Link fault management for optical adapters

An apparatus for optical link fault management includes a processor in a network device with an optical adapter of an optical link, and a memory that stores program code. The program code is executable by the processor to store state parameters from the optical adapter in a data log, input the state parameters from the data log into a failure prediction model, and generate, using the failure prediction model, a probability of failure of the optical adapter based on current state parameters from the data log. In response to the probability of failure reaching a failure threshold, the program code is executable by the processor to decrease data traffic in the optical link and to send an alert comprising the probability of failure. The failure threshold includes a probability of failure indicative of impending failure of the optical adapter.
