Full Service Access Network Organization Recommends Path for Next-Generation PON Technology

Industry Experts in FSAN Agree on Technology for NG-PON2 for Greater System Capability and Enhanced Services

Santa Clara, Calif. — July 16, 2012 — In an effort to drive toward a common goal of true broadband fiber access networks, operator members of the Full Service Access Network (FSAN) organization unanimously agreed on an approach regarding next-generation passive optical network (PON) technology.

The agreed upon approach is a time and wavelength division multiplexed (TWDM) solution with optional wavelength division multiplexed (WDM) overlay extensions designed for the next generation passive optical network. NG-PON2 is the next iteration of PON technology, designed to meet a broad range of projected communication needs such as business and mobile backhaul applications as well as residential access. This approach means NG-PON2 can support increased capacity, higher light-to-port ratios, improved interoperability, and enhanced services.

The FSAN decision was based on operator network requirements, desired availability timeframe, and technology risk. By agreeing to this focused direction, industry efforts and NG-PON2 standardization work can progress through contributions to ITU-T Study Group 15 – Question 2 Access Working Group (Q2/SG15). The resultant ITU-T Recommendations will define standards for the NG-PON2 architecture and technology.

“FSAN made significant progress during its late June meeting in Santa Clara, Calif., when the group focused on developing draft text for the NG-PON2 Requirements and Physical Media Dependent Layer specifications,” said FSAN Chair Martin Carroll of Verizon. “If rapid progress can continue to be made, standards could be ratified as early as 2013, which will give the industry a clear path to more advanced, highly capable broadband access networks.”

While still developing enhancements to GPON and XGPON, FSAN also is focused on defining the NG-PON2 system. This new system will increase PON capacity to at least 40Gb/s and deliver services of 1Gb/s or more with platforms that could be deployable in 2015. Since it began working on NG-PON2 in 2010, FSAN has progressed from operator agreement on requirements to the analysis of candidate technologies and solutions that are supported by in-depth technical contributions from highly experienced industry leaders around the world.
