Abstract: The desire for higher per-fibre transport capacities and at the same time, the drive for lower costs per end-to-end transmitted information bit has led to optically routed transmission systems with higher spectral efficiencies. Among other enabling techniques that are used for the purpose, optical modulation formats with the application of some forward error correction techniques have become key to the design of modern optical transmission systems. In this paper we have analysed the optical communication system to evaluate the performance of different modulation formats with or without applying forward error correction techniques.
