layer (Layer C) driving the need for scalability, flexibility and programmability in the underlying transport network (Layer T). These dynamics are well described in the Day One Sessions in which I took part.

Layer C & Layer T

Layer C & Layer T

We heard from Andrew Schmitt of IHS on the growth of capacity in agreement with his predictions of the Long Haul Optical Reboot, and that this trend towards 100G is already taking off in the metro.

Amongst the other presentations in the morning we heard how BT and TeliaSonera International Carrier have been taking advantage of coherent technologies to increase fiber capacity.

Three Axes of Fiber Scaling.  The red dot indicates today’s single wavelength transponder “state of the shelf” – a 32GBaud signaling rate, using PM-QPSK modulation.

Three Axes of Fiber Scaling. The red dot indicates today’s single wavelength transponder “state of the shelf” – a 32GBaud signaling rate, using PM-QPSK modulation.

In particular, Kevin Smith of BT outlined three axes of capacity scaling – the first axis is increasing the Baud rate of individual wavelengths, although this is an axis that is severely limited by the performance of today’s opto-electronics. The second axis is increasing the number of bits carried by each symbol, in other words the move to higher order modulation such as 8QAM and 16QAM. We have several blogs (The 8QAM Sweet Spot, Fire Up The Flux Capacity and Crank It Up To Terabit Scale, Infinera’s Expanding FlexCoherent Toolkit allows Subsea Operators to Maximize Fiber Capacity and Reach) on this topic on the Infinera site already, and there seems to be general acceptance that 16QAM will not be a universal solution for optical transmission over today’s fiber.

(As a side note, Ian Redpath of Ovum presented the results of his informal survey of conference attendees in which less than 50% of the respondents seem to be “sold” on 16QAM at the moment).

Kevin’s third axis is the move to super-channels and in his case, he presented the evolution of the conventional DWDM vendors who have to buy expensive optical components for single-wavelength implementations (even if multiple circuits are implemented on one line card). These approaches tend to exhaust the increase in Baud rate and modulation order first.

This is where Infinera’s mastery of large scale PIC technology makes a pivotal difference. Large scale (ie. multiple wavelengths on one chip) PICs make super-channels practical today – in a way that discrete optics (and pluggables) simply cannot. Since the first commercial super-channel shipments in 2012, PICs have given Infinera the ability to radically differentiate our solution.

This was the focus of my presentation, where I showed the commercial success of super-channels in the long haul and then posed the question – could they achieve the same success in metro? Ironically, the word “metro” in this context covers a lot of ground (i.e. the metro market is made up of multiple segments), and we have certainly seen the success of high capacity, super-channel solutions in one of these segments – the Data Center Interconnect market. Several speakers acknowledged that this is a market that has essentially been created by Infinera last year with our introduction of the Cloud Xpress, and is now being copied with several announced (but not yet shipping) products from other DWDM vendors.

Another, distinct segment of “metro” is metro aggregation. Here we tend to see high capacity hub sites that certainly will benefit from super-channel operational scalability (i.e. install the line card and forget about it), but these sites aggregate traffic from spoke sites that are probably prime candidates for a move to 100Gb/s connection speeds.

Sliceable Super-Channels

Sliceable Super-Channels

This is the application area targeted by Infinera’s “sliceable PIC” technology. Above you can see how this works. Our sliceable PIC is located in the hub site, and FlexROADM technology is used to slice its capacity out to multiple spoke sites. At these locations, we deploy the application-optimized 100G PIC (oPIC-100). Service providers can also use Instant Bandwidth™ to turn on new super-channel capacity without visiting that location. The only truck roll needed is to install the oPIC-100 units in the spoke sites.

The combination of these technologies delivers operational scalability, cash flow optimization, and bandwidth efficiency.

And “metro” is still a much wider market than these two segments. We have metro access and metro packet as distinct segments, as well as mobile backhaul and mobile fronthaul.

