Calix Innovation and Expertise Paves Way for NG-PON2 to Reach Mass Market

LOS ANGELES, CA – March 21, 2017 – Calix, Inc. (NYSE:CALX, news, filings), the world leader in Subscriber Driven Intelligent Access, is pioneering the rapid deployment of advanced passive optical network (PON) technologies among service providers globally, including NG-PON2technology – a major leap forward in fiber access services that lays the foundation for dramatic operational and capital cost reductions while greatly improving the subscriber experience. Capable of increasing symmetrical broadband speeds by ten-fold over existing widely deployed GPON networks while coexisting with GPON over the same fiber infrastructure, NG-PON2 takes the possibilities of a single unified access network for residential, business, and mobile backhaul to an entirely new level. By converging services network onto a common optical distribution network (ODN), remotely managing subscriber split ratios, and providing services separation using wavelength mobility, NG-PON2 fundamentally changes how service providers think about total cost of ownership (TCO) in their networks. Calix recognized the potential of next generation PON technologies early-on, and has invested its resources heavily in anyPON technologies – XGS-PON, NG-PON2, and 10G-EPON – both through its own product innovation as well as fostering the ecosystems necessary to catalyze mass market commercialization of each technology. This commitment to the full array of PON technologies, coupled with the power of the Calix AXOS platform that enables unrivalled speed of implementation and deployment of the latest innovations on Calix E-Series systems, has uniquely positioned the company’s AXOS systems portfolio to become an anyPON portfolio – capable of delivering cutting edge fiber access solutions across all PON technologies.

NG-PON2 represents the latest frontier of PON innovation. Calix’s deep PON expertise and the clear advantage of its AXOS platform, the only true SDA, and anyPON technologies has played a leading role in defining the standards, ecosystem, and milestones that demonstrate the promise of NG-PON2 including:

• NG-PON2 Council Leadership – Calix resources founded the NG-PON2 Forum in 2016, which has since been integrated into the newly formed Broadband Forum NG-PON2 Council. Bernd Hesse, Senior Director of Technology Development at Calix, is the newly appointed Chair of the NG-PON2 Council.
• FSAN Leadership – Calix has held leadership roles in Full Service Access Network (FSAN) since its infancy, driving the standardization of BPON, GPON, XGS-PON, and now NG-PON2 technology and their advancements toward commercialization.
• First Demonstrations of NG-PON2 Channel Bonding – Leveraging its AXOS E7-2 Intelligent Modular Access System, Calix demonstrated the world’s first channel bonding demo of NG-PON2 technology to over 1700 attendees at its 2016 Calix User Group in October.
• First NG-PON2 Interoperability Testing – PON Pioneer Verizon announced in January Calix and partner Ericsson to be one of two NG-PON2 vendor solutions to tested in its labs, as well as among the first to pass Verizon interoperability testing.
• First NG-PON2 Deployment in a Live Network – Calix customer Northpower Fibre announced in February that it was the first company in the world to deploy NG-PON2 technology in a live network.

“Since the birth of PON, Calix saw the potential of this fiber access technology and has been the leader in bringing its promise to reality,” said Shane Eleniak, vice president product line leadership at Calix. “Now as NG-PON2 hits its stride, we are seeing the emergence of a technology that can be truly transformational to services provider – redefining not only their services possibilities, but also their ability to consolidate multiple networks into one. Calix is proud of its leading role in leveraging AXOS, with its containerized individual software components and fully abstracted software and hardware architecture, across its E-Series portfolio to bring the most recent PON technology innovations to the mass market first. We look forward to seeing how service providers and their subscribers will leverage the best Calix anyPON technologies and Calix Cloud to deliver an unmatched subscriber experience to the home, to the business, and as backhaul.”
