EPON chips roll for China telecom market

PMC-Sierra Inc. has announced the availability of EPON optical network unit (ONU) and optical line terminal (OLT) silicon devices that are said to be the first to support China Telecom-defined algorithms and features for the China telecom market.

The PAS6301 ONU for customer premises equipment and the PAS5201 OLT for central office equipment together provide an end-to-end EPON solution. The two SoC devices are the first to be designed to meet China Telecom standards that define data encryption and decryption algorithms, QoS procedures and classification protocols, making them suitable for emerging high-volume deployments in China.

These devices extend PMC-Sierra's product leadership in high-volume EPON devices by providing the first enhanced FEC in both ONU and OLT devices, enabling higher split ratio and longer physical links in the access network. In addition, the PAS6301 includes VoIP service support to lower the cost of providing voice over fiber. Both devices support large packet buffers for higher quality IPTV broadcast capabilities, which is a significant improvement over previously available devices.

Samples of the EPON PAS6301 ONU and PAS5201 OLT devices are available today. The PAS6301 ONU is available in a PGBA 456 package and the PAS5201 is available in a BGA 376 package.
