Efficient Routing Strategies of N × N RM-OXC Using C Band Based on T-FBG and OC

Abstract

Abstract A novel architecture of N×N reconfigurable multiwavelength optical cross-connect based on tunable fiber Bragg grating (FBG) and optical circulator is proposed. The effect of cross talk in dense wavelength division multiplexing system with 0.8-nm channel spacing at 9×10 Gbps is also evaluated. Optical signal to noise ratio achieved is 40.95 dB at input transmission power of −10 dBm with acceptable bit error rate, i.e. 1.16×10−10at −30 dB FBG cross talk in the presence of fiber nonlinearities. It is found that signal is transmitted to a distance of 50 km without optical amplifier.