Those of you who have been following the news will be aware that Infinera has made a commercial offer to acquire the Swedish company, Transmode. Their product range aligns perfectly with the existing Infinera solution set, with just enough overlap to allow a seamless, end to end solution to address the whole of the metro, long haul and subsea markets.

It’s clear that, in order to thrive, Layer C has to be “fed” by a scalable, dynamic and efficient Layer T. PIC-based super-channels have already proven themselves to be the perfect Layer T technology in the long haul market. It turns out that the same kind of point to point super-channel is an ideal solution for a simple Data Center Interconnect applications too. But now the addition of sliceability allows us to deploy PIC technology that’s ideal for the metro aggregation segment.

So, all in all, I have to say this was the most interesting WDM-NGON conference I’ve attended for many years – and not just because of the taxi strike!

Infinera’s Cloud Xpress Wins “Best of Show” Award at Interop 2015

MargoBy Margo Westfall, Senior Manager, Corporate Marketing

Infinera’s Cloud Xpress continues to gain momentum – first as a Leading Lights Award finalist in the “Best New Product (Telecom)” category, then with the expansion of our CX Product Family (up to 100 GbE for high capacity data center interconnect) and now with the “Best of Show Award” at Interop 2015 in Tokyo, Japan.



Interop, one of the world’s leading independent technology conferences, is designed to inspire, inform and connect the world’s IT community. This year, Interop Japan had more than 132,000 attendees learning about the latest advancements in networking, virtualization, cloud, mobility and data centers.

We were thrilled to have Hideki Ameku, Sr. Systems Engineer, APAC Sales at Infinera, along with our channel partner Nissho Electronics Japan, provide live demonstrations of the Cloud Xpress, showing its simplicity, scale and ease of use, during the event.

Industry experts engaged in several rounds of stringent assessments and the judges were impressed, calling it “the next generation of WDM.” Nissho Electronics was awarded the 2015 Best of Show Award in the data center networking category for Infinera’s Cloud Xpress.

It was selected for its power efficiency at 1 W/Gb/s and Instant Bandwidth™ capability, enabling rapid deployment of bandwidth in 100 Gb/s (100G) increments without having to deploy any additional hardware.

The Cloud Xpress family of Metro Cloud platforms offers a complete solution – Hyper-Scale Density + Simplified Operations + Low Power– and is designed specifically to address the needs of Cloud service providers, Internet content providers, Internet Exchange service providers, large enterprises and other large-scale datacenter operators. We carved out this market in 2014 using input directly from customers, and are proud to be the only company shipping a compact rack-and-stack form factor:  1Tb/s of Input/Output in a short 2 RU (3.75”). We’ve seen strong interest from customers and have been shipping Cloud Xpress platforms since December 2014.

And, just last month, we announced the expansion of the Cloud Xpress family with a new Cloud Xpress platform that is designed to interconnect higher capacity 100 GbE client devices while expanding our feature set to include – including MACsec encryption, support for NETCONF & YANG, SDN protocols that enable automation and LLDP discovery protocols, that enable discovery of Ethernet Switches & Routers across the wide area network.


CX - front

The “Best of Show” award is not only a testament to our innovation, but also to our channel partnerships that help us drive mutual value (and mindshare) with our customers. We look forward to meeting (and exceeding) customer demands both directly and through our channels as we continue to advance the metro Cloud market.

Fiber Network Optimization: Get More from your Fiber with Multi-Carrier Optical Super-Channels – A Perspective from ANGA COM

Gaylord Hart, Director MSO Market Segment

By Gaylord Hart, Director MSO Market Segment

I recently attended the ANGA COM Exhibition and Congress in Cologne, Germany.  With 17,000+ participants from 74 countries, 450 exhibitors and 150 speakers, this conference continues to be a popular place for the international cable telecommunications community to learn and share business and technical challenges and solutions.

