“…BER and related Q factor BER depreciates in the case where the decisive level extends beyond the interference -which then results in an incorrect interpretation of received optical impulses. In practice, the optical line is delivered to the network provider with a complete documentation and with the individual values of BER evaluating individual lines (BER representing the criteria of quality of the line) [29][30]. BER is calculated based on its number of acknowledged faults received in that particular optical signal: ,…”

The continual increase in transfer capacity and speed leads to the continual improvement of fully optical transfer communication systems. The aim of this article is to present the creation of an 8-channel CWDM (Coarse Wavelength Division Multiplex) system (gap spacing of 20 nm), where 10 channels, with gaps of 2 nm are gradually inserted between wavelengths of 1530 nm to 1550 nm according to the ITU-T G.694.1 recommendation. This system is evaluated using the BER (Bit Error Rate) of a specific channel operating on a wavelength of 1540 nm. In the topology we used an EDFA (Erbium Doped Fibre Amplifier) placed In-Line at 90 km with a bit speed of 10 Gbit.s-1. Consequently, in order to overcome the problem of distance, an optical loop with an appropriate EDFA configuration was created. This article presents the basic mathematical description of bit error rate and also deals with the possibility of the incorporation of CWDM and DWDM systems into existing infrastructures.
