Performance evaluation of SCM–WDM communication in the presence of SRS induced crosstalk for different types of fiber

Abstract

In this paper, the SRS-induced crosstalk has been evaluated in a SCM–WDM communication link at different modulation frequencies for various type of fibers. Results show that SRS-induced crosstalk dominates at low frequency. As the dispersion and effective area of fiber ( A eff) decreases, initially the crosstalk remains high and then it decreases with increase in modulation frequency. The present work shows that out of five different types of fibers, Standard Single Mode Fiber (SMF) has minimum crosstalk (−53 to −64 dB) and True Wave fiber (TW) has maximum crosstalk (−47 to −48 dB).
