Bit Error Rate (BER) testing is a crucial aspect of evaluating the performance of digital communication systems. It involves measuring the rate at which errors occur in a transmitted bitstream compared to the expected bitstream at the receiver end. The BER measurement helps in assessing the quality. Bit Error Rate (BER) is a critical performance metric in optical communication systems, representing the ratio of erroneous bits to the total number of transmitted bits. As optical links are increasingly used for high-speed data transfer, understanding and managing BER becomes essential to ensure.
