Abstract :
In this paper we evaluate the channel capacity of single-mode fiber systems considering two polarizations. We assume systems perturbed by linear amplified spontaneous emission noise (ASEN), namely, ASEN channels. We also assume an ideal coherent receiver that detects a channel´s full optical field. We show that the system required OSNR can still be significantly reduced with combined multidimensional modulation and large-overhead FEC