While there, I, along with other distinguished panelists, discussed various ways to improve the fiber plant, including access & core networks.   The focus of my presentation was on terabit super-channels and how these can be implemented flexibly and cost-effectively while increasing fiber spectral capacity.




Implementing a terabit super-channel with just one or two waves is challenging due to constraints on commercially available high-speed electronics that would be required to process 192 or 384 gigabaud speeds. Instead, the fastest time to market will likely use a multi-carrier approach.  If the constituent waves in the super-channel are based on 100G technology, implementing such super-channels is readily possible with existing technology.

However, there is a tradeoff here.  A 1.2 Tb/s super-channel, for example, would require 12 x 100G waves in the super-channel and represents a significant increase in component count and complexity, especially if implemented using discrete photonics.  Fortunately, modern photonic integration technology solves this problem.  Since a photonic integrated circuit (PIC) combines multiple discrete optical components as well as their optical interconnects on a single monolithic chip that is manufactured in a single cycle, most of the complexity and cost issues associated with multi-carrier super-channels goes away.  What you also end up with is better density and reliability, but less heat and lower power consumption.




But perhaps the greatest advantage to multi-carrier super-channels is the flexibility they offer.  By allowing each wave in the super-channel to be individually tuned and provisioned for modulation format, the 12 channel 1.2 Tb super-channel used in the above example could be configured as a single super-channel (1 x 1.2 Tb), three super-channels (3 x 400G), 12 individual channels or any combination of these.  This allows the individual super-channels or waves to be independently routed through the network, where bandwidth is needed most and provisioned for modulation format to optimize reach versus bandwidth as needed.

Three’s a Crowd (Funding) at Infinera – Employees’ Grassroots Efforts for Nepal Disaster Relief

Jessy Kirkwood, Sr. Manager, Internal Communications & Training

Jessy Kirkwood, Sr. Manager, Internal Communications & Training

By Jessamyn Kirkwood. Sr. Manager, Internal Communications & Training

How many Infinera employees does it take to change a situation and shine a light on a devastating catastrophe?


Three team members who were stirred into action at the news of the 7.8 and 7.3 magnitude earthquakes that shook the country of Nepal in April of this year.

Four years ago, Infinera’s Sunnyvale-based team member Bahram Nadimi heard about an effort to start up an orphanage in Nepal. “I thought to myself, you aren’t married yet, you don’t have any children, you should sponsor a child,” Bahram shares. Knowing that females more often struggle to gain access to education, Bahram selected a little girl to support through the organization NECO Nepal Children’s Orphanage. Over time, he became more and more involved with the charity and developed a friendship with the founder, Bishow Bhatta. As Bahram’s sponsored child grew up into a thriving young woman, he decided it was time to make a bigger impact by joining NECO’s board of directors. Since then, he has helped champion the education, development and care of 34 Nepalese orphans.

Bahram: “The earthquake devastated the orphanage, almost completely destroying the building. The children are now living in a cow shed on the property. Fortunately, they were all taken care of but they are still terrified of more tremors. Because we want to help these children grow up to become future leaders of Nepal, we’ve mobilized them to help others impacted by the disaster. They put on yellow vests and go out to find people they can lend a hand to.”


When Bahram heard that others at Infinera wanted to raise funds for those in need, he joined in the movement. He reached out to the Infinera Community Fund and partnered with the committee to get the word out. Together, they undertook a fundraising campaign that raised over $4400 for charities in Nepal in just ten days. Infinera matched these donations, multiplying our assistance to the region.

If you wish to support NECO Nepal Children’s Orphanage, donations are welcome. In addition, your unused PCs and tablets are powerful educational tools for these children.


On April 28, Infinera Bangalore’s HR Director Jaya Johnson reached out to the entire office with a request for supplies. She had her allotment of number two pencils and multicolored sticky notes; she was looking for was items of a different kind.

The images of the people climbing out from the rubble of the Nepal earthquake had moved her and her colleague Kirti Naidu. “The stories on the television were so disheartening. We decided that we needed to do something about it. An agency had put an ad in the newspaper stating what supplies were needed and that they had already arranged for an airlines to carry them over,” Jaya shares.

