Chorus of New Zealand, Chunghwa Telecom, and Australian National Broadband Network overseer NBN Co. have joined with seven technology suppliers to create the 25G Symmetric PON Multi-Source Agreement (25GS-PON MSA). The group hopes to step in where the ITU-T SG15/Q2 could not – creating consensus on a standardized approach to symmetrical 25G-PON operation within the GPON domain.
The IEEE recently ratified specifications for both 25G and 50G PON under IEEE 802.3ca. The 25GS-PON MSA members say they have leveraged the IEEE’s work to create their own specification, which marries the IEEE specs with a Transmission Convergence (TC) layer that is an extension of XGS-PON.
Joining Chorus, Chunghwa Telecom, and NBN Co. in the effort are AOI, Ciena, MACOM, MaxLinear, Nokia, Sumitomo Electric Industries, and Tibit Communications.
“25-gigabit symmetric PON is an important next-step and a natural evolution for fiber networks, especially since it leverages existing technologies,” commented Julie Kunstler, principal analyst at Omdia, via an MSA press release. “Numerous operators are interested in 25GS-PON, for use in 5G transport as well as enterprise and business services. Establishing an MSA to bring this technology to market demonstrates innovation, leadership, and customer-centric market awareness on the part of its members.”
More information, including the initial specification set, are available from the MSA’s website.
