  • Patent number: 7961999
    Abstract: There is disclosed an optical waveguide distribution device having a distribution panel with splice cassettes removably connected thereto. Fiber optic splices are placed within the splice cassettes, so that removal of the splice cassettes allows improved access to the splices. In addition, the distribution panel includes a front wall upon which are positioned a plurality of couplings. The front wall is removably connected to the distribution panel to allow improved access to the couplings.

  • Patent number: 7298950
    Abstract: The invention relates to a distribution cabinet (10) for optical fibers, comprising a housing (11) and a frame (18) that is pivotally mounted inside the housing (11). Cables encompassing optical fibers that are guided therein can be routed into and/or directed out of the distribution cabinet, the cables being routed to the frame (18) from a rear side (14) of the housing (11) and being routed away from the frame in the direction of the rear side. Subassemblies are fastened to the frame (18) in order to connect the optical fibers that are guided within the cables. At least one holding device (23) for the cables is fastened to the pivotally mounted frame (18), the cables being fixable to the holding device (23). The holding device (23) is configured so as to be pivotable relative to the housing (11) along with the frame (18), while also being pivotable relative to the frame (18).

  • Patent number: 7027704
    Abstract: An optical distribution device has first connector points for the connection of incoming light waveguide cables, second connector points for the connection of outgoing light waveguide cables and at least one light waveguide connector cable having at least one connecting device on one or both ends for connecting at least one of the first connector points to at least one of the second connector points. Each connection device is provided with an electrical code memory device for storing an identification code and each of the first and second connector points are provided with an electrical code reader device connected to the associated code memory device for reading the identification code when the associated connector device is connected to one of the connector points. A controller is connected to the code reader device for evaluating the identification code to identify the optical connection effected by the light waveguide connector cable.

  • Patent number: 6650811
    Abstract: The invention relates to a protection for glass fibers for telecommunication with air-space paper-insulated core (H1 to Hn) in distribution fields arranged in the form of cassettes. Several air-space paper-insulated cores (H1 to Hn) are assembled according to their length in a composite element (VE1 to VE5), wherein the ends can be cut to the required length if necessary. The air-space paper-insulated acres (H1 to Hn) are assembled according to their length in a discontinued manner using connecting shaped parts or in a continuous manner along the generatrix of the air-space paper-insulated cores.

  • Patent number: 6052504
    Abstract: The invention is concerned with a hood sleeve which is formed from a sealing body and a hood body these two parts being held together with the aid of a mechanical retaining device, initially without a sealing effect. The sealing-off between the hood body and the sealing body is carried out with the aid of a seal system which is activated by a functional element, for example in the form of an eccentric.
