    Abstract: PURPOSE: A bidirectional optical transceiver module is provided to prevent link failure of optical communication networks due to reflection and back-scattering in an optical path. CONSTITUTION: A splitter (120) outputs a transmission signal to the outside to transmit the transmission signal. The splitter receives and reflects an optical signal inputted from the outside. A reflective light cut-off optical filter unit (140) a reflective signal including at least one selected in the internal reflective signal and external reflective signal inputted to an optical reception unit in the reflected optical signals. The reflective light cut-off optical filter unit passes an optical signal within a predetermined wavelength range including the allocated wavelength value to the reception signal as a reception signal. The reflective light cut-off optical filter unit cuts off external reflective light. [Reference numerals] (AA) Transmitting signals; (BB) Receiving signals

    Abstract: PURPOSE: An optical transceiver capable of controlling self-heating according to the temperature is provided to use a PTC(Positive Temperature Coefficient) heater suitable for temperature characteristics in order to easily control self-heating of the optical transceiver, thereby significantly reducing 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. CONSTITUTION: An optical transceiver(100) comprises a laser diode, a stem body, a PTC heater(130), and a laser driver(140). The stem body is coupled with the laser diode. The PTC heater is coupled with the stem body and generates heat. The laser driver drives the laser diode. The coupling of the stem body and the PTC heater is carried out by inserting lead pins into multiple holes formed on the PTC heater or by applying adhesives on the surface of the stem body or on the rear side of the laser diode.
