Abstract :
We experimentally investigate the fiber-Bragg grating (FBG)-induced group-delay ripple (GDR) mitigation capability of coherent receivers. We also show that 112-Gbit/s DP-QPSK systems with electronic-dispersion compensation (EDC) and FBG-based devices provide similar performances over 840-km transmission.
