FC-1 defines how data is encoded before it is transmitted via a Fibre Channel cable (8b/10b data transmission code scheme patented by IBM). FC-1 also describes certain transmission words (ordered sets) that are required for the administration of a Fibre Channel connection (link control protocol).
Encoding and Decoding
To transfer data over a high-speed serial interface, the data is encoded before transmission and decoded upon reception. The encoding process ensures that sufficient clock information is present in the serial data stream. This information allows the receiver to synchronize to the embedded clock information and successfully recover the data at the required error rate. This 8b/10b encoding finds errors that a ...
