Patent ID: 7160034

Claim:
An optical transmission and receiver module comprising: at least one light emitting device for emitting light having a first wavelength which is to be incident on an optical transmission medium; at least one light receiving device for receiving light emitted from said optical transmission medium and having a second wavelength different from the first wavelength; an optical path routing element for converging the optical path of light having the first wavelength and the optical path of light having the second wavelength on the optical transmission medium side and for separating the optical path of light having the first wavelength on the side of said at least one light emitting device and the optical path of light having the second wavelength on the side of said at least one light receiving device in the directions of said at least one light emitting device and said at least one light receiving device, respectively; a lens transparent to both of light having the first wavelength and light having the second wavelength, the lens being provided between said optical transmission medium and said optical path routing element; a pole for supporting the optical path routing element; and a bench for mounting the pole; wherein the pole is disposed in a space between the at least one light emitting device and the at least one light receiving device.
