What is the sensitivity of an optical receiver
Receiver sensitivity is a critical parameter in optical communication systems, determining the minimum optical power required to achieve a specified bit error rate (BER) or signal-to-noise ratio (SNR). In essence, it measures how well a receiver can detect weak optical signals. For example, SONET specifies that the BER must be 10 -10 or better. This helps you pick the best device. Receiver sensitivity is expressed in dBm.

What is the use of an optical receiver module
An optical transceiver module, often simply called an optical module, acts as a signal conversion interface in fiber optic networks. It's the endpoint of any fiber optic link, sitting at the far end of the cable and translating pulses of infrared light into the ones. That is, metal medium communication represented by coaxial cables and network cables is gradually being replaced by optical fiber media. Its primary function is to achieve optoelectronic conversion by converting electrical signals into optical signals and vice versa. The optical receiver is the direct counterpart to the optical.