Jaya and Kirti placed boxes on all the floors of our India offices. Employees dropped in the provisions, which were later sorted and sent to a pick up location. The Bangalore office rallied and donated eight huge cartons of supplies including dry foods, blankets, boxed drinks and bottled water. Now, Jaya, Kirti and the team have a whole new set of images they can call to mind when they hear about the circumstances in Nepal—the items they collected bringing hope and encouragement to people in need.



“I am from Nepal and lived there until I finished undergrad. When the earthquake happened, I wasn’t able to go back and help so I needed to do something from here in Sunnyvale.” Infinera Engineer Avsar Dahal rounds out this altruistic group of three.

A teammate and friend reached out to Avsar shortly after the first earthquake to check in on his family and ask how he was doing. Then the second earthquake hit and it became clear that the country was in an extreme state of emergency, beyond anything it had experienced before. The co-workers decided that something needed to be done and quickly.

Rather than delay their efforts with extensive planning and approvals, they launched a 30 minute fundraiser within their department. They provided lunch and tea and just hoped for the best. Within that brief half-hour, they raised over $650. They were surprised at the response and especially grateful for the generosity of their team.

“My parents, brother and sister are all safe and sound. There is a lot of aid coming into the country but the challenge is to get it to the people who really need it because they are in remote villages and regions.” - Infinera Engineer Avsar Dahal

“My parents, brother and sister are all safe and sound. There is a lot of aid coming into the country but the challenge is to get it to the people who really need it because they are in remote villages and regions.” – Infinera Engineer Avsar Dahal


At Infinera, our efforts of sacrifice and giving don’t end up as front page news. They are small initiatives championed by everyday people who’ve never launched a non-profit or marched in a protest. Yet, they are people who are fighting to make a difference in a place where no one is asking where the help comes from—because they just need it to show up one way or another. Three may be considered a crowd, but a crowd of people willing to give of themselves is always welcomed company.

Riding the 100G Wave

Jay Gill, Principal Product Marketing Manager

Jay Gill, Principal Product Marketing Manager

By Jay Gill, Principal Product Marketing Manager at Infinera

With the launch of the Cloud Xpress family in 2014, Infinera created a new market for cloud-optimized, hyper-scale datacenter transport. From the beginning, we said that Cloud Xpress would support customers needing to interconnect datacenters with 10 Gigabit Ethernet (GbE), 40 GbE and 100 GbE. Last week, we made good on the promise, announcing the newest Cloud Xpress with 100 GbE to complement the platforms optimized for 10 and 40 GbE, which have been shipping since late 2014.

Some observers asked us, “Does the market really need 100 GbE yet, or is this going to be a niche product for a while?”

Our answer is clear: The time for 100 GbE is now and we plan to sell a lot of it.

I understand where the question is coming from. Though 100 GbE has been hyped for some time, early implementations were expensive, bulky and power-hungry. But as with every prior transition between Ethernet data rates, 100 GbE has clearly reached the tipping point. 100 GbE ports on datacenter switches are now more cost-effective and provide better density than 10 or 40 GbE for anyone who needs the bandwidth. QSFP28 optical modules support 100 GbE in the same form factor as the popular 40 GbE QSFP+, and at a much higher density than alternatives such as CFP or CFP2 modules.

As a result, 100 GbE ports using QSFP28 are taking off inside the datacenter. Based on various analyst projections, it looks likely that 100G datacenter switch port shipments will surpass 40G within 2 years and comprise over a third of all new ports by 2018. But those aggregate statistics hide the fact that hyper-scale datacenter operators, such as Internet Content Providers (ICPs) and Internet Exchange (IX) providers, are leading the 100G adoption and moving much faster. They are already telling us that they have an urgent need to extend 100 GbE links between their datacenters this year.

