    摘要: A device for converting light into an electric signal comprises an optical transmission element for transmitting light as well as a photoelectric sensor element (20) for converting light into an electric signal. The optical transmission element has a curved section (BA). The optical transmission element (10) is designed in such a way that light transmitted in the optical transmission element (10) is extracted from the optical transmission element (10) in the curved section (BA). The photoelectric sensor element is disposed in such a way that the light extracted from the optical transmission element (10) is injected into the photoelectric sensor element (20). The photoelectric sensor element is designed such that the electric signal is generated when light is injected into the photoelectric sensor element (20).

    摘要: An optical fiber tap which is especially useful as a node in a local area network, especially a ring topology local area network. The tap, which does not interrupt the physical continuity of the fiber, has an open position and a closed position. In the open position, a signal passing down the optical fiber (14, 122) passes through the tap without alteration. In the closed position, a signal passing down the optical fiber is extracted through a first bend (16) which is put into the fiber by the tap; the extracted signal, or an electrical counterpart thereof, is processed and a counterpart of the extracted signal, or a new signal obtained by operating on the extracted signal, e.g. in a data processor, is injected into the fiber through a second bend (24) which is put into the fiber by the tap. The tap may also contain an attenuator (32) between the signal extractor and injector, so that only that signal injected by the tap propagates down the fiber beyond the tap.

    摘要: Ein optisches Breitband-Nachrichtenübertragungssystem (11) für den Teilnehmeranschlußbereich ist mit einem bidirektional betreibbaren Lichtwellenleiter (12), in dem in einem Wellenlängenbereich der deutlich unterhalb seiner Grenzwellenlänge liegt, nur der Grundmodus LP01 und der nächst höhere Modus LP11 ausbreitungsfähig sind, ferner mit zwei optischen Sendern (16,18) und mit zwei Empfängern (17,18) und mit zwei Empfängern (17,19) versehen, deren Betriebswellenlänge in dem genannten Wellenlängenbereich, in dem der Lichtwellenleiter (12) betrieben werden soll, liegt, wobei die optischen Sender (16,18) und die optischen Empfänger (17,19) so an den Lichtwellenleiter angekoppelt sind, daß zwei optische Signale bidirektional mit unterschiedlichen Moden LP01 , LP11 übertragen werden. Um bei einem derartigen optischen Breitband-Nachrichtenübertragungssystem (11) eine einfachere und kostengünstigere Ausführung zu erreichen, ist vorgesehen, daß der eine optische Sender (16) Signale im LP01-Modus in den Lichtwellenleiter (12) einkoppelt und die Signale dieses LP01-Modus durch Abstrahlung zum einen optischen Empfänger (19) ausgekoppelt sind und daß der ander optische Sender (18) und der andere optische Empfänger (17) jeweils einer im Zuge des Signals im LP01-Modus führenden Lichtwellenleiter (12) angeordneten Ein- bzw. Auskoppel-Vorrichtung (23,22) zugewandt ist, die dazu dient, Signale im LP11-Modus vom anderen optischen Sender (18) in den Lichtwellenleiter (12) einzukoppeln bzw. aus dem Lichtwellenleiter (12) zum anderen optischen Empfänger (17) hin auszukoppeln.

    摘要: A handtool for detecting whether or not an optical fibre F is carrying a light signal includes a motor-driven operating mechanism mounted in the tool housing (1) for causing a pressure member (9) to move towards or away from an anvil (4) so that when the pressure member is caused to move towards the anvil an optical fibre positioned between the pressure member and the anvil will be subjected to microbending of a gradually increasing extent. The motor-driven operating mechanism preferably comprises a screw-threaded shaft (12) supported in the housing (1) and rotatably driven about its axis by the motor (14) in either rotational direction.
    This application is directed to a modification of the apparatus for detecting whether or not an optical fibre is carrying a light signal forming the subject of co-pending European Patent.

    摘要: Apparatus for handling an optical fibre (13) comprises a casing (1) defining a substantially light-proof enclosure surrounding an optical fibre operating position, and mechanical means (4 to 8) for picking up an optical fibre and transporting that optical fibre to the operating position. The operating position is defined by a secondary waveguide (2) which defines a curved optical waveguiding path. The mechanical means (4 to 8) is such as to position the optical fibre (13) in a curved position which at least substantially conforms to the inner side of the curved optical waveguiding path, whereby optical energy passing along the optical fibre is tapped into the curved optical waveguiding path.

    摘要: Jaws of a microbend sensor have corrugations and hold an optical fibre (5) therebetween. The jaws (2ʺ, 3ʺ) are movable with respect to one another for squeezing and bending the optical fibre (5) between the corrugations. The amount of bending modulates light passing through the optical fibre (5) which can be detected to provide a measurement of the relative movement between the jaws (2ʺ, 3ʺ). The relative movement can be a mechanical input of a microbend sensor for sensing a process variable, such as a flow rate in a vortex shedding flowmeter. The corrugations of each jaw (2ʺ, 3ʺ) comprise generally flat areas (2 b , 3 b ) lying in a common plane for each jaw (2ʺ, 3ʺ) and extending perpendicular to the displacement direction of the jaws (2ʺ, 3ʺ), and projections (2 c , 3 c ) extending in the displacement direction of the jaws (2ʺ, 3ʺ) and positioned between the flat areas (2 b , 3 b ). The projections (2 c , 3 c ) of each jaw (2ʺ, 3ʺ) oppose the flat areas (2 b , 3 b ) of the other jaw (2ʺ, 3ʺ) with the optical fibre (5) being held between the projections. Upon receiving an overload which tends to press the jaws together, the projections of one jaw press bends of the optical fibre (5) against the flat areas of the other jaw.
