Abstract
The present invention provides a transceiver module having advantages of minimizing the number of optical parts by using an optical collimator to which a lens having the same shape as a diameter of an optical fiber is attached on a light input/output end. An transceiver module according to the present invention includes, laser diode for generating an optical signal to transmit, a first photodiode for controlling the laser diode, a second and third photodiodes for receiving an optical signal of a first and second wavelengths, and an optical collimator formed at a light input/output end. On the optical collimator, a lens having an optical fiber shape is attached in a direction the light proceeds.
