Ten major communication industry operators and vendors today announced the signing of a 25G symmetric PON multi-source agreement (25GS-PON MSA) with the goal of promoting and accelerating the development of 25GS-PON. The MSA Group has defined the 25GS-PON specification needed to address the gap between 10G XGS-PON and 50G PON in the ITU-T. The MSA was created after the ITU-T SG15/Q2 group did not reach consensus to standardize 25GSPON, which is seen as a crucial technology by many of the world’s top operators and vendors.

The formation of the 25GS-PON MSA Group underscores how important 25GS-PON is to the industry as it seeks a cost-effective and timely network upgrade path that can meet the needs of the mobile 5G era and large-scale enterprises where symmetrical connections become increasingly important. As a first step, the 25GS-PON MSA Group created a specification for 25GS-PON which includes optical specifications based on the IEEE 802.3ca 25G EPON standard, along with a Transmission Convergence (TC) layer that is an extension of XGS-PON. The MSA Group will also promote and catalyze the market development for 25GS-PON.

Julie Kunstler, Principal Analyst at Omdia, said: “25 gigabit symmetric PON is an important next-step and a natural evolution for fiber networks, especially since it leverages existing technologies. 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.”

The founding members of the 25GS-PON MSA Group include: AOI, Chorus, Chunghwa Telecom, Ciena, MACOM, MaxLinear, NBN Co., Nokia, Sumitomo Electric Industries, Ltd, and Tibit Communications.

The 25GS-PON Group has published a website with a copy of the 25GS-PON specification and additional information at www.25gspon-msa.org. The 25GS-PON MSA Group invites other industry leaders to join the group to advance the technology and market.
