Abstract: This article focuses on the simulation of four-channel WDM (Wavelength Division Multiplexing) system with the spacing of 4 nm and the speed of 10 Gbps. It underlines the error rate BER (Bit Error Rate) which changes with the input power of fibre amplifier EDFA (Erbium Doped Fibre Amplifier) for the respective channel of WDM. Nowadays while designing the WDM it cannot be done without software tools simulating a real network to avoid possible mistakes which could occur before the actual construction of communication systems. Simulation solves the creation of WDM from 1554 to 1566 nm with the best error rate for the respective channel using single-mode optical fibre 40 km long with measurable attenuation constant according to ITU-T G-652-D.
