BANGALORE, INDIA: Broadcom; PMC-Sierra; Opulan and ZTE demonstrated interoperability of symmetric 10G-EPON products, in Shanghai, China recently, during a showcase hosted by ZTE Corporation.

The showcase was open to participants of the IEEE 1904.1 Working Group meeting in Shanghai.

Each vendor supplied an OLT and a variety of ONUs (supporting both 1G-EPON and symmetric 10G-EPON), connected in a multi-vendor configuration to demonstrate complete interoperability.

Co-existence of 1G-EPON and 10G-EPON on the same network also was demonstrated successfully, thus validating a critical feature for operators with large volumes of 1G-EPON deployed in their networks.

10G-EPON’s robust and cost-effective coexistence solution protects network operators’ existing 1G-EPON deployments and allows a graceful, gradual migration to higher data rates on an as-needed basis.

Rapid development of 10G-EPON products was possible primarily because of the incremental development strategy adopted during the work of IEEE 802.3av Task Force, where existing specifications of 1G-EPON were leveraged to the greatest extent possible.

This is especially critical in terms of the EPON management, based on extensions to IEEE Std 802.3 Clause 57 OAM, used in mass deployment 1G-EPON systems and now only updated to provide support for 10G-EPON.
