摘要： The present invention is an apparatus and method for coupling optical fibers having disparate connectors. First and second indexing bodies are moved relative to each other to bring into alignment selected receptors for accepting the disparate connectors. Receptors for several different connectors are available on at least one of the indexing bodies. The indexing bodies may be disk-shaped and attached for rotation about a common axis, with the receptors being arranged circumferentially. The apparatus may also includes a spring clip and magnet for mounting and storing on fiber optic bays and cabinets.

摘要： A metal tube slitter is presented. A housing includes a drive shaft for moving cable through the housing and a blade truck. The blade truck houses a blade used for penetrating the cable. A shoulder screw adjusts the blade truck and as a result adjusts the penetration of the blade into the cable. The drive shaft is attached to a drive knob. As the drive knob is rotated the drive shaft also rotates and moves the cable through the metal tube slitter. After the blade penetrates the cable, the blade cuts the cable as the cable is moved through the metal tube slitter by the drive shaft.

摘要： An apparatus for locating a buried utility conveyance, such as an undersea cable, beneath a body of water. The apparatus generally comprises a submersible housing that contains a variable ballast system for selectively controlling the buoyancy of the apparatus, and a detector assembly for locating the conveyance. The detector assembly includes first and second signal generators and first and second signal detectors vectoring the location of the conveyance. An operator guides the detector relative to a target search location through cables attached to the housing and the variable ballast system. A camera generates images of the target search location for use by the operator to control the apparatus through an umbilical cable connected to the housing.

摘要： A radio tower light system utilizes a ground-level semiconductor optical light source and includes fiber optic cabling that is strung along the tower to the various desired locations for the beacon light. A lens system, at each beacon site, is coupled to the termination of a fiber optic cable and used to magnify and radiate the optical signal in the desired direction. The use of a ground-based light source eliminates the need for a technician to climb the tower (or lower the beacon) upon failure of the light source.

摘要： A bracket for supporting spare fiber optic cable includes a pair of parallel, spaced-apart cross arms supported by a center post, where the center post may then be attached to the floor of a manhole, or other location used to store spare fiber cable. The spare cable is then wound around the cross arms and available for later use. The hanging bracket is located in the manhole such that the cross arms face the cable conduits in the sidewalls of the manhole, allowing the fiber to be easily pulled through the conduit as it unwinds from the bracket, eliminating the problem of kinks in the cable as it is pulled.

摘要： The present invention is directed to a method and apparatus for testing a fiber-optic cable. An Optical Time Domain Reflectometer (OTDR) is presented. Test signals are generated from the OTDR and received by the OTDR for processing. The received test signals are sampled and analyzed. The received test signals include reflectance spikes and a slope. A first-order derivative is taken of the received signal. The first-order derivative is then filtered to remove the reflectance spikes and the slope. Discontinuities in the filtered first-order derivative denote a fault in the fiber-optic cable.

摘要： A system (10) for monitoring a cable (14) for fault in the metallic sheath (12) includes a transmitter (16) for applying a signal to a first end of the metallic member at periodic intervals. A receiver (18) periodically measures what if any signal exists at a second end of the metallic member in synchronism with the application of the signal so that each measurement is made not long longer than the interval during which the signal is applied to the metallic member. The receiver communicates the measurements to a central facility for evaluation to determine whether the metallic member exhibits a fault.

摘要： An arrangement for monitoring the integrity of the spare fibers within a fiber optic cable includes a transmitter unit at a first location and a receiver unit at a second location (which may be upwards of 50 miles from the first location). A test signal is launched by a laser source in the transmitter unit along each spare fiber, and a set of threshold detectors is used at the receiver unit to monitor the received signal level. If the level of a received test signal along a spare fiber drops below a predetermined level (or if the fiber fails completely), an alarm signal is generated to alert a technician regarding the need to repair or replace the failed spare fiber. The alarm signal may be a “local” alarm signal generated at the second/receiver location or may be communicated back to the first/transmitter location as a “remote” alarm signal.

摘要： A utility conveyance (10), such as a pipe, cable or duct, designed for burial in surrounding earth (12) carries a passive warning mechanism (16), preferably a water-soluble dye embedded in the conveyance. The dye, when exposed to moisture (e.g., rainwater in the surround earth) will bleed from the conveyance and discolor the surrounding soil, thus alerting any contractor attempting to excavate in the surrounding area.

摘要： Location of an underground utility conveyance having a metallic part (10) running along its length is enhanced by providing a plurality of selective conduction units (30) spaced along the length of the conveyance. Each selective conduction unit selectively shunts the metallic part of the conveyance to ground at a point between its first and second ends in response to a particular pattern of pulses modulated onto the locating tone impressed on the metallic part by a cable-locating signal generator (14) to cause only that portion of the metallic part lying between the first end and said point to radiate the locating signal. In this way, the amplitude of the locating signal radiated above the earth for locating purposes is increased.
