2016 is looking like the year metro networks start transitioning to 100G. So, what better way to start the year than talking 100G at NANOG, where leaders in networking converge?
When the NANOG 66 conference kicks off next week in San Diego, LightRiver and Infinera will be right in the middle of the action, showing leadership in 100G wavelength division multiplexing (WDM). Infinera, of course, brings its low power and small form factor technology, including the Cloud Xpress with 100 GbE interfaces. LightRiver will showcase our 100G expertise and promote our unique Factory Built Network™ practice at the 4:00 p.m. conference break on Tuesday, February 9th. We’ll also be at the Infinera table during the Infinera sponsored Beer & Gear event, Tuesday night February 9th, 6:00 p.m. to 8:00 p.m.
It’s no accident that both of our companies are in sync about the future of 100G in the metro. LightRiver and Infinera have a long-standing partnership, with complementary strengths and aligned vision of the future of optical transport networks. In fact, just last fall we celebrated over 10 years of a strong working relationship, with Infinera bestowing its “Gold Level Partner” certification on LightRiver.
Looking ahead, we see a huge opportunity for our companies working together to address the ever-growing demand for scalable optical networks generally, and in particular, the demand for 100G in metro networks.
Contact us to set up a meeting with LightRiver and Infinera to discuss your metro 100G applications. See you in San Diego!

Infinera’s Advanced Coherent Toolkit (ACT) Delivers up to 60% More Performance for Submarine and Terrestrial Optical Cables
VP, Optical System Architecture
Infinera recently validated our new Advanced Coherent Toolkit (ACT) over one of the world’s longest submarine cables – Telstra’s Endeavour cable, which connects Sydney to Hawaii. The Infinera ACT consists of new techniques that enable increased capacity and reach on subsea and terrestrial cables – up to 60% depending on the particular cable. By combining our advanced FlexCoherent™ digital signal processor (DSP) electronics and large scale photonic integrated circuit (PIC) optics, Infinera has built a strong engineering capability around novel coherent approaches.
There was a time when particularly long or challenging subsea routes just couldn’t be closed using the highest data rates available. Network operators were faced with the prospect of using hop-by-hop regeneration (regen) through intermediate points where they could bring the cables up to remote islands in the middle of the ocean. In these scenarios, the network operators took a hit on the operational cost of running an active regen sites.
As coherent technology has evolved, the question is no longer whether a particular cable span can be closed – it’s now a concern of how much capacity can be extracted from the route. Those costly regen sites in existing cable systems are now being “glassed through,” and new cable systems are being laid over longer direct spans that would have been impossible to close in the pre-coherent days.
The move to coherent detection means that network operators can unlock the incredible power of modern signal processing to increase capacity on very valuable assets – undersea and terrestrial optical cables. When assessing the significant expense of deploying a submarine cable, which can run into several hundred million dollars, the value of increasing fiber with no replacement of undersea elements (wet plant) is clear.
In the first coherent super-channel era, the DSP in the receiver allowed Infinera and our customers to conquer channel impairments such as chromatic dispersion and polarization mode dispersion. As we move toward the second coherent super-channel era, digital processing and signal manipulation techniques are added to the transmitter (TX-DAC), in addition to introducing enhanced receiver-based technologies.
A TX-DAC is just one of the innovations in the new Infinera Advanced Coherent Toolkit. There are multiple advanced and unique algorithms in the ACT that allow operators to tune a particular set of waves in order to maximize the capacity they extract from the fiber across both subsea and terrestrial networks: (more…)
Quality At Our Core: Infinera’s Commitment to Quality and Continuous Improvement in Optical Network Transport Technologies
Director of Quality
At Infinera, we take quality seriously. We’ve maintained that focus from our founding in 2000, when we introduced photonic integrated circuits (PICs) that integrate hundreds of optical functions and leverage modern chip fabrication techniques to bring new levels of reliability to optical components. We combine this unique technology into wavelength-division multiplexing (WDM) systems, such as the DTN-X built with software and hardware that are wrapped in robust unit and system test processes.
In fact, ultra-reliability is one of the four key attributes of what we call the Infinera Experience and a principle of Infinera product designs from the ground up. Today, our Intelligent Transport Networks enable network operators to efficiently deploy scalable WDM systems that carry information in long-haul, subsea, data center interconnect/cloud and now metro networks.
Infinera is part of QuEST Forum’s initiatives, playing an active role in defining best practices, quality measurement and management approaches and quality benchmarking, all of which ultimately are influencing if not evolving into industry measurement standards.
