摘要： A conductive splint for repairing a damaged metallic sheath of a fiber optic cable includes a C-shaped stabilization element that spans the damaged area and a conductive stabilization component that attaches to the C-shaped stabilization element and provides for electrical connection across the section of damaged sheath. The conductive stabilization component includes a pair of end clamps that have an inner barbed surface for penetrating into and contacting the metallic sheath, and a conductive brace that is coupled between the clamps, the combination of the clamps and brace forming an electrical path across the damaged section. A heat shrink blanket is used to encapsulate the combination of the C-shaped element and conductive stabilization component, preventing further corrosion in the damaged section.

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： The present invention is an apparatus and method for removing a portion of a cable sheath. First and second opposing blades are adjustable to a cutting depth using adjustment screws and continuity testers that signal contact between each blade and a metallic sub-sheath. The blades are inclined at an angle to a transverse plane of the cable, and are contoured to conform to the sheath radius. A guide including neoprene rollers keeps the cutting assembly aligned on the cable. The cutting assembly is drawn along the cable, removing the sheath.

摘要： An Aerial Inspection system is presented. The Aerial Inspection system includes an Aerial Inspection device. The Aerial Inspection device includes an upper section and a lower section. A passageway is formed within the Aerial Inspection device when the upper section and the lower section are connected. The passageway runs the length of the Aerial Inspection device. The passageway envelops a cable. Wheels connected to the upper section of the Aerial Inspection device protrude into the passageway and make contact with the cable. The Aerial Inspection device (e.g., the wheels) rests on the cable during operations. Cameras are positioned in the Aerial Inspection device to view the cable. As the wheels rotate, the Aerial Inspection device moves along the cable taking images of the cable. The cameras transmit images to a display for viewing or store the images for processing. As a result, faults in the cable may be detected and viewed from the ground or a remote location.

摘要： The location of a casing (10) as it is pushed through the earth during installation is monitored by transmitting a locating signal into a water reservoir (24) that supplies water into an auxiliary water pipe (18) that runs substantially the length of the casing for the purpose of monitoring the level of the casing. The water carries the signal into the pipe so that the signal radiates above the ground along the length of the casing. By detecting the signal via a cable locator (30), the location of the casing can be monitored during installation.

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： 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.

摘要： The present invention relates to a method for interpreting data obtained by measuring a length of optical fiber using an optical time domain reflectometer (OTDR), and comparing that measurement to a reference measurement. The technique uses statistical inference to determine a whether a reference trace is valid by comparing that trace to a more recent test trace. One technique uses a chi-squared best fit of an array reflectance spike occurrences along the fiber to a historical reference array.

摘要： The present invention relates to method for interpreting data obtained by measuring a length of optical fiber using an optical time domain reflectometer (OTDR), and comparing that measurement to a reference measurement. The technique uses statistical inference to determine a likely cause for a length measurement to be shorter than a reference length. One technique uses a chi-squared best fit of an array reflectance spike occurrences along the fiber to a historical reference array. In that way, it can be determined whether the missing portion of the tested fiber is at an end or between the ends, providing evidence that the short length measurement results from a fiber break or from the intentional removal of a reserve loop.
