Abstract:
A light transmitting/receiving module comprising:a planar platform having a top surface, a bottom surface, sides, a front end and a rear end; a straight light guide formed on the top surface of the platform in a direct line starting from the front end for guiding transmitting light and receiving light with an end appearing at the front end of the platform; a photodetector (PD or APD) mounted just above the light guide for detecting power of receiving light; a slanting groove formed close to the photodetector (PD or APD) on the way of the light guide on the substrate; a filter being inserted into the slanting groove and sloping upward for reflecting receiving light, introducing the reflected light to the photodetector (PD or APD) and penetrating transmitting light; a light source (LD or LED) being positioned at an extension of the light guide on the platform for introducing transmitting light to the light guide; V-grooves formed on the top surface from the front end of the platform; and guide pins fixed in the V-grooves for temporarily connecting to an optical connector having a front end, an optical fiber appearing at the front end, and holes perforated at the front end by inserting the guide pins of the module into the holes of the optical connector and positioning the fiber end opposite to the light guide end and for temporarily separating the optical connector by extracting the guide pins from the holes of the connector.
