Abstract

This paper presents a comprehensive study of the architecture of reconfigurable optical add drop multiplexer (ROADM). Several architectures are introduced for ROADM based on optical switch (OSW), fiber Bragg grating-optical circulator (FBG-OC), digital switch and optical coupler. The performance of the designed architectures is compared by different low input transmission powers with channel spacing of 0.8 nm at 40 Gbps. The signal is transmitted successfully to a distance of 75 km with existing fiber nonlinearities and without using any dispersion compensating techniques or optical amplification. It is shown that better quality factor and least BER is achieved using digital switch and the worst case is found with the optical coupler. The digital switch has been selected as a promising switching element to build the basic reconfigurable optical add drop multiplexer..
