Abstract

This invention relates to a temperature control system for laser diodes, especially for use in optical communication equipment. The system comprises means for limiting the cooling effect in the laser unit when the temperature of the optical transmitter module is higher than a predetermined temperature, or when the cooling power consumed by the thermoelectric cooler is larger than a predetermined power level. In this way, the power consumed in the thermoelectric cooler can be minimized, without this affecting the reliability or lifetime of the laser diode.
