A safety retention clip for installation in a module that stores a length of a communication line. The clip has a body formed of metallic sheet material. The body has a base portion, and a retaining finger portion joined to the base portion. A distal end of the finger portion is configured to overlie a communication line stored inside the module, and to retain the line close to a building wall on which the module is mounted if the module melts during a building fire. A mounting hole is formed in the base portion of the clip body, near a proximal end of the finger portion for insertion of a mounting screw. The hole extends through a boss that projects downward from the base portion, and the boss is sized to nest in a corresponding mounting opening in a base of the module in which the clip is installed.

A tool device for installing an optical fiber inside a user premises includes a neck, a coupling joined to the neck for attachment to a leading end of an adhesive syringe or an extension pole, and a head joined to a leading portion of the neck. The head has a leading edge of a certain width, and a passageway for receiving an optical fiber and guiding the fiber to a position proximate to the leading edge. The width of the leading edge is such that when the edge is held transversely across a structural corner containing an adhesive bead, and an optical fiber is received in the passageway in the head and directed ahead of the leading edge, the edge embeds the fiber in the bead when the edge is swept along the corner with the optical fiber positioned between the edge and the adhesive bead.

Tool device for installing optical fibers at user premises

An optical fiber distribution module includes a base having a surrounding wall, a cover, and a sealing element in the cover. A pair of cable ports are formed in the base wall to pass an outdoor fiber distribution cable through an interior region of the module. One or more fiber ports in the wall pass corresponding drop fibers from the interior region where the fibers connect to designated fibers of the distribution cable, to a number of premises for which the fibers are designated inside a multi-dwelling unit building. Grommet seals are dimensioned and formed to be inserted in any unused fiber ports, and to surround the distribution cable and the drop fibers in their corresponding ports. The grommet seals cooperate with the sealing element in the cover to seal all the ports from the environment when the module is closed.

A system forms, at an end of a multifiber ribbon cable, a multifiber ribbon cable segment having an enlarged core-to-core spacing. A UV-transparent mold is mounted on top of a chassis. The mold defines a plurality of individual fiber channels corresponding to individual fibers of the existing multifiber ribbon cable and having a spacing equal to that of the enlarged core-to-core spacing. Each individual fiber channel passes through the internal cavity. The assembled mold further includes an injection system for receiving light curable, flowable material from the reservoir and pumping system and feeding it into the internal cavity, and at least one vent for allowing air to escape from the internal cavity as the light-curable, flowable material is fed into the internal cavity. The injected material is cured by exposure to a curing light.

A fiber storage module having a removable supply spool is mounted inside a user premises. The module is arranged to retain the spool at either a first position where the spool can freely rotate, or a second position where the spool is locked. While the spool is removed from the module, a length of fiber sufficient to route from an entry point to the premises to the mounted module, and from the module to an optical device inside the premises, is wound on the spool. The spool with the wound fiber is retained at the first position inside the module, and the fiber is unwound and adhered or fastened to a supporting surface along a determined routing path at the premises. The spool is then locked at the second position, and a length of the remaining fiber is removed for connection to the optical device.

Method of installing an optical fiber at user premises

A ribbon transition tool modifies a 200 &#x3bc;m ribbon for splicing to a 250 &#x3bc;m ribbon. A spreader comb is fixedly mounted at the front end of the base of the tool. A straight comb is slidably mounted to the base behind the spreader comb. The combs each have a plurality of fiber channels corresponding to the fibers in the fiber ribbon. At the front end of the spreader comb, the channels have a spacing matching the initial spacing of the fiber ribbon. At the rear end of the spreader comb and throughout the straight comb, the channels have a spacing matching the modified spacing. An anvil is mounted into the base so as to be movable between a lowered position, in which the anvil lies underneath the straight comb, and a raised position, in which the anvil fills the gap between the combs when they are separated.

A device for retaining an optical fiber or cord at a desired position while the cord is being installed along a defined route at a user premises. The device includes a bend limiter having an open channel that extends between opposite ends of the limiter, wherein the channel is sized to receive a cord and allow the cord to slide freely inside the channel. An elongated retainer is arranged to overlie the bend limiter and thus close the channel when the retainer is secured to the bend limiter, so that the cord is confined inside the channel as the cord slides between the opposite ends of the bend limiter. A latch is arranged to close the device by securing the retainer to the bend limiter, and the bend limiter is configured to conform in shape with one or more surfaces against which it will be installed at the premises.