QuEST Forum, a global association of companies including service providers, suppliers and liaisons, is dedicated to impacting the quality and sustainability of products and services in the information and communications technology (ICT) industry. QuEST Forum was formed in 1998 to pursue and achieve a goal of global ICT quality and industry-wide performance excellence.

Co-founder and President, Infinera
As we ring in a new year, I find it inspiring to consider how different Infinera is today than it was a year ago. Even more interesting is to think back to 2004, when our first platform shipped, and consider how much has changed in the optical market over those 10-plus years.
Over the last decade, the optical industry has gone through dramatic changes. There has been widespread consolidation while online video and the explosion of business and consumer applications in the cloud have simultaneously driven significant increases in bandwidth requirements.
In 2000, Infinera founders had the foresight that photonic integrated circuits (PICs) would bring Moore’s Law-like performance to optical transport and revolutionize the optical transport industry. Infinera delivered on this insight, developing unique large-scale PICs enabling innovative optical networking solutions for the most demanding networks.
Infinera’s earliest PIC-based Intelligent Transport Networks enabled network operators to efficiently deploy scalable WDM systems to carry information primarily in long-haul and subsea networks. Fast forward just over ten years and Intelligent Transport Networks support the growing demand for high bandwidth across various network locations from the core all the way to the access.
In 2012 Infinera entered the 100G long-haul market with a PIC-based platform, skipping over 40G. It was a big bet and one that paid off. We believe our DTN-X Family played a significant role in influencing the acceleration of the 100G long-haul market. Today, Infinera is an industry leader, having shipped over 24 percent of all 100G long-haul ports ever sold since 1Q-10, according to Dell’Oro*.
In 2014, Infinera introduced the industry’s first metro Datacenter Interconnect (DCI) platform to help service providers with burgeoning datacenter-to-datacenter traffic. The Cloud Xpress, a PIC-based platform purpose-built for the metro DCI application, intersected the inflection point of this rapidly growing 100G market. Today we are shipping Cloud Xpress with 10 gigabit Ethernet (GbE), 40 GbE and 100 GbE interfaces, offering truly optimized rack-and-stack-style DCI platforms.
2015 has been a momentous year for Infinera building out an end-to-end packet optical offering, which addresses the entire metro and long-haul transport market.
A few of the most significant accomplishments include:
- Introducing our Open Transport Switch (OTS), an SDN abstraction software module and announcing a live NaaS deployment on the Pacnet Enabled Network (PEN), now part of Telstra
- Expanding the Cloud Xpress platform with 100 GbE client to match customer specific requirements
- Completing the acquisition of Transmode, a leader in metro packet-optical networks
- Extending the DTN-X Family to metro core and regional network applications with XTC-2
- Introducing new hardware and software capabilities that unify Infinera’s award winning long-haul DTN-X Family with the Infinera TM-Series metro packet-optical solution
- Introducing the XT-500 platform, a new member of the DTN-X Family for long-haul interconnect applications, highlighting Infinera’s continued investment in long-haul solutions
- Receiving 100 GbE MEF CE 2.0 certification on Infinera’s Packet Switching Module (PXM) for the DTN-X Family
Out of these milestones, one of the most significant was Infinera’s acquisition of Transmode, bringing together two industry innovators. This acquisition, in conjunction with the introduction of our XTC-2/2E platform, enables Infinera to address the metro market as it moves to 100G and to offer an end-to-end product portfolio to address the $15.3 billion global optical networking market**. Founded in 2000, Transmode delivered some of the world’s first metro-optimized WDM products. Over the years Transmode shipped over 50,000 chassis into networks across the globe. In 2015, just prior to the acquisition by Infinera, the company introduced the PT-Fabric, a terabit-level packet transport switch for the TM-Series. This device enables real 100G packet-optical networking in metro networks and can be installed in any of the 20,000+ TM-3000 or TM-301 chassis that the company has shipped since 2001.
As I look ahead to 2016 I expect network operators will continue to transform their networks to 100G and move to cloud-based architectures. I look forward to helping our customers succeed in their markets with a best-in-class end-to-end optical portfolio, systems that allow rapid bandwidth and service activation to use time as a weapon all with an underpinning of world class customer service.

VP Product Management and Strategy
At this year’s ECOC Market Focus, I had the pleasure of sharing some insights into how network operators are leveraging new converged packet-aware optical transport solutions to streamline their core IP/optical networks. We are already witnessing broad industry adoption of converged OTN/WDM platforms in the core of the network as service providers are realizing that integrated OTN switching facilitates faster service delivery, simpler bandwidth management and more efficient wavelength fill. With the emergence of high-speed, sophisticated packet-processing cards coming onto the market, an added level of high-speed packet intelligence and capability is now enabled within the OTN/WDM core.
