摘要： Repair of a damaged portion of a cable sheath may be effected with the aid of a sheath repair kit comprised of an enclosure (10) and a volume of encapsulant (36). The enclosure (10) includes first and second members (12), both having an interior axially extending channel in communication with openings (20.sub.1 and 20.sub.2) in ends of the respective member to receive the damaged cable portion in the channel. The second member is shorter than the first member and has a cross-section smaller in area than that of the channel in the first member to enable receipt of the second member in the channel of the first member. In this way, the first and second members will capture the damaged portion of the cable, as well as a volume of the encapsulant (36) added to the channel of the first member to immerse the damaged cable portion.

摘要： A system for selectively grounding each of a plurality of short-haul buried utility conveyances coupled to a common long-haul buried utility conveyance to enable a conveyance locating signal transmitted through the long-haul conveyance to travel from the long-haul utility conveyance to a selected short-haul utility conveyance. The system includes a first optical switch for selecting each of the plurality of short-haul utility conveyances to be grounded, where the first optical switch is adapted to receive an optical signal and selectively output the optical signal on one of a plurality of optical fibers; and a second optical switch coupled to each of the plurality of optical fibers for grounding each short-haul utility conveyance in response to the optical signal on a corresponding optical fiber.