Optical cord retaining device

A compact adapter module for installation at customer premises includes a base for mounting on a supporting surface, and a cover. The base is constructed for mounting a connector adapter operative to connect two communication lines to one another at a given location along a routing path at customer premises. A cover protectively encloses the adapter and connectors mated to the adapter which terminate the lines. Space inside the covered module is limited substantially for storing only the adapter and mated connectors, so the module is compact in size and unobtrusive when mounted at the given location. The lines are received at two ports of the module, and an edge of the base is flush with the supporting surface at each port so the lines can be adhered directly to the supporting surface at the ports. Any adverse visual impact of the lines at the module is therefore minimized.

A method for splicing a first optical fiber ribbon cable to a second optical fiber ribbon cable includes separating an end of the first optical fiber ribbon cable into loose optical fibers, and re-ribbonizing the loose optical fibers into a ribbonized end having a second pitch different from the first pitch of the original first optical fiber ribbon cable. The method further includes inserting the ribbonized end into a mass fusion splicer having the second pitch, and splicing the ribbonized end to the end of the second optical fiber ribbon cable using the mass fusion splicer.

A module for storing optical fiber at user premises. A fiber supply spool has at least one winding section for storing a length of fiber to be routed at the premises. A spool plate has a base with retaining fingers for mounting the supply spool for rotation, and a hinge pin supported between the ends of two arms extending from the base. An elongated adapter plate is arranged for fastening over an opening cut in a drywall at the premises. The adapter plate includes at least one hinge mount for seating the hinge pin on the spool plate for swiveling movement. The spool plate can swivel on the adapter plate together with the mounted spool between a position where fiber is unwound from the spool for routing at the premises, and a position where the spool with remaining fiber is passed through the opening to be stored behind the drywall.

Behind-the-wall fiber spool module

An optical fiber storage module has a base, and a wall having an opening for paying out an optical fiber from inside the module. Spool retention fingers extend from the base. One or more fingers have a first rim at a first height above the base, and one or more fingers have a second rim at a second height above the base. A fiber supply spool has a hub, and an annular support disk inside the hub which forms a third rim. The spool is movable on the retention fingers between a first position where the third rim of the support disk is captured between the first and the second rims on the retention fingers, thus allowing the spool to turn when fiber is unwound, and (b) a second position where the spool engages one or more bosses formed on the module base to lock the spool from further rotation.

Fiber optic storage module installation at user premises

A module for optical fiber installation and storage at customer premises has a base, and a fiber supply spool mounted for rotation on the base. An elongated adapter plate has a front end portion for mounting a connector adapter. A rear end portion of the adapter plate has first hinge parts at one side of the plate, and the fiber supply spool has second hinge parts for engaging the first hinge parts of the plate to define a hinge axis. The adapter plate can swivel about the hinge axis between a position where the plate lies flush on the supply spool and the spool can turn as fiber unwinds, and a position where a port of a connector adapter mounted on the plate is accessible for connection to an outside device when the module is closed, and the plate engages the module base to restrain the spool from rotation.

Module for optical fiber installation and storage at customer premises

A module for installing and storing an optical fiber includes a supply spool containing fiber for routing between the module and a service module at a customer premises. An adapter inside the module connects the fiber on the spool with an outside connector associated with a device at the premises. A wall of the module has a payout opening, and an edge of the module base is set back from the outside surface of the wall at the payout opening. A ramp area formed on the base inclines downward from the spool toward the payout opening. A lower edge of the ramp area substantially coincides with the setback edge and is substantially flush with a supporting surface beneath the base. Fiber drawn from the module can be adhered to the supporting surface at the payout opening and thus ameliorate any adverse visual impact of the fiber near the module.

A tool system for threading an optical fiber through a hole formed in a wall at customer premises, and for protecting the fiber inside the wall. A tool body has forwardly projecting fingers for capturing a connector at an end of the fiber from a direction approaching a front face of the connector. A back end of the tool body is arranged to engage a rod handle of such length that its free end can be threaded through the hole and out the opposite side of the wall. Using the handle, the tool body is pulled through the hole along with a captured connector and associated fiber. A hole plug has a hollow cylindrical body and an access slit for passing the fiber inside the body for protection. The plug body has teeth for engaging the premises wall and retaining the plug at a desired angular position in the wall.