Newsworthy? We think so.
In today’s environment, converged OTN/WDM is widely deployed and operators are pressured to drive further optimization across their multi-layer networks. This concept (and its realization) has gotten the attention of progressive network operators, due to its ability to further reduce total networking costs by offloading core routers of basic packet transport and aggregation functions and enabling high-speed Ethernet services directly within the transport layer. This results in a reduction in the number of router ports required in networks. By enabling L2 packet transport, aggregation and services functions within the optical/OTN backbone, operators now have access to new tools to enable more efficient router interconnect and bandwidth engineering capabilities directly within the transport layer, without having to send traffic up to the router layer. This allows the service provider to more flexibly switch packet traffic at the most appropriate transport layer, and route packets only when needed. The net effect is not only cost savings and enhanced network efficiency, but also guaranteed bandwidth and performance for high speed packet services.
Even in light of the expanded fiber capacity enabled by the 100 Gb/s upgrade occurring on many service providers’ optical backbones, it remains critical to efficiently utilize the bandwidth and minimize the cost of transporting traffic across the IP/optical backbone. The industry is already witnessing the broad deployment of OTN as a means to efficiently multiplex multiple services at different rates into wavelengths, and switch services between wavelengths as needed.
Similarly, the core IP layer is experiencing a technology upgrade cycle in order to accommodate increased IP demands. As in the transport layer, however, it behooves service providers to maximize the utilization of these resources, rather than to just continue the same present mode of operation of the last few decades for scaling IP networks. Rather than throwing more wavelengths and bandwidth at the problem, leading to under-optimized link utilization, and counting on market price erosion at each network layer to lower the cost of the network, many service providers are exploring how to more efficiently utilize their deployed capital, and leverage the underlying optical transport layer where they can. The addition of packet-aware transport gives operators a new way to more efficiently utilize their 100 Gb/s router interfaces, making it easier to push fundamental packet processing and transport functions down into this more cost-effective underlay network. The packet-aware optical underlay is somewhat like an express subway system – instead of relying on a taxi or Uber service to route you through congested city streets, the subway can provide individual choices for getting across town predictably and quickly, bypassing all the traffic intersections.
By providing packet and traffic management functions directly on OTN/WDM systems, operators can immediately benefit from the ability to map packet flows directly from the router into flexibly sized circuits. Each of these circuits acts as a “virtual” wavelength, and can be switched within the transport network to any other router interface. Packet aggregation from multiple virtual wavelengths converging at a common site can now be done within the optical transport layer instead of within the router layer. In many applications, this natively supported aggregation can reduce the number of router ports required, thereby increasing the efficiency of the entire network.
Additionally, with OTN’s ODUflex capability, virtual wavelengths can be flexibly sized. (more…)

Director of MSO Market Segment
Last week, I attended and spoke at the Light Reading Future of Cable Business Services conference in New York. This was the conference’s ninth straight year, once again hosted by Alan Breznick, Light Reading’s Cable/Video Practice Leader. Key discussion areas included cable’s increased efforts to expand beyond small-business market to midsized and large enterprises as well as various delivery technologies that MSOs are deploying or considering to serve the commercial services market.
My panel discussed a hot topic for many cable operators, “Virtualizing Commercial Services,” and primarily explored perspectives on network function virtualization (NFV), and how it could impact cable commercial services. Both software-defined networking (SDN) and NFV are quickly gaining traction in the cable industry as emerging means to improve service delivery, reduce operational costs and cut time to market for new services. Some examples of Infinera’s role in SDN include the first network virtualization of the optical layer, deployed in the Telstra International network, and the unique value of an Open Transport Switch (OTS) which enables programmability in the optical layer, creating unprecedented flexibility to deliver services on-demand with room for growth. NFV is expected to play an even more important role as services and applications migrate into the Cloud.
As with the Telstra International example above, SDN and NFV both offer the promise to transform service provider networks, fundamentally changing the ways networks are built, monitored and managed. The same is true for the services delivered over the network. NFV will allow migration of services and applications into an intelligent Cloud, where software and servers will replace application specific hardware. SDN, with a global network view, will allow enhanced network automation and global optimization, complementing NFV and extending its capabilities throughout the network.
One of the applications I discussed on my panel is Network as a Service (NaaS), where SDN enables virtualization of multiple independent Virtual Private Optical Networks (VPONs) on a common underlying optical transport infrastructure owned by the cable operator. (more…)
