PQ40T: 4x10G/40G OTN Framer/Mapper/FEC

PQ40E is a highly-integrated VLSI device designed for carrying 4x 10G or 1x 40G Ethernet services by using IEEE802.3 in LAN/WAN environment or by using OTN standard in Metro and Long Haul networks. It is ideal for Carrier-Ethernet Switch/ Router and DWDM systems as this device can be a simple multi-channel PHY layer device, supporting pure 10GbE or 40GbE Carrier-Ethernet networks, as well as a highly integrated Framer/FEC device, supporting WAN/OTN network via its rich suite of 10GbE/40GbE over OTN mapping modes. The device has integrated multi-purpose IOs to support seamless interface to various 10G/40G optical modules (XFP/SFP+/CFP/Serial CFP/SFI5.1) and also to NPU/Switch device (XAUI/ RXAUI/XLAUI/Interlaken).
