XPM-induced crosstalk with variety of fiber in SCM–WDM optical transmission link

Abstract

In this paper, XPM-induced crosstalk has been evaluated in a SCM–WDM communication link at different modulation frequencies, transmission lengths and optical powers for variety of fiber. Results show that XPM-induced crosstalk dominates at high frequency. As the dispersion and effective area of fiber (Aeff) decrease, crosstalk increases with increase in modulation frequencies, transmission lengths and optical powers. The present work shows that out of five different types of fiber, Standard Single Mode Fiber (SMF) has minimum crosstalk (−78 to −38)dB, (−55 to −33)dB and (−46 to −34)dB at modulation frequencies, transmission lengths and optical powers. Dispersion compensation fiber (DCF) has maximum crosstalk (−60 to −12)dB, (−37 to −12)dB and (−27 to −12)dB at modulation frequencies, transmission lengths and optical powers.
