Abstract

Using WDM multiplexing is one of the ways to increase PON bandwidth. But as WDM-PON is still expensive and difficult administered, the idea of using a Reflective Semiconductor Optical Amplifier (RSOA) is proposed. It can be installed in WDM-PON ONU network devices. A comprehensive problem analysis of various investigations is done relating to a performance of RSOA-based WDM-PON systems. The simulation model is created for RSOA-based WDM-PON access with downstream signal reusing in ONU for upstream transmission. This model helped in researching of RSOA abilities using different downstream and upstream signals modulation. Signal parameters were tested working with special software OptiSystem. Results were evaluated regarding such a characteristics as Q factor, signal attenuation, power and optical fiber length. It was found that RZ code was better suited in remodulation with RSOA; it achieved 1.25 Gbps signal transmission at a distance 8 times larger than that of the in NRZ code case.
