Performance Analysis of Dispersion Compensation Schemes with Delay Line Filter

Abstract

Optical communication is an effective system to achieve the high-speed data transmission for long distance. The main factor that affects the optical communication is dispersion. Dispersion leads to reduction of the system performance and Q-factor. Dispersion can be compensated using various techniques. Major techniques are compensation using Dispersion Compensating Fiber (DCF), Fiber grating technique, and Delay Line Filter (DLF). Analysis has been performed on the Bit Error Rate (BER) and Quality Factor (Q-Factor) of various schemes based on Eye Opening Penalty (EOP) with BER analyzer for dispersion compensation. It has been concluded that Impulse Invariant Response (IIR) based DLF at average results in 50% of better compensation when compared Fiber Bragg Grating and DCF based compensation techniques. The power of the received signal when transmitted at 0 dBm for 120 kms is-12.325 dBm which is the optimum power in which the signal can be received without distortion.
