  • Patent number: 8452172
    Abstract: The present invention relates to testing a passive optical network having a head end and a plurality of terminals, which terminals are connected to the network at a respective plug and socket arrangement located at customer premises. A test device is provided having a standard plug for connection in place of a terminal in the socket of the relevant customer premises. An identification device is provided in the socket. The test device is arranged to (i) read the identity of the identification device and (ii) test the line and transmit a result to the head end together with the identity so that the line to the customer premises can be tested remotely. When the line has been tested, the test device can be removed. Because the test device uses an existing connection, the optical (insertion) loss is reduced.

  • Patent number: 7866022
    Abstract: Cable is installed into a duct, by increasing cross-sectional areas of subducting provided in the duct, so as to allow the cable to be received into the subducting, and then decreasing the cross-sectional area of the subducting containing the cable so as to reduce the volume occupied by the subducting in the duct. Cables may be inserted into the subducting, for example, by forcing compressed gas through the subducting, which simultaneously inflates the subducting.

  • Patent number: 7842340
    Abstract: A fiber unit coating apparatus includes a chamber into which an uncured resin coated fiber unit is passed. Microspheres mixed with air are fed into the chamber via ducts and apertures. As a result rapid and even application of the microspheres can be achieved, and the system allows controllable application of the microspheres by varying the rate of flow of the air/microsphere mixture. Positive pressure chambers are provided to prevent the microspheres from blocking the inlet and outlet points where the fiber unit enters and leaves the chamber.
