Simulation of Undersea Optical Communication System using DCF and SSF

Optical fiber is the link and the backbone of the communication system. This is especially where fiber optic undersea is found low loss, high efficiency and large effective area major for enabling system to transmit big data up to thousand kilometers with less distortion. In this paper, we designed 220 Km fiber optic system with data rate 40 Gb/s in the term of two scenario: the first scenario used fiber optic cable with 80 μM core diameter and the second scenario used optic fiber cable with 17 μM core diameter which made the transmission signal for long distance very difficult. Observing the first scenario, the signal transmitted with less dispersion and less bit error rate 2.956*10

over 220 Km. the signal transmitted over 220 Km with high chromatic dispersion in the second scenario. To avoid chromatic dispersion using, an ideal dispersion compensation FBG, was used to reflect the undesired signal. The received signal on the other side with bit error rate of 4.8625*10
