In this paper, we investigate the effect of crosstalk of three types of optical cross connects based on Mach-Zehnder Interferometer( MZI), MZI-Semiconductor optical amplifier (SOA) and MZI-Fiber Bragg gratings (FBG) techniques obtained at 4x10 Gbps with 0.1nm channel spacing wavelength division multiplexing transmission with 2x2 optical cross connects using standard single mode fiber. The influence of increase in length of fiber has been investigated to evaluate the performance of optical communication system. It is found that the signal can be transmitted with minimum BER using MZI-FBG based OXC and MZI based OXC up to 80 Km whereas, the MZI-SOA based OXC provides poor performance. The input-output power relationship shows improvement up to -14 dBm approximately in output power for MZI based OXC and MZI-FBG based OXC. It is observed that the MZI Based OXC architecture is cost effective as compared to MZI-SOA and MZI-FBG Based OXC architectures..
