Abstract: A method of laying an at least partially buried fiber optic cable includes placing a fiber optic cable with at least one associated alternating electromagnetic field emitting locating transponder (AEFELT) underground such that at least one AEFELT is buried underground.

Abstract: A self-supporting fiber optic cable includes a messenger section having at least one strength and anti-buckling member enclosed within a jacket and a carrier section enclosed within a jacket that is joined to the jacket of the messenger section by a web. In a preferred embodiment of the present invention, carrier section does not include strength members and the optical fibers are set with a high EFL. The greater EFL accommodates elongation of carrier section without transmission of stress to optical fibers. In addition, the preferably generally cylindrical internal surface of a tube or jacket curves the optical fibers creating EFL, for example, the fibers are guided by the internal surface in a helical path. Resistance to carrier section elongation and contraction can be controlled by varying the length of the web connecting the carrier and messenger sections.

Abstract: A hybrid cable with optical fibers and metallic conductors has a cable jacket with a first slot (14) for reception of optical fibers (121, 122) as well as a second slot (24) for reception of the electrical conductors (221, 222). The parts (1, 2) of the cable jacket forming the slots are connected to one another with a crosspiece. The cable has a preferred bending line, which is formed by the symmetrical axis (4) of the cable. The cable is especially suited for optical signal transmission in combination with the transmission of electrical data signal or supply voltage.

Abstract: A method for connectorizing fiber optic cables includes arranging a plurality of connectorized optical fiber jumpers having first and second opposed ends, such that the first end of each jumper is in parallel alignment with respect to the first end of each other jumper. Each of the second ends of the jumpers have a fiber optic connector disposed thereon. The first ends of the jumpers are then spliced onto a corresponding plurality of first ends of optical fibers of a fiber optic cable. Each of the first ends of the optical fibers of the fiber optic cable are also arranged in parallel alignment with respect to each other optical fiber so that the first ends of the optical fiber jumpers are axially aligned in an end-to-end relationship with the corresponding first ends of the optical fibers of the fiber optic cable. A jumper insert which has a tapered channel and a jumper seat which has a plurality of lengthwise extending bores which are provided to assist in arranging the jumpers in parallel alignment.

Abstract: A multi-link boot assembly has a number of separate links which can be connected to form a flexible boot assembly capable of maintaining a predetermined bend radius as off-axial loads are applied, thereby effectively dispersing stresses along a cable as the cable is flexed or bent. Each link of the multi-link boot assembly includes a body portion defining a lengthwise extending bore for receiving the cable. The body portion extends between first and second opposed ends and generally includes a female section at the first end and a male section at the second end. The female section defines an opening for receiving the male section of another link during the assembly of the multi-link boot assembly. In order to connect each link with another link to form the flexible boot assembly, each link includes a connecting element at each of the first and second opposed ends which cooperably engages a corresponding connecting element of an adjacent link.

Abstract: The receptacle permits selected ones of the ferrules to be withdrawn from the receptacle without disconnecting the fiber optic connector from the receptacle and without disassembling the receptacle. As such, the ferrule that is withdrawn from the receptacle can be disconnected from the corresponding ferrule of the fiber optic connector assembly without disconnecting the other ferrules from the corresponding ferrules of the fiber optic connector assembly.

Abstract: The pulling grip includes an elongated, flexible pulling grip housing for use in installing fiber optic cable and, more particularly, for installing a fiber optic cable which contains a number of pre-connectorized optical fibers. The pulling grip housing includes first and second portions which mate to form the pulling grip housing and which open to provide access to an internal cavity for placement of the pre-connectorized optical fibers of the fiber optic cable. The pulling grip housing can secure the connectors within the internal cavity to prevent undesirable tangling of the optical fibers during installation. For example, the pulling grip housing can include an adhesive surface or a number of slots for retaining respective ones of the connectors.

Abstract: A universal tool for cutting fiber optic cables and, more particularly, for cutting buffer tubes of various diameters and wall thicknesses includes first and second housings having respective inner surfaces. The inner surface of each housing can define a respective groove which, in turn, defines a respective longitudinal axis. The second housing is adjustably attached to the first housing so that the first and second grooves are maintained in an aligned relationship to thereby form a channel having a width which can be controllably adjusted so as to substantially match the diameter of the buffer tube to be cut, thereby allowing the universal tool to access the optical fibers within buffer tubes of different diameters. The tool also includes a first blade which is at least partially disposed in the first housing so that the first blade extends a predetermined distance into the respective groove.

Abstract: Disclosed is a fiber organizing tool having a frame with a channel with narrow raised sidewalls for piercing an adhesive tape to be laid on fibers laid straight in the channel. The optical fibers are arranged in a narrow slot in a member hingedly mounted to the frame.
