Crosstalk and channel spacing in a coherent multichannel system using erbium doped fibre amplifiers

The influence of optical amplification with an erbium doped fibre amplifier (FDFA) on coherent multichannel (CMC) transmission is investigated experimentally. The authors found that exactly the same crosstalk/signal ratio can be tolerated in a CMC-system with and without EDFA. They observed no noise floor nor other effects caused by spectral broadening due… CONTINUE READING
