A simple criterion is presented which describes the impact of interchannel nonlinearities in wavelengthdivision multiplexing systems with electronic precompensation of intrachannel nonlinearities. Furthermore, limits of electronic precompensation imposed by multiplexer filter bandwidth are explored.
