A Power Compensated Novel Architecture of RM-OXC Based on T-FBG and OC: A High-speed and Cost-effective System

Abstract

Abstract This paper presents a high-speed, power-compensated novel architecture of N×N reconfigurable multiwavelength optical cross connect (RM-OXC) based on tunable fiber Bragg grating (T-FBG) and optical circulator (OC). FBG and OC-based OXCs are network elements that play a significant role in optical networks to offer more network survivability and reconfiguration flexibility. Optical signal-to-noise ratio of 71.05, 69.05 and 67.05 dB is achieved with acceptable quality factor of 7.54, 6.95 and 6.41, respectively, with 10 Gbps having input transmission power of −8 dBm at different transmission distances (40, 50, 60 km). It is found that the signal is communicated to a maximum distance of 60 km in the presence of fiber nonlinearities without optical amplifier at 0.8-nm channel spacing.
