Fluctuation in the received power of the optical module
Fluctuating optical power often results in: Common root causes include connector contamination, bending loss, or poor mechanical contact. 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. The transmit optical power of an optical module is in the normal range, but many packets are dropped due to bit errors on the optical interface. Industry pundits have recently speculated that demand for 100G/400G switches may take off in 2019, prompting optical transceiver module vendors to sample data center switches with high data transmission rates earlier than expected. Overload optical power, also known as saturated optical power, refers to the maximum input average optical power that the receiving.
