Optical module input power is negative

Home / Optical module input power is negative

An optical module's actual transmit power measured by an optical power meter is lower than the nominal transmit power of the power module. The article Digital Diagnostic Function (DDM) For Optical Modules describes that DDM function can be used for real-time monitoring and fault location of the module's working status, in which the optical module's transmitting optical power and receiving optical power are the key parameters for. Overload optical power, also known as saturated optical power, refers to the maximum input average optical power that the receiving end components can receive under a certain bit error rate of the optical module. My Airtel Xstream Fiber connection's Optical Module Input Power (dBm) has significantly decreased from -24 dBm to -27 dBm. Is it okay or is there a need for concern that some problem with speed and latency will be faced soon? It should be less than -27 dBm at all times otherwise you will have.
