Abstract
A bidirectional optical transceiver module with a temperature control function is provided. The bidirectional optical transceiver module includes a package configured to have a flat bottom surface and include two windows used for optical transmission and reception; a ferrule configured to be coupled to one side of the package and allow an optical fiber to be inserted therein; an optical receiver module configured to be coupled to another side of the package in a direction perpendicular to that of the ferrule coupled to the package; a sub-optical transmitter module configured to be built in the package and include a light-emitting element and a collimating lens used to collimate light from the light-emitting element; an optical filter configured to be built in the package, transmit light from the light-emitting element to the optical fiber and reflect light received through the optical fiber to the optical receiver module; and a temperature regulator configured to be built in the package and control the sub-optical transmitter module to a preset temperature. Accordingly, it is possible to reduce the manufacturing cost of the package, effectively discharge heat, and be more endurable to external impact or vibration.
