Receiver sensitivity is the lowest optical power level at which an optical receiver can successfully decode data with acceptable bit error rates (BER). It's a core parameter in optical transceiver specifications, indicating the module's capability to detect weak incoming signals. What Is BER? The bit error rate (BER) measures the data transmission precision within.
