Calix Leverages AXOS to Demonstrate World’s First Multi-10 Gbps Channel Bonded NG-PON2

Channel bonding technology gives service providers deploying NG-PON2 extreme flexibility and scalability when offering next generation services over existing fiber infrastructure

PETALUMA, CAMay 23, 2017 Calix, Inc. (NYSE: CALX), the world leader in Subscriber Driven Intelligent Access, today announced another fiber access technology “first” built on AXOS, the world’s only SDA - the ability to bond multiple channels or wavelengths of NG-PON2 technology over fiber. Working within ITU standards, Calix successfully demonstrated the ability of the AXOS E9-2 Intelligent Edge System to leverage NG-PON2 channel bonding to deliver up to 40 Gbps (gigabits per second) downstream, or 80 Gbps of aggregate bandwidth over a single strand of fiber. This breakthrough allows service providers who are deploying channel bonded Calix AXOS NG-PON2 solutions the ultimate flexibility in addressing, on a single fiber with adjustable capacity, the emerging bandwidth requirements of a variety of demanding service types, including:

  • 5G mobile backhaul
  • High-end business services
  • High-density residential services, including in MDU environments
  • Transport and middle mile

“One of the key attributes of NG-PON2 for carriers is the ability to consolidate business and residential services onto one NG-PON2 network, and we expect NG-PON2 channel bonding technology could help with this convergence, especially as bandwidth needs increase,” said Vincent O’Byrne, director of access technology at Verizon. “This is the reason Verizon has championed channel bonding within the standards as an option to support higher capacities as well as challenged the industry for its standardization and implementation. We believe channel bonding holds the potential to more than double the bandwidth to individual subscribers or network locations and anticipate it could be a means of moving from 10 Gbps to 20 Gbps and beyond without deploying new technologies.” 


The multi-wavelength capability of NG-PON2 technology is already a game changer for service providers in its promise to accelerate network convergence and massively increase available bandwidth capacity. However, the ability to bond NG-PON2 wavelengths takes this opportunity to a whole new level, rewriting the rules that historically governed how quickly and efficiently service enhancements could be deployed in service provider networks. Developed at an unprecedented pace by leveraging the Calix AXOS platform, the NG-PON2 channel bonding breakthrough progressed from a Verizon request to Calix to a live demonstration and was completed in only 12 days. This feat was made possible by the hardware abstracted Calix AXOS platform that can rapidly develop new capabilities, such as channel bonding, while also supporting anyPHY™ and anyPON™ technologies, like NG-PON2, as they emerge. 


“NG-PON2 channel bonding, much like the unique Calix ability to provide gigabit services on via bonding, is another example of the transformative power of AXOS, accelerating the delivery of new technologies, features, and services for all Calix customers,” said Shane Eleniak, Calix vice president of systems products. “Over the past several months, we have introduced several AXOS innovations from connectors like OFx and DPx, which enable seamless migrations to next-generation architectures, to new modules like AXOS RPm, which enable Layer 3 intelligence and routing capabilities in the access network, to AXOS Sandbox, which speeds up and simplifies OSS integration. Today’s NG-PON2 channel bonding demonstration announcement was the next milestone on a fast-growing path filled with cutting-edge Calix AXOS innovations, and we expect this rate of innovation to continue as a hallmark of our AXOS platform well into the future.”
