The importance of predicating failure of optical transceiver becomes more and more critical due to the high cost of lost traffic in the networking infrastructure. After Facebook’s massive deployment of 100G CWDM4, we are reporting one mechanism that will allow us to predict the optical transceiver failure. This is based on the investigation of the relationship among the bias current of the laser diode, transmitter power degradation and environmental changes. This mechanism will eventually be embedded into the firmware of the transceiver to provide us a guide to pull the problematic transceiver out of the networking before it actually fails.
