A method including determining, for a given hardware link, whether a signal error rate for signals sent over the given hardware link is beyond a given threshold, when the signal error rate is beyond the given threshold, generating an error indication for the given hardware link, the error indication including a prediction that a hardware component associated with the given hardware link is likely to fail. Related apparatus and methods are also provided.

Failure prediction system and method

Methods and devices for laser driver calibration are disclosed. The methods and devices disclose determining first and second bit error rates for use in calibrating the laser driver. The methods and devices also disclose that if the first bit error rate associated with a first initial value is above a predetermined bit error rate, increasing the first initial value until the first bit error rate is not above the predetermined bit error rate, and if the second bit error rate associated with a second initial value is above a predetermined bit error rate, decreasing the second initial value until the second bit error rate is not above the predetermined bit error rate. In addition, the methods and devices disclose setting a calibrated parameter for the laser driver based, at least in part, on the increased first initial value and the decreased second initial value.
