Receiver sensitivity in dBm equals the thermal noise floor plus the noise figure plus the minimum required SNR: Sensitivity = -174 + 10·log10 (B) + NF + SNR_min. Compute thermal noise floor (kTB) from. In optical communication systems, sensitivity is a measure of how weak an input signal can get before the bit-error ratio (BER) exceeds some specified number. The standards body governing the application sets this specified BER. Exceeding the BER value indicates signal degradation, rendering it unsuitable for data communication.
