ABSTRACT:
Provided are a multi-wavelength optical transceiver module and a multiplexer/demultiplexer using a thin film filter. The multi-wavelength optical transceiver module includes: a PLC platform, on which a predetermined optical waveguide unit is formed and an optical transmitter is mounted; an optical fiber coupled to one side of the PLC platform to transmit a predetermined light; a plurality of thin film filters coupled to another side of the PLC platform to separate input optical wavelengths; and an optical receiver coupled to one side of the thin film filters to receive light that is input from the optical fiber and transmits the thin film filters, thereby enabling mass production of the optical transceiver module with low cost.
