Abstract
The OSNR margin improvements due to FEC limit elevation in 112Gb/s PDM-DQPSK systems under two different receiver schemes, direct detection and coherent detection with digital signal processing (DSP), are analyzed.FEC limit elevation provides more benefit to the direct detection scheme than to the coherent detection scheme in 112Gb/s PDM-RZ-DQPSK system.
