An electrical connector assembly for terminating first and second electrical wires, the electrical connector assembly comprising a housing including a compartment for receiving first and second IDC elements and a cap movably mounted to the housing to cover the compartment. The cap is movable between an open position and a closed position. The cap includes a general body portion, a wire retention portion, and a latching mechanism. The wire retention portion includes first and second wire holders to retain and align the respective electrical wires within the housing for engagement with a gripping portion of the respective IDC element when the cap is placed in a closed position. The gripping force of the wire holders is less than a gripping force of the IDC elements. The latching mechanism can releasably fasten the cap to the housing when the cap is placed in a closed position. When the cap is returned to an open position after the cap was placed in the closed position, the first and second wires are retained by the first and second IDC elements and the first and second wire holders disengage the first and second wires from the cap.
摘要:
A device for preparing an optical fiber for interconnection includes means for grasping the optical fiber at a first location along the optical fiber, means for scribing and breaking the optical fiber a first select distance from the first location, the means for scribing and breaking including guides for supporting and sliding the means for grasping along the guides in fixed relationship to the means for scribing and breaking, and means for polishing the optical fiber as broken, the means for polishing being connected to the means for breaking. The device also includes a polishing surface fixedly connected to the means for grasping. The polishing surface supports the means for grasping at a second select distance from the first location, the second select distance being shorter than the first select distance. The optical fiber is linearly moveable with respect to the polishing surface.
摘要:
A duct for distributing one or more optical fiber communication lines. The duct comprises an elongated main body having a length and a conduit portion with a lengthwise bore formed therein. The conduit portion contains one or more optical fiber communications lines. The duct also includes a flange portion extending lengthwise adjacent the main body to mount the duct to a generally flat surface, wherein the duct further includes an additional fiber channel for distributing at least one additional optical fiber at least a portion of the length of the duct. The duct can also be formed as a two piece duct system. The duct can be utilized in a drop access location system for horizontal cabling in multi-dwelling unit (MDU) applications.

A system for installing communications in a hallway of a building comprises a duct having a conduit portion with a bore formed throughout and containing one or more communications lines and a mounting portion to mount the duct to a generally flat surface, the mounting portion including an adhesive disposed thereon, and a duct applicator tool to continuously receive the duct from a storage structure. The applicator tool includes a generally planar frame that supports at least one duct channel that receives the duct and provides a support surface that places a pressing force onto the duct as the duct is applied to the generally flat surface. The applicator tool includes one or more duct guides disposable on at least an end of the frame, where the one or more duct guides guide the duct from its storage structure to the at least one duct channel.
摘要:
A drop access location system and method, where the system includes a duct containing one or more communications lines, where the duct is mountable to a generally flat surface. The system also includes a drop access box including a base and a removable cover having a low impact profile and or decorative appearance. A mounting section of the base is configured to fit over an outer shape of the duct and overhang therefrom. Slack storage is provided and includes one or more guides to route an accessed communications line to a coupling and to store excess amounts of the accessed communications line. The coupling device mounting area is configured to receive a coupling, adapter, or splice that connects the accessed communications line to a drop cable. The drop access location system and method can be utilized for horizontal cabling in multi-dwelling unit (MDU), multi-tenant unit (MTU) and other building applications. A system for installing the drop access location system is also provided.
摘要:
An optical connector for terminating an optical fiber comprises a housing configured to mate with a receptacle and a collar body disposed in the housing. The collar body includes a ferrule securely disposed in an opening of the collar body, the ferrule including a central bore that defines an axis, and a housing portion disposed in a generally central portion of the collar body. The housing portion includes an opening to receive a gripping device to grip an optical fiber. The ferrule is axially moveable independent of the axial movement of the optical fiber and gripping device. The optical connector can be thermally balanced over a temperature range of at least 100° C.

摘要:
An optical fiber connector comprises an outer housing configured to mate with a receptacle and a collar body disposed in the outer housing. The collar body receives and secures a ferrule in a first portion of the collar body. The ferrule includes a central bore that defines an axis. The ferrule further includes a fiber stub disposed in a portion of the central bore, the fiber stub comprising a first optical fiber having a first end proximate to an end face of the ferrule and a prepared second end terminating within the ferrule. The collar body further includes a second portion that includes a housing portion to house a gripping device that grips a second optical fiber.
摘要:
A fiber optic connection system having a housing which receives a plurality of novel splice trays which are adaptable for use in either interconnection or cross-connection of the fibers. Each splice tray is formed of an upper tray section (having a reel for storing excess fiber slack in the first group of fibers and a splice area with clips for retaining splice elements) and a lower tray section which is either an interconnect card or a cross-connect card. The interconnect card has another reel for storing excess fiber slack in the second group of fibers, while the cross-connect card has no such reel but rather has walls for guiding the group of second fibers to a common exit point on the cross-connect card. The lower tray section is removably attached to the upper tray section whereby an existing splice tray can be modified from an interconnection configuration to a cross-connection configuration and vice-versa. The housing includes a pair of rails having holes therein for receiving pins on the edge of each splice tray whereby the trays may be pivotally attached to the rails in a page-type array. A stabilizer bar having several tabs is attached to the lower rail to releasably secure the splice trays in one of three predetermined positions.
