  • Patent number: 6803524
    Abstract: A housing has second and third bays, where each bay receives equipment therein. The housing also has a plurality of lines traveling therein from a site such as a first bay to the second bay and the third bay. A line routing device is positioned above the second and third bays and routes the lines from the site to the second and third bays. Each line is secured at a common securing point above the second and third bays, and each of the second and third bays has a vertical down-channel at one side thereof. Each line extends from the securing point, through the line routing device, and down one of the down-channels such that the line when positioned to hang in either down-channel hangs substantially the same length within such down-channel.

  • Publication number: 20040165889
    Abstract: A telecommunications system includes a passive optical network (PON) including an optical splitter configured to serve optical network terminations (ONTs) at respective ones of a plurality of subscriber premises. The system further includes an optical network unit (ONU) coupled to the PON and configured to provide communications for the plurality of the subscriber premises. The optical splitter may directly subtend the ONU, and the optical splitter and the ONU may be co-located, for example, at the same pole or pedestal. The ONU may be powered by a power source located at a remote terminal (RT). A composite fiber/conductor cable may couple an optical line terminal (OLT), which may be positioned at a central office (CO) or the RT, and the power source to the optical splitter and the ONU, respectively.

  • Patent number: 6215930
    Abstract: A fiber optic cable having a plurality of buffer tubes. Within at least one of the buffer tubes is a plurality of main fibers. Within the cable outer sheath, the main fibers are factory-spliced with optical splitters at predetermined distances. Distribution fibers are factory-spliced to the outputs of the optical splitters. The distribution fibers reside within distribution buffer tubes, and are available for access at substantially any location along the length of the fiber optic cable. A certain number of the distribution fibers from a particular optical splitter extend in an upstream direction of the fiber cable, and the remaining distribution fibers from that optical splitter extend in a downstream direction.
