Abstract
Disclosed is an optical transceiver capable of controlling self-heating according to temperature, more particularly, an optical transceiver which uses a PTC heater suitable for temperature characteristics to easily control self-heating. A PTC heater of which the self-resistance changes depending on the ambient temperature of uncooled laser diodes of an optical transceiver so as to adjust heating volume of the heater, is applied to a TO CAN, thus making it possible to significantly reduce power consumption while expanding an available temperature range of existing optical modules, even without a separate controller or using a minimum number of control circuits.
