Abstract: The paper presents the optimal value of BER by selecting the threshold current. By optimizing the threshold current, we should get the optimal value of BER. The change of the threshold level in the decision device has a great influence on the optimization of the Q=(BER) parameter. The threshold Ith should be chosen so as to minimize the BER. The paper presents a BER= ? (Q) graph where even a small change in Q leads to a significant reduction (improvement) in BER. Performance degradation/disruption of an optical telecommunication system, among other factors, is uniquely dependent on the receiver noise, transmitter intensity noise (RIN), which requires proper design and selection of operating modes considering the operating conditions of the transmission line.

Key words: BER - Bit Error rate; RIN - Relative Intensity Noise; DFOTS - Digital fiber-optic transmission system.
