A Product-Coded WDM Coding System - Communications, IEEE Transactions on

Forward error correction is a feasible approach to decline the bit error floor of lightwave systems, arising from the fact that a simple single-error-correcting code can reduce the error floor from O(P,) to O(P'). Here we propose a novel wavelength demultiplexer (WDM) coding system using product code to improve performances of WDM systems with an error floor caused by fiber dispersion or system noises.
