HEAT TRANSFER DEVICE FOR PLC MODULE

摘要

PURPOSE: A heat transfer device for PLC(Planar Lightwave Circuit) module is provided to prevent a lowering phenomenon of the quality of optical signals due to a temperature difference between a PLC and an optical fiber block by maintaining uniformly the temperature of the PLC and the optical fiber block. CONSTITUTION: A PLC module includes a PLC(310), an input optical fiber block(301a) connected to an input terminal of the PLC(310), and an output optical fiber block(301b) connected to an output terminal of the PLC(310). A heat transfer device for PLC includes a heat transfer plate(370) and a heat generator(390). The heat transfer plate(370) is adhered on entire surfaces of bottoms of the input optical fiber block(301a) and the output optical fiber block(301b). The heat generator(390) is adhered on a bottom face of the heat transfer plate(370).
