摘要： PROBLEM TO BE SOLVED: To obtain the optical transmission and reception module which has a blocking and terminating function (wavelength selective terminator function) for test light inside by providing a wavelength selecting element which demultiplexes inputted signal light and the test light, and then transmits the signal light and reflects the test light with inputted port. SOLUTION: The optical transmission and reception module is divided into a two-way optical transmitting and receiving circuit 1 which transmits and receives 1.3 μm signal light and a WDM circuit 2 which multiplexes and demultiplexes 1.3/1.55 μm signal light and 1.65 μm test light. The WDM circuit 2 consists of optical waveguides 15-1, 15-2, and 16 and dielectric multi-layered filters 21 and 22. The filter 21 transmits the 1.37 μm signal light inputted through the optical waveguides 15-1 and 15-2 to a Y-branch waveguide 11 and reflects the 1.55 μm signal to the optical waveguide 16. The filter 22 reflects the 1.65 μm test signal inputted from the optical waveguide 15-1 to the optical waveguide 15-1 and transmits the 1.3/1.55 μm signal light to the optical waveguide 15-2.

摘要： PURPOSE:To provide an optical fiber with a rod lens which is producible at a low cost by using a multimode optical fiber which is cut into a prescribed length to provide the fiber with a light condensing function as a rod lens without impairment of the ease of an assembling operation and using a capillary which is a generally marketed product without using a ferrule of special specifications. CONSTITUTION:This optical fiber with the rod lens consists of the single mode optical fiber 1, the rod lens 2 formed by cutting the multimode optical fiber 2' into a prescribed length to provide the fiber with the light condensing function and the capillary 3. The rod lens 2 is brought into contact with the front end of the single mode optical fiber 1 and is inserted and fixed in this state into the hole of the capillary 3 to make the rod lens into an integral structure with the single mode optical fiber 1.

A temporary alignment operation is executed in such a manner that this port comes to an alignment position and thereafter the second port is selected by the operation to select the port which is max. in the compared loss quantity and the alignment position of the second port is determined. The fine adjustment quantity to maximize the min. value of the degree of allowance for the permissible threshold of the light loss quantity is determined by the operation to determine the optimum fine movement quantity in accordance with the deviation quantity of the second port from this alignment position. A fiber arranging means 5 is moved relative to an optical waveguide chip 1 by as much as this fine movement quantity, by which the optical waveguides 13 and the optical fibers 4 are integrally aligned.

摘要： PURPOSE:To improve the positioning accuracy of optical fibers by irradiating the optical fibers with UV rays by using a means for increasing the intensity of the UV rays to be cast near to the optical fibers. CONSTITUTION:The coated optical fibers 13 and an optical fiber ribbon 14 are arranged in a molding flask and a UV curing resin is packed into the block molding region between this molding flask and the optical fibers. The UV rays are then radiated from a UV source 15 and the UV curing resin packed in the flask is irradiated simultaneously with the UV rays for five minutes from two directions; the upper surface of an upper cap 11 and the back surface of a lower flask 12. The UV curing resin is cured by irradiation with the UV rays. The difference in the intensity of the UV rays generated between the packed resin near the optical fibers and the packed resin around the molding flask is decreased by the simultaneous irradiation of the packed UV resin from the two directions in such a manner and, therefore, the delay in curing of the packed resin near the optical fibers is relieved or eliminated and the strains concentrating to the packed resin near the optical fibers is relieved or eliminated.
