10GBASE-LRM
December 11, 201010GBASE-LRM, (Long Reach Multimode), also known as 802.3aq, uses the IEEE 802.3 Clause 49 64B/66B Physical Coding Sublayer (PCS) and 1310 nm lasers. It delivers serialized data over multi-mode fiber at a line rate of 10.3125 Gbit/s.
Tests for High-speed Transmission Technology
December 11, 2010Only a few carriers have deployed 40-Gbps links in their networks; less than a handful have deployed 100-Gbps technology. But that doesn’t mean there isn’t interest in data rates above 10 Gbps. In a recent interview with Lightwave, Paul Brooks, a product manager in JDSU’s Communications Test and Measurement business segment, described how the increasing attractiveness of high-speed transmission technology has driven new developments in test equipment.

Google joins tech vendors in 100Gbps optical transceiver MSA
December 8, 2010DECEMBER 7, 2010 By Stephen Hardy -- Having stated its need for such a device at several technical conferences this year (including ECOC), Google has joined with Brocade (NASDAQ: BRCD), JDSU (NASDAQ: JDSU), and Santur Corp. to found a 10x10G optical transceiver multi-source agreement (MSA). The MSA seeks to establish compatible sources for low-cost, low-power, pluggable 100-Gbps optical transceivers based on 10 optical lanes at 10Gbps.