That’s why Cloud Xpress with 100 GbE is perfectly timed for the market.

And, as far as we can tell, Cloud Xpress will also be the first optical transport product of its class shipping 100 GbE ports based on QSFP28.

The density of QSFP28 allowed us to include five 100 GbE ports and still have room for sixteen 10 GbE SFP+ ports on the narrow 2 RU faceplate. This allows customers to fill up the 500 Gb/s line capacity with a flexible mix of 10 and 100 GbE links – without any breakout cables — which can be useful in many growth and migration scenarios.

As we look ahead, we can see even greater 100 GbE densities aligning with increasing optical line capacity provided by Infinera’s unique PIC technology, which will allow the Cloud Xpress family to continue to scale along with our customers’ ever-growing bandwidth demands. Come along and ride the 100G wave!

Infinera Named Ne Plus Ultra of the Rapidly Growing ICP and DCI Market by IHS

Mark Showalter, Senior Director, Marketing Communications

Mark Showalter, Senior Director, Marketing Communications

By Mark Showalter

While much of the optical industry is enjoying the 17th Annual Next Generation Optical Networking show in Nice this week, I am basking in the light of the recently published 2015 Optical Network Hardware Vendor Scorecard from Andrew Schmitt, research director, Carrier Transport Networking at IHS (formerly Infonetics Research). In the report IHS names Infinera the ‘ne plus ultra of the rapidly growing Internet content provider and datacenter interconnection market’.

Latin is not my strong suit so I referred to the Cloud to look up what this meant and found the following from Merriam-Webster:

Definition of NE PLUS ULTRA

1 :  the highest point capable of being attained

2 :  the most profound degree of a quality or state

Hard to top that! The report further highlights Infinera as leading with ‘outstanding customer perceptions, large market share gains and tight finances.’

Last year, Infonetics Research ranked Infinera the top optical vendor in the 2014 Optical Network Hardware Vendor Scorecard, reporting “Infinera is #1 this year as a result of very high ratings among customers for technology innovation, reliability, and service and support.”

This year, IHS (formerly Infonetics Research) refined their scoring system and ranked each of the top ten optical hardware vendors into one of three categories: Leader, Established or Challenger, depending on overall score. We are thrilled to see Infinera named as one of three to make up the top category – Leader.

Andrew Schmitt offered further insight into the ranking: “Infinera has excellent scores across the board and as such it is no surprise that Infinera is ranked as a leader. Infinera has market presence with excellent scores from customers for product reliability, service and support. The company also had excellent momentum as a result of big market share gains in 2014 and is the top perceived vendor when it comes to technology innovation.”

While all of us at Infinera are delighted by this award, I think our CEO Tom Fallon says it best:

“The IHS Optical Network Hardware Vendor scorecard shows that Infinera’s focus on customer satisfaction, quality and market leading innovation continues to resonate with global network operators. We are honored to receive the highest recognition from IHS for the second year running based on our success deploying Intelligent Transport Networks around the world.”

Reflecting on Our Image in the Glassdoor – Taking an Honest Look at Our Position in the Employment Market

Jessy Kirkwood, Sr. Manager, Internal Communications & Training

Jessy Kirkwood, Sr. Manager, Internal Communications & Training

By Jessamyn Kirkwood, Senior Manager, Internal Communications and Training

Since 2008, Glassdoor has offered a behind-the-scenes glimpse into what it’s like to work for the top US companies. This information can be extremely valuable to potential employees in determining whether an organization is a good fit for their career objectives. However, the same data can also provide helpful insights for corporations looking to understand themselves and their industry better. At Infinera, we see it not only as an opportunity for others to preview our culture and values, but for us to reflect upon the image looking back at us in the glass.

Unlike engagement surveys or exit interviews, which limit responses to only current or departing employees (and those who take the time to share their feedback), Glassdoor includes former employees, expanding the pool and introducing different perspectives. The most recent summary of Infinera and its competitors offers a fascinating view on where our industry stands in the employment market.


