Abstract :
In this paper, we analyse the theoretical performance of uncompensated optical transmission system using Gaussian Noise (GN) model considering the effect of amplified spontaneous emission (ASE) noise summation and the generation of nonlinear interference (NLI) noise due to the erbium doped fibre amplifier (EDFA) and the number of channels. We optimize the optical SNR (OSNR) for computed NLI and ASE noise on coherent uncompensated optical transmission systems (CUOTS) considering four different commercial optical fibre types (SSMF, PSCF150, LEAF, and SMFULL). The bit error rate (BER) is computed for obtained OSNR considering PM-BPSK, PM-QPSK, and PM-16QAM modulation formats where each format runs at 32 GBaud symbol rate.
