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 ...
Key aspects of this research include the utilization of Continuous Wave (CW) lasers for generating stable optical signals, modulation techniques for data pattern simulation, and the analysis of synchronization methods to ensure precise BER measurements.
Mar 1, 2015 · In this study, the authors propose an adaptive channel estimation algorithm for asymmetrically clipped optical orthogonal frequency-division multiplexing visible light communication (VLC) systems and analyse its optimal signal-to-noise ratio (SNR) threshold through the simulation experiments.

Bit Error Rate Testing (BERT) is a test methodology where a known sequence of bits is sent through a communications channel and the received bits are compared against the transmitted bits to determine what percentage of data is being communicated correctly.
