Interface indicators of the SFP module
1. Output optical power refers to the output optical power of the light source at the transmitting end of the module.
2. Received optical power refers to the received optical power at the receiving end of the module.
3. Receive sensitivity refers to the minimum received optical power of SFP module at a certain rate and bit error rate. Under normal conditions, the higher the rate, the worse the receiving sensitivity. The larger the minimum received optical power, the higher the requirement for the receiving device of the optical module.
4.Saturated optical power, also known as light saturation, refers to the maximum input optical power at a certain transmission rate while maintaining a certain bit error rate (10-10~10-12).
