Investigation on four wave mixing effect in various optical Fibers for different spectral efficient orthogonal modulation Formats

摘要

The paper analyzes the four wave mixing (FWM) effect in different spectral efficient orthognal modulation formats at equal channel spacing of 100 GHz and 50 GHz to design long haul wavelength division multiplexing (WDM) optical system. Further, the comparison of reduction of FWM for existing and proposed modulation format have been analyzed by varying the laser input power from -10 dBm to 10 dBm. (C) 2015 Elsevier Ltd.
