Gustlin at Cisco) was approved by the 802.3ba Task Force as the baseline PCS proposal on May 16, 2008.

Optical fiber module (PHY) vendors now have the standard of 20 PCS lanes for 100 Gbps and 4 PCS lanes for 40 Gbps. With this standard, development on 40 and 100 Gbps networking sys-tems can begin in earnest. Such development will require intense and accurate testing solutions. In the market’s first public demonstration, Ixia tested a 100 Gbps link using PCS lanes and full line-rate traffic. Ixia, in conjunction with Hitachi, also demonstrated a real-world testing scenario in August of 2009 based on Hitachi’s 100 Gbps frame transmission system. This system was par-tially supported by the Lambda Access Project at the National Institute of Information and Commu-nications Technology (NICT) in Japan.

PCS lanes are a complicated and interesting subject, and are the subject of another Ixia-spon-sored white paper, which can be found at http://www.77cn.com.cn/ixialabs. Pluggable transceiver modules compliant to the CFP MSA are an option for 40 and 100G Gbps interfaces.
