Abstract :
The coded modulation schemes enabling 100+ Gb/s transmission by using commercially available components operating at 40 Giga symbols/s have been proposed and discussed in this paper. We considered bit-interleaved coded modulation (BICM) in combination with the low-density parity-check (LDPC) codes that are used as component codes, and in combination with coherent detection scheme. It was shown that coherent detection scheme outperforms the direct detection one and provides additional margin needed for application in an all-optical network scenario.
