How to evaluate optical through bit error rate BER in dB?
The BER may be improved by choosing a strong signal strength (unless this causes cross-talk and more bit errors), by choosing a slow and robust modulation scheme or line coding scheme, and by applying channel coding schemes such as redundant forward error correction codes [2].
Abstract—In telecommunication, the Bit Error Rate (BER) is an indication of how often data has to be retransmitted because of an error. The different modulation techniques scheme is suggested for improvement of BER in fiber optic communications. The developed scheme has been tested on optical fiber systems operating with a non-return-to-zero ...
The study focuses on the critical factors influencing BER, including optical power levels, attenuation, dispersion, noise, transmission distances, and component quality. Through OptiSystem simulations, various BER measurement techniques such as eye diagrams, Bit Error Rate Testers (BERTs), and 2D graphs are employed to evaluate system ...

New system concepts including dense wave-length division multiplexing (DWDM) and optical time division multiplexing (OTDM) have multiplied the transmission capacity of an optical fiber. Especially WDM provides a straightforward way to upgrade the capacity of the existing fiber lines.
The root cause of this problem could be with the fiber optic link wherein bit errors are being introduced by a poorly cleaned connector, for example, or a cable that is physically crushed at an unknown point in between the two buildings.
