MAY 5, 2010 -- ZTE Corporation demonstrated the interoperability of symmetric 10G-EPON products to participants of the IEEE 1904.1 Working Group meeting in Shanghai, China.
Interoperability among products was demonstrated by four vendors: Broadcom PMC-Sierra, Opulan, and ZTE. 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.
System performance was examined for a number of realistic and challenging test configurations that reflected the specific requirements of major service providers, describes a representative. These tests included physical-layer connectivity, MAC-layer connectivity, MPCP discovery, dynamic bandwidth allocation, service setup, security and authentication, and connection management.
Coexistence of 1G-EPON and 10G-EPON on the same network also was demonstrated, validating a critical feature for operators with large volumes of 1G-EPON deployed in their networks. 10G-EPON’s coexistence solution protects network operators’ existing 1G-EPON deployments and allows a gradual migration to higher data rates on an as-needed basis, says a representative.
Rapid development of 10G-EPON products was possible primarily because of the incremental development strategy adopted during the work of IEEE P802.3av Task Force, where existing specifications of 1G-EPON were leveraged to the greatest extent possible.
This 10G-EPON interoperability event marked the world’s first interoperability showcase of a next-generation, symmetric, 10 Gb/s PON, and represents a milestone in the introduction of symmetric technology in the access network, says a company representative.
Participants of the IEEE 1904.1 Working Group (SIEPON, www.siepon.org) meeting were able to attend this event. The IEEE P1904.1 standards project, sponsored by the IEEE Communications Society is focused on developing service-layer interoperability specifications, which incorporate requirements from operators around the world.
