100M optical module light receiving sensitivity
Receive sensitivity defines the minimum optical power required to maintain an acceptable bit error rate (BER †1E-12) at specific data rates. This parameter depends on multiple technical factors including photodetector type (PIN/APD) and transimpedance amplifier (TIA) noise. When it comes to evaluating the performance of an optical transceiver, two key factors come to the fore: Output power (TX Power) and Receiver Sensitivity (RX Sensitivity). An understanding of these concepts is pivotal to establishing an effective and efficient optical network. It specifies a module's capability to perform in harsh environments and helps network operators determine the maximum reach or link margin available in the system. For example, SONET specifies that the BER must be 10 -10 or better. Overload optical power, also known as saturated optical power, refers to the maximum input average optical power that the receiving.
