Reasons for overheating of fiber optic AP panel

Heavy data traffic, poor heat dissipation, high ambient temperature and component aging easily overheat optical transceiver, resulting in signal degradation, higher bit error rates, shorter transmission distance and even module failure. While they're designed to operate within specified temperature ranges, running a module above its rated operating temperature causes measurable performance degradation and can lead to permanent failure. This article explains what goes wrong, why it matters, and practical steps engineers and. Thus, the conjugation of high power propagation and tight bending, resulting from the actual FTTH infrastructures, is responsible for fibre lifetime reduction, mainly caused by the local increase of the coating temperature.
