Abstract

Abstract This paper investigates the impact of coherent and incoherent crosstalks on bit error rate of a multihop wavelength division multiplexing (WDM) transmission system with limited-wavelength-interchanging cross connects (L-WIXCs). The relation between the crosstalk and signal to crosstalk plus noise ratio at the receiver output is analyzed and redefined with an improved mathematical modeling. Quantitative analysis of the bit error rate (BER) in terms of system parameters like number of hops, number of fiber and number of wavelength channels per fiber are evaluated. The power penalty due to accumulated crosstalk at a given BER of 10−9 and the optimum system design parameters are also determined numerically. Results show that there is a significant power penalty of the order of 10–12 dB due to accumulated crosstalk depending on the number of hops. Maximum allowable number of hops at a given BER of 10−9 and number of input fibers are also evaluated.
