Abstract
The use of coherent detection in optical fiber communications offers advantages of increased signal transmission capacity, improved receiver sensitivity, and flexibility of system design. This paper describes the practical limits to coherent digital system performance and design considerations to a 140 Mb/s FSK digital system. Despite the recent advances made in various research laboratories, coherent fiber optic systems are still in the infancy stage, largely attributed to the lack of components needed to realize the ultimate performance which coherent technology can offer. In this paper, the factors affecting performance degradation are identified and the relative significance of each factor is examined.
