Title:
OPTICAL TRANSCEIVER CAPABLE OF CONTROLLING SELF-HEATING ACCORDING TO TEMPERATURE
Document Type and Number:
WIPO Patent Application WO/2013/065989
Kind Code:
A1
Abstract:
The present invention relates to an optical transceiver capable of controlling self-heating according to temperature, and more particularly, to an optical transceiver which uses a PTC heater suitable for temperature characteristics to easily control self-heating. According to the present invention, a PTC heater, the self-resistance of which 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.
