Fec coding rate
WebFeb 13, 2024 · FEC Block 1 is coded with S=8 for maximum redundancy and includes the coding indicator (CI) which was used to code FEC Block 2 (i.e. S=2 or S=8). Each block ends with a TERM value which is a bit pattern of 000. During bit stream processing, the TERM value has the effect of resetting the FEC encoder. WebMar 15, 2024 · FEC that results in a 1 to 2 dB gain on a 100G network, for instance, translates to a 20% to 40% greater reach.

WebConvolutional code with any code rate can be designed based on polynomial selection; however, in practice, a puncturing procedure is often used to achieve the required code rate. Puncturing is a technique used to make a m/n rate code from a "basic" low-rate (e.g., 1/n) code. It is achieved by deleting of some bits in the encoder output.
