Abstract
An apparatus, circuit arrangement and method enable a host system to read a signal that is proportional to the peak-to-peak optical power incident on a transceiver at one end of a fiber optic link without breaking that link. By reading this signal and being aware of the characteristics of the laser, the “health” of the laser is known and the integrity of the link is maintained. Consequently, the host system has a predictive tool that is able identify substandard lasers so that such lasers can be replaced before serious, and potentially costly, data disruptions occur.
