摘要： In a optical transmitting and receiving module ,a transmitting light beam having a wavelength 1 emitted from a light-emitting device (6) passes through an optical demultiplexing filter (5) and enters an optical fiber is reflected from the optical demultiplexing filter and is incident on a light-receiving device. A cover (40) for covering the front space of the optical demultiplexing filter is placed on a casing block (20), and a tongue piece (41) serving as a returning-light preventing unit is formed on the cover. When a transmitting light beam emitted from the optical demultiplexing filter, the direction in which the reflected light advances is changed by the tongue piece so that the reflected light is not incident in the light-receiving device.

摘要： The optical communication system comprises at least one transmitter (Tx1, ... Txn) provided with a light source (10) for emitting white light having a wide wavelength band (λ1, ... λn), an optical fiber (2) for transmitting white light emitted from the light source and at least one optical switch (21,22) placed along the optical fiber, and at least one received (Rx1, ... Rxn). The optical switch has an optical filter (115,125) for selectively splitting predetermined different wavelengths and reflecting other wavelengths, and a switching device for cutting off or passing lights of the wavelengths split by the optical filter. An optical filter merges light transmitted by the switching device with lights of other wavelengths reflected by the optical filter and transmits it to the optical fiber.

摘要： Disclosed herein is an optical communication connector. A connector (100a) optically couples between a pair of plastic fibers (F11a, F11b) and a pair of silica fibers (101a, 101b), and a connector optically couples between the other ends of the silica fibers and a pair of plastic fibers. In such a construction, signal light is bidirectionally transmitted using these fibers. The connector is provided with one condenser lens (120) within a casing. On the side of the transmission of signal light from the silica fiber to the plastic fiber, end surfaces of both cores P and Q are brought into intimate contact with each other. On the side of the transmission of signal light from the plastic fiber to the silica fiber, end surfaces of both cores P and Q are opposed to each other with the condenser lens interposed therebetween. The other connector is also constructed in a manner similar to the above connector.