As a whole, the optical networking business appears to raise up strong senior leaders. The CEO approval rating for three out of four of the companies below is well above average for Glassdoor. Organizations, like Infinera that have a larger concentration of engineers, tend to be more objective and analytical about the performance of their executives and less ‘sentimental’. As a result, to see high marks in this category is somewhat surprising and encouraging. Our industry as a whole is doing something right, grooming leaders who are authentic, believable, capable and smart, and who have the support of their employees behind them.




Infinera Review: “Our founders and execs are real leaders who could have retired decades ago but love to compete, win, make more money and provide opportunities for others to do the same.”

Review of Company in same Telecom Space: “The executive team has a good strategy.”

Infinera Review: “Upper management does an outstanding job of communicating the objectives and goals of the company. This is a special place to work. Keep doing what you’re doing!”

However, it wouldn’t be fair to focus only on what we are doing right. One area where the industry seems to be underperforming is career opportunities. While these numbers were notably higher for Infinera, we still see this as a substantial area for growth as a company and as a player in our market. There’s a number of potential factors that we might point to as influencing this reality.




First off, most people who find themselves in the optical space are highly specialized in what they do. So the chance to move into an entirely different department and apply their hard earned skills and education to a less relevant area can seem unproductive. A non-linear career path has proven to open doors, but can sometimes feel like a step back rather than forward for those accustomed to a traditional progression of skills and responsibilities. While we did not see this factor reflected heavily in our Glassdoor reviews, the sentiments about the caliber of our employees and the level of talent could be interpreted as a potential by-product. If everyone assumes that their coworker’s job can only be performed by a seasoned expert, they are less likely to assert themselves if that job were to become available.

Infinera Review: “The biggest challenge at Infinera is that 98% of the employees are highly motivated and super talented, so standing out as a top level employee isn’t easy but I’d rather work with super talented people…”

Infinera Review: “Challenging problems to solve, working with a lot of smart people you can learn from.”

Another factor, particularly in our Silicon Valley headquarters, is the history and legacy of our industry. Optical networking is hardly synonymous with sexy start-ups and limitless breakthroughs. In the past, our customer-base was comprised of heavily regulated companies with deep roots, long-held traditions of doing business a certain way and, in some cases, a resistance to change. Fortunately, that is no longer the landscape and our industry truly has embraced a new approach to telecommunication solutions. Infinera’s technology is broadly recognized as cutting edge and something that the world has never seen before—we are on the precipice of a new networking reality. Now, the onus is on us and our competitors to continue to champion that change; to invite people to view us as leading innovators, not just in optical but overall and to appreciate the transformative influence we exercise over the growth and future of global communications. Our reviews on Glassdoor are affirming in this respect but, again, we don’t see this as a reason to sit back but rather an invitation to challenge ourselves even more.

Infinera Review: “Very committed group of people. A lot of passion on the technology and networking solutions. I love coming to work every day. Reminds you that the start-up vibe persists. Kudos to the senior management team for holding the fort and expanding the technology.”

Infinera Review: “Cool technology. Innovative optical system, original software and architecture excellence.”

Infinera Review: “Strong team, smart people, still has the start-up / can-do mentality.”

Infinera Review: “Very good and open culture, good visibility, opportunity to work with newer technology.”

On a personal note, I have experienced the opportunities for career growth at Infinera, having worked in a number of different areas (Operations, PIC, Office of the CEO and BOD, Internal Communications and Leadership Training) in my 6 plus years with the company. I’ve seen how doors can open when you press on them long enough and are willing to do things that might originally feel like a step backward. But, as any career advisor will confirm, you must be willing to press, go outside your comfort zone and be supported by a culture where you see others doing the same. Not every door is glass: you can’t always see what’s on the other side. Still, it’s important that we as a company and as individuals continue to push on those doors and take those risks to find out what’s possible.

Infinera’s overall standings according to Glassdoor:
