Telcordia hosts FSAN's fifth GPON interop
NOVEMBER 8, 2007 -- Telcordia (search for Telcordia) recently hosted the fifth Full Service Access Network (FSAN; search for FSAN) interoperability test event at its U.S. headquarters. The event was organized by Telcordia in cooperation with FSAN (an affiliation of international network operators and telecom vendors), Corning Cable Systems (search for Corning Cable Systems), and Shenick Network Systems (search for Shenick).
The three-day event allowed vendors to verify their understanding of the relevant industry specifications and to validate implementations early in the development process; thereby avoiding costly changes later in a GPON product's commercial life. In all, 15 system and device vendors participated, interconnecting GPON products and reference designs at Telcordia to test interoperability.
"We are very pleased with the success of this test event, which was due in part to the excellent preparation by Telcordia and all the participating GPON system and device vendors, and the maturity of the GPON technology demonstrated at this event," said Regis Coat (France Telecom) and Paolo Solina (Telecom Italia), co-chairs of the FSAN Interoperability Task Group. "FSAN is currently working to identify and mitigate OMCI [ONT Management & Control Interface]-related service provisioning interoperability issues between different manufacturers' GPON implementations. The progress made at the Piscataway test event was an excellent step toward our goal of full OMCI interoperability across a wide range of GPON implementations."
The ITU G.984 GPON standard enables line rates of 2.5 Gbits/sec in the downstream direction (central office to customer) and 1.2 Gbits/sec in the upstream direction (customer to central office).
The event involved 15 GPON equipment and IC vendors including Adtran, Alcatel-Lucent, BroadLight, Cambridge Industries Group, Comtrend, Conexant, Ericsson, Freescale, Huawei, Ikanos Communications, Nokia Siemens Networks, Occam Networks, PMC-Sierra, TXP Corp., and ZTE.
The main goal of this test event was to demonstrate the interoperability of GPON equipment at the service layer in a full OMCI context. Detailed test cases were carried out to verify the provisioning of a number of Ethernet flow handling scenarios in a multi-vendor environment.
The test infrastructure used at this event included the Shenick diversifEye triple-play service test platform and optical distribution network (ODN) fiber and the outside plant distribution elements of Corning Cable Systems' Evolant Solutions for Access Networks. Future GPON test events will expand the number of service models and address quality of service (QoS) performance.
