The four-channel WDM system using Semiconductor Optical Amplifier

This article focuses on the creation of a four-channel WDM (Wavelength Division Multiplexing) system using SOA (Semiconductor Optical Amplifier) at the speed of 10 Gbps and the spacing of 1nm. In creating an optical network it is necessary to utilise software tools simulating a real optical network under the given conditions. Evaluation of the optical line quality for the respective channel is performed on the basis of BER (Bit Error Rate). The result of the article is a WDM system in a simulated environment evaluating BER at particular stream in SOA. The wavelengths compared were of 1549 nm and 1550 nm at pump current in the SOA: 0.05 A, 0.1 A and 0.2 A.
