Abstract :
In this paper we investigate the impact of intra-band incoherent crosstalk due to bi-directional WDM cross-connect (OXC) based on arrayed waveguide grating (AWG), tunable Fiber Bragg gratings (FBG) and optical circulators (OC) on the bit-error-rate (BER) performance of a WDM transmission system. This paper reveals that there is a power penalty suffered by the system due to OXC. The limiting values of crosstalk factor for a BER of 10-9 are determined. It is found that the limiting value of AWG crosstalk factor is -30dB for which the penalty is approximately 8.0dB corresponding to a FBG crosstalk factor of -60dB and a OC crosstalk factor of -50dB for a WDM system with four wavelength channels operating as 10Gb/s.
