Optical transmitter with encoder encoding processed data including concatenating parity bits to generate fec data blocks

Abstract

A transmitter includes: an input configured to receive, via an electrical interface, encoded data from a host device, the encoded data being encoded at the host device according to a first code; processing circuitry configured to process the encoded data to provide processed data; an encoder configured to encode the processed data according to a second code that is different than the first code, where encoding the processed data includes concatenating one or more parity bits to the processed data to provide forward error correction (FEC) blocks of data; and transmit circuitry to transmit the FEC data over an optical medium.

Dependencies are inferred from the claim text.
