    • A device for monitoring light traveling in an optical fiber having a body, a passage in the body adapted to receive an optical fiber, a discontinuity in a portion of an optical fiber received in the passage through which light can exit the fiber, and an optical detector unit adapted to provide a signal representative of light exiting the received fiber through the discontinuity. The device can include provision for monitoring a selectable one of a plurality of fibers, and may be constructed either as a standalone unit for attachment to a multiple fiber signal connector device such as an optical crossbar switch, or as an integral part of a switch or other optical device. The discontinuity may be formed as a permanent part of a fiber through which the signal to be monitored passes, or may be formed temporarily when a signal in a fiber is to be monitored.

    • A right angle bend mount (100) for bending an optical fiber into the plane of a circuit board (200). The mount (100) includes a base and a cover that is pivotably connected to the base by a hinge. A clamp is formed by a first pair of opposed surfaces of the base and cover adjacent the hinge. This clamp fixedly grips a ferrule portion of the optical fiber when the base and the cover are closed together. A second pair of opposed surfaces of the base and cover forms another clamp. This clamp fixedly grips a non-ferrule portion of the optical fiber when the base and the cover are closed together. A bent portion of the optical fiber between the ferrule portion and the gripped non-ferrule portion is disposed in a non-gripping gap (120) between the base and the cover when the base and the cover are closed together.

    • An instrument for detecting optical signals in optical fibers of various diameters includes a piston adapted to urge a portion of an optical fiber against a light detector, the piston being movable between open and closed positions, and having at least two piston surfaces, one defining a first precision bend geometry adapted to urge a fiber of a first diameter against the detector, and another defining a second precision bend geometry adapted to urge a fiber of a second diameter against the detector. The piston is biased toward the detector by a spring mechanism which also applies a predetermined amount of pressure against the fiber. The piston includes a mandrel having the two piston surfaces, the mandrel further having a shaft such that it may be rotated about the shaft to present either one of the piston surfaces to the detector. Indicia may be provided on the mandrel shaft, or the body, to visually indicate which piston surfaces has been selected. The mandrel may be moved between the first and second orientations without disassembling the device, although such movement is allowed only when the piston is in a retracted position away from the detector. The mandrel includes detent means for releasably securing the mandrel in either one of the first and second orientations. A novel ambient light shield is also disclosed.

    • A tap for withdrawing light from an intermediate portion of an optical fiber core by passing light through a side of the optical fiber comprises an optical coupler in contact with an outside surface of an optical fiber which is bent and disposed in a plane. A light reflector extending transverse to the plane deflects the withdrawn light towards the end surface of a light element disposed completely outside the plane. A similar arrangement may be used to inject light to an intermediate portion of an optical fiber. The tap may be used as a read tap to withdraw light or as a write tap to inject light in optical fiber networks. A spring biased closure member urges the optical fiber to be maintained in bent registration with the optical coupler within the plane. Simple tools and general craft training and knowledge may be applied to insert into, and remove the optical fiber from, the tap.
