Performance Evaluation of All Optical 2R Regenerators Based on Four Wave Mixing

Merlin Philip, Pratheesh P.

Abstract: An optical signal propagates through a transmission link comprised of fiber and various components, the signal becomes degraded by various impairments such as Amplified spontaneous emission noise, dispersion, and fiber nonlinearities. In order to transmit the optical signal at longer distance, the signal should be regenerated in the intermediate nodes by cleaning up the accumulated noise and distortion. An all optical regenerator is an effective way to overcome these limitations. In this paper, All optical 2R regenerator is designed based on four wave mixing. The performance of regenerator is analyzed using power transfer function, BER measurement etc. The 2R and can be simulated using a commercial optical system simulator named OptiSystem 12.0 by Optiwave.
