LuminentOIC Announces Industry's First End-to-End G-PON Solution



HSIN-CHU, Taiwan and CHATSWORTH, Calif., March 2 / -- LuminentOIC, a leading supplier of metro & access transceivers and Fiber-to-the-Premise solutions, today announced the availability of the industry's first ITU-T G.984 G-PON compliant end-to-end transceiver solution.

LuminentOIC's G-PON OLT transceiver is the industry's first and only module that is fully compliant to the ITU-T G.984 G-PON timing parameters requiring only 6 bytes of preamble between bursts of data. Unlike GE-PON systems that have a relaxed requirement of 128 bytes of preamble between bursts of data, LuminentOIC developed in-house technology to meet the stringent timing requirements of G-PON systems. The tighter timing requirement of G-PON systems versus GE-PON systems enables higher throughput efficiency. LuminentOIC's OLT transceiver is available in both a pigtailed SFF and receptacle pluggable SFP form factor. The first product release is for 2.5 Gb/s downstream, 1.25Gb/s upstream data transmission.

LuminentOIC also announced the immediate availability of G-PON ONT triplexer transceiver, offering voice, video, and data. The triplexer transceiver operates at 1.25Gb/s upstream, 2.5 Gb/s downstream, and employs a temperature hardened DFB transmitter, an APD receiver and a CATV video receiver. A digital-only version is also available in the both same form factor or in a pigtailed SFF.

"LuminentOIC's technical leadership in G-PON burst receiver technology has enabled us to release the industry's first-end-to end G-PON solution, and the only fully complaint G-PON OLT transceiver," said Ley Mee Hii, Director of PLM, FTTP. "We intend to build upon our market dominance in the North American B-PON market and leverage our high volume B-PON manufacturing infrastructure to seamlessly transfer our G-PON product line into volume."

LuminentOIC's G-PON product family has been sampling since Q3 2005 and is currently in pilot line production.
