    摘要: A monomode optical transmission fiber with a tapered end portion. A lens is arranged on the end portion. The lens has a refractive index higher than that of the fiber core. Such a fiber has a substantially better coupling efficiency from a diode laser into the fiber core. The lens can be formed by immersing the tapered end portion of the fiber in a transparent liquid material. The drop formed on the end portion of the fiber after withdrawal from the liquid solidifies into a lens.

    摘要: A connector for light waveguides comprising a housing and at least one clamping member provided in the housing. The clamping member comprises a base having a V-shaped guide groove extending in the longitudinal direction of the housing. The guide groove receives a light waveguide plug. A pressure element is provided opposite the guide groove. The pressure element consists of a clamping bridge and pressure members acting thereon. The height of the pressure members is smaller than the distance between the engaging surface of the clamping bridge and the wall of the housing extending opposite the engaging surface. Screw caps are provided to be screwed laterally on the housing and to act on the pressure members via a pressure piece. The pressure members consist of individual balls which have the same diameter and which are provided in at least one row, one behind the other, in the direction of the longitudinal axis of the housing. The balls are provided within a longitudinal groove of the clamping bridge and/or the wall of the housing.

    摘要: A transparent optical distribution system which is tolerant to system variations and extension in future, such as the choice of analogue or digital signals, bandwidth, bit rate, the number of services and connections per subscriber comprises a common terminal unit (3) provided at each subscriber's premises. The common terminal unit (3) comprises an input (100) connected via a power splitter (4) to a distribution box (40) which has a plurality of outputs (45-49) each connected to a respective wall socket (20-24). A second distribution box (50) has a plurality of inputs (55-59) to which the wall sockets (20-24) are connected and outputs (51-54) which are connected via a power splitter (5) to the input (100) of the terminal unit (3). A third distribution box (60) has a plurality of terminals (66-70) connected to the wall sockets (20-24) and a further plurality of terminals (61-65) connected to a power splitter 6 whose output is connected to a mirror (7). Intercommunication between terminals (I-IV) takes place via the third distribution box (60) and is independent of incoming and outgoing signals.

    摘要: The device comprises a transducer (3) comprising a row of photoelectric elements (27), and a coupling member (7) with an entrance (11) which is to be directed towards the document (1) and an exit (13) which is coupled to the transducer. The coupling member is constructed as an integrated optical waveguide circuit comprising a glass substrate (17) in which there are provided grooves (19) which, in order to form optical conductors (21), are filled with a glass having a refractive index which is higher than that of the glass of the substrate. The width of each groove gradually decreases from the entrance of the coupling member towards the exit and over the entire length of the grooves the distance between every two adjacent grooves is substantially constant and substantially smaller than the width of the grooves, so that substantially all light originating from a scanned line of the document is supplied to the transducer.
