摘要： An optical fiber transmission network for transmitting voice, data, or video signals between telecommunication units includes optical couplers which bend an optical fiber at a location in close proximity to the fiber end so as to allow coupling with the fiber through its side rather than through the end of the fiber. This eliminates the need for cleaving and polishing the fiber end, and results in a craft friendly way of terminating an optical fiber end with a telecommunication unit.

摘要： An optical bypass switch includes a normal state and a bypass state, a transmission optical fiber having a signal withdrawn therefrom and injected thereto in its normal state so as to be capable of use in a ring or bus architecture. In the bypass state of the switch, the transmission optical fiber is substantially disengaged so that a signal being transmitted thereby can bypass the switch, and in this state optical fibers connected to a transmitter and a receiver of the bypass switch are maintained in a bent attitude so as to allow signals to be withdrawn and injected thereinto. A loop back path, e.g. a connector optical fiber, is provided which allows a path between the transmitter and the receiver to be completed in the bypass state of the bypass switch, and logic circuitry is provided for analyzing signals detected by the receiver which should have originated from the transmitter for evaluating a state of operation of the transmitter, receiver, and connecting means therefor. Whenever the logic circuitry detects a malfunction in any of these elements, e.g. the transmitter, the receiver and connecting structure therefor, the optical bypass switch is kept in its bypass state and prevented from re-engaging the transmission fiber so as to prevent the bypass switch from optically coupling to the transmission fiber when its electro-optic elements are not functioning properly.

摘要： A tap for coupling light (3) from an intermediate portion (2) of an optical fibre core and a light element (6, 8) by passing light (3) through a side of the optical fiber (1) includes an optical coupler in contact with an outside surface of an optical fiber (1) which is bent and disposed in a plane. A light reflector (4, 14) extending transverse to the plane deflects the withdrawn light (3) towards the end surface (5) of a light element (6, 8) disposed completely outside the plane. The tap may be used as a read tap to withdraw light (3), or as a write tap to inject light (3) in optical fiber networks. A spring biased closure member (20) urges the optical fiber (1) to be maintained in bent registration with the optical coupler within the plane. A rail (19) and channel (18) is used to conveniently guide a tap closure member (20) against the optical fiber (1). Simple tools and general craft training and knowledge may be applied to insert into and remove the optical fiber (1) from the tap.

摘要： 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.

摘要： An optical fiber waveguide tap (34) handling tray (28) is provided for use with a cable (30) containing a plurality of optical fiber waveguides (46) which are separated from the cable (30) and exposed in a section thereof. The tap handling tray (28) comprises a frame, a clamp (33) for clamping the cable (30) to the frame adjacent the section thereof so that the exposed optical fiber waveguides (46) are thereupon physically secured to and contained within the frame, at least one optical tap (34) secured to the frame for engaging and bending at least one of the plurality of optical fiber waveguides (46) against an optical coupling medium having an index of refraction selected to match the index of refraction of the optical fiber (46) so that light energy may pass through a side of the optical fiber (46) and through the optical coupling medium, and wherein the optical tap (34) defines an obtuse guiding angle (52) arranged to lie in a path with which the fiber may freely be aligned within the frame after the cable has been clamped thereto. Taps (34) having differing obtuse guiding angles (52) may be selectively installed by the craftsman within the tray in order to select a desired amount of light energy interchange at the tap field location.
