Abstract: Disclosed is a bi-directional optical transceiver module. The bi-directional optical transceiver module includes: an optical transmission unit configured to output a transmission signal; an optical reception unit configured to receive an input of a reception signal, the transmission signal and the reception signal having different wavelength values within a single channel; a splitter installed to be inclined with respect to an incident direction of the transmission signal output from the optical transmission unit to output the transmission signal to an outside and to reflect optical signals input from the outside; and a reflected light-blocking optical filter configured to pass, as a receiving signal, only an optical signal within a preset wavelength range including the wavelength value allocated to the reception signal among the optical signals reflected by the splitter so as to block external reflected light. The present disclosure may prevent a bi-directional optical transceiver module capable of preventing a link fail between optical communication networks according to reflection and backscattering on an optical line.

Abstract: A light guide body which allows a wider incidence angle of light, and which can surely guide light to a desired position is provided. A light guide module 1 includes a semicircular plate-like body portion 1020. In the body portion 1020, a light incident surface 1020A on which infrared rays are incident is formed along a diameter portion. An incident reflective surface 1020B which is disposed inclinedly with respect to the normal direction of the light incident surface 1020A, and which reflects the infrared rays that are incident through the light incident surface 1020A is formed in the diameter portion opposed to the light incident surface 1020A. Arcuate light guiding paths 1212, 1213, 1214, 1215 (1222, 1223, 1224, 1225) which guide infrared rays reflected by the incident reflective surface 1020B to a light emitting portion 1021A (1022A) are formed in the body portion 1020. The light emitting portion 1021A (1022A) is formed so that the longitudinal direction extends along the center line L of the semicircular shape, and reflects the infrared rays guided by the light guiding paths 1212, 1213, 1214, 1215 (1222, 1223, 1224, 1225), toward the back surface side of the body portion 1020.
