Abstract
A method for improving the resilience of a communication channel (such as an optical communication channel) to correlated errors (e.g., burst errors), the channel is being formed by a time-multiplexed aggregation of a plurality of lower rate constituent lanes and employs a Forward Error-Correction (FEC) mechanism for forming codewords from data carried by the constituent lanes. Accordingly, the distribution of errors among the codewords is modified by introducing, at the transmitter side, specific delays to the transmission times via the constituent lanes, relative to each other.
