PQ50: 5x10G/40G OTN Framer/Mapper/FEC

PQ60T is a highly-integrated VLSI device designed to carry 6x 10G or 1x 40G multi-service signals by using OTN standard in Metro and Long Haul networks. It is ideal for both Carrier-Ethernet Router and DWDM Transport systems as this device can be used either as a simple multi-channel PHY device with FEC capability, supporting pure 10GbE LAN/IPoDWDM, or as a highly integrated Framer/FEC device, supporting SONET/SDH/WAN/OTN via its rich suite of OTN mapping modes. With its integrated 10G Physical interface and provisional Tri-FEC feature, it provides a seamless interface to XFP/SFP+ optical modules and ensures interoperability among multiple system OEMs.
