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摘要： A tool for stabilizing slack fiber cable that has been withdrawn from a cable duct includes an inner sleeve portion for stabilizing the end portion of the cable remaining in the duct and a collar that is coupled to the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： 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 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.

摘要： The relative position of a cable (10) within a pipe (16) is obtained by first applying a locating signal to a metallic part (12) of the cable so that the locating signal radiates beyond the pipe. The strength of the locating signal is measured at two separate distances from the cable via a pair of signal detectors (24, 26). By comparing the difference in the locating signal strengths to a predicted differential locating signal strength for a given cable depth within a pipe of known parameters, the actual cable depth can be detected.

摘要： The exact position of a work location (24) is mapped by the aid of at least three differential Global Positioning Satellite (GPS) receivers (12, 14, and 16) situated proximate the work location. Each of the differential Global Positioning Satellite (GPS) receivers establishes its own exact position and transmits that information to a spatial positioning system receiver (18) at the work location that determines its position from the position of the individual differential Global Positioning Satellite (GPS) receivers.

摘要： Lightning strikes on or proximate to an optical fiber cable may be detected via a lightning detector (18) that monitors the characteristics of voltage present on a metallic sheath (12) associated with the cable. The lightning detector (18) detects excessive voltage levels, spikes and/or frequency variations associated with a lightning strike and generates an alarm signal communicated to a central monitoring facility.

摘要： A device (10) for marking the ground above a buried conveyance includes an upper and lower shells (12, 14) of a fracturable material joined at their edges to form a sealed body. A separator layer (16) devises the void between the two shells into an upper and lower regions (18, 20). The lower region contains a paint-adhesive mixture (22), whereas the upper region contains an indicia-bearing member (26) that identifies the entity responsible for the buried conveyance. To mark the buried conveyance, a technician deposits the marking device (10) on the ground and then steps on it, thereby fracturing the upper and lower shells to release the paint-adhesive mixture and the indicia-bearing member for adherence to the ground by the adhesive.
