摘要： A tool for stabilizing slack fiber cable that has been withdrawn from a cable duct includes an inner sleeve portion for stabilizing the end portion of the cable remaining in the duct and a collar that is coupled to the sleeve and attaches to the exterior periphery of the duct. A set of cable-locking rollers is coupled to the collar and used to engage the slack portion of the cable and hold it in place as various fibers within the cable are repaired.

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 One technique uses a chi-squared best fit of an array reflectance spike occurrences along the fiber to a historical reference array.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 One technique uses a chi-squared best fit of an array reflectance spike occurrences along the fiber to a historical reference array.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.

摘要： Filter/protection units positioned along a fiber optic cable are tested. The fiber optic cable includes a metallic sheath surrounding the cable. A cable locating unit generates an electric signal. The metallic sheath conducts the electrical signal. The electric signal creates a voltage within the metallic sheath. The voltage level is below a specified flashover point or threshold of a normally operating filter/protector unit. As a result, any filter/protector units that are triggered by the electric signal are considered faulty.

摘要： To locate a buried conveyance (10), electromagnetic signaling information is collected at spaced intervals along the conveyance with the aid of a locating device (14). A processor (21) receives such information from the locating device (14) and then geographically orders the information in accordance with the geographic coordinates of the location at which it was obtained. Once geographically ordered, the information is then provided on a display (22) to provide a visual representation of the information as a function of the conveyance length.

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 crimper tool for use in attaching lugs to the metallic sheath covering on fiber optic cables includes a pair of blocks, with a trough formed in each block to accommodate the cable when one block is placed on top of the other. Each block includes at least one slot for positioning a proper-sized die to perform the crimping action. The use of this block crimper tool is particularly advantageous when a hand-held crimper is too small to accommodate a large diameter fiber cable.

摘要： A bond device for fiber optic cables allows for an electrical bond to be made between the cables without the need to first strip away the outer poly covering on each cable. The bond device comprises a metallic lug element which includes a cable-receiving channel, the interior surface of the channel having at least one (and, preferably, a plurality of) outwardly extending barbed tooth. As the metallic lug is clamped around the cable, the tooth/teeth penetrate the outer poly layer and contact the underlying metallic sheath material. The lug may then be coupled to another such lug via a stranded wire bonding ribbon attached between the lugs.

摘要： A color-coded restoration splice block is formed to match the coloring of the individual fibers within a standard ribbon cable. Thus, during the splicing operation, the proper pairs of fibers will be mated and laid within the same fiber-holding groove, eliminating the problem of “crossing” fibers from one ribbon to another as they are spliced together. In a preferred embodiment, the entire groove is colored to match the sheath color of the pair of fibers disposed in the groove.
