Abstract
AbstractIn this work, a suppression method of Four wave mixing (FWM) is proposed using optical phase conjugation (OPC) and different placements of OPCs are also investigated. Moreover, comparison of the placements of OPC in two different cases has been done and compared with conventional wavelength division multiplexing system in terms of Q factor, bit error rate (BER), and induced FWM. Analysis has been done at different link lengths, launched powers levels, and laser line widths. It is observed that placement of OPC after laser source performs exceptionally well and suppresses FWM with ease of maintenance.
