MB87Q2020 : 43G Ultra-FEC Chip
PDF MB87Q2020 Fact Sheet [68.0 KB]
The MB87Q2020 is a multi-rate multiple forward error correction code device supporting Sonet/SDH, OTN and ClearChannel signals. The device can be configured in transceiver and regenerator modes at 40/43 Gbit/s data rates.
In transceiver mode either a constant bit rate 40Gbit/s signal (CBR-40G) (Sonet/SDH or clear channel) or an OTU-3 signal can be mapped into and extracted from a line side G.709/798 compliant transmission format. For Sonet/SDH client signals reduced receive and transmit byte processing according to ITU-T G.707/ANSI T1.105 is supported.
In regenerator mode the MB87Q2020 provides full G.709/798 compliant byte processing with several FEC converter options.
