  Hi guys! I am working to achieve plausible BERs and good constellations for CO-OFDM transmission upto 1800 km of SSMF using hybrid amplification, yours suggestion required.

  You could start with the example file attached (it can also be found in your OptiSystem Samples folder) and work from there. In [1], they get 1000 km of propagation with a BER of 10-3, although they don’t really describe their amplifier setup. Also their multiplexing format is not exactly OFDM.
