Methods, systems, and computer readable media for testing of hardened forward error correction (FEC) implementations

Abstract:

According to one method for obtaining information from a hardened forward error correction (FEC) implementation, the method occurs at a test device implemented using at least one processor and at least one memory. The method includes copying data from a data stream that is to be processed by a hardened FEC engine; delaying the copied data while the hardened FEC engine generates corresponding error corrected output using the data; comparing the copied data and the corresponding error corrected output for differences; and generating FEC related metrics based on the comparison.
