Abstract:
In this article, diverse dispersion compensating techniques are demonstrated and also examined their performance in the presence of nonlinearites at different data rates in between 2.5 and 20 Gbps. Dispersion compensation formats such as pre-compensation, post-compensation, hybrid (symmetrical) compensation, Fiber Bragg grating (FBG) and optical phase conjugation (OPC) are used in single-channel light-wave system. The performance is evaluated on the behalf of different parameters such as Q value, Bit error rate (BER) and eye patterns. It is observed that in dispersion compensation, hybrid compensation format gives better results than the other compensation formats. It is also observed that hybrid compensation format is suitable for high data rates up to 20 Gbps while pre- and post-compensation gives better results up to 15 Gbps and FBG and OPC formats covered better results up to 10 Gbps
