  "title": "Fiber drop cable assembly and method for outdoor and indoor routing",
  "abstract": "Drop cable assemblies that can be routed from an outdoor terminal directly to an indoor wall outlet without disruption, and adhered to the interior of a dwelling after removal of the drop cable jacket and utilization of a pre-applied adhesive layer are described. Additionally, telecommunications systems utilizing such assemblies, methods of routing such assemblies and methods of making such assemblies are described.",
  "claims": [
    "1. A telecommunications system, comprising: a track configured to adhere to a mounting surface of a dwelling, wherein the track comprises post features that are intermittently spaced and positioned along a length of the track to define a channel for securing and protecting a fiber drop cable, where each of the post features comprises a base end and a top end, the base end being in contact with the track and the top end extending outward away from the track, such that a longitudinal axis of each of the post features is normal to the track, wherein the post features comprise a widened cap disposed at the top end of each one of the post features, the cap having a larger cross-sectional area than the post features.",
    "2. The telecommunications system of claim 1, wherein the track and the post features comprise a flexible clear or translucent material.",
    "3. The telecommunications system of claim 1, further comprising a portion of the fiber drop cable, wherein the portion of the fiber drop cable is secured in the channel by the post features.",
    "4. The telecommunications system of claim 3, wherein the portion of the fiber drop cable is unjacketed and comprises a clear or translucent buffered fiber.",
    "5. The telecommunications system of claim 1, wherein the track and the post features comprise a flexible material that is color-matched to the mounting surface of the dwelling.",
    "6. The telecommunications system of claim 4, further comprising a cover portion positioned over the channel that provides additional protection to the unjacketed portion of the fiber drop cable.",
    "7. The telecommunications system of claim 4, wherein the unjacketed portion of the fiber drop cable includes an adhesive layer.",
    "8. A method of installing a telecommunications system, the method comprising: adhering a track to a mounting surface of a dwelling, wherein the track comprises post features that are intermittently spaced and positioned along a length of the track to define a channel for securing and protecting a fiber drop cable, where each of the post features comprises a base end and a top end, the base end being in contact with the track and the top end extending outward away from the track, such that a longitudinal axis of each of the post features is normal to the track, wherein the post features comprise a widened cap disposed at the top end of each one of the post features, the cap having a larger cross-sectional area than the post features.",
    "9. The method of claim 8, wherein the track and the post features comprise a flexible clear or translucent material.",
    "10. The method of claim 8, further comprising: inserting a portion of the fiber drop cable in the channel such that the portion of the fiber drop cable is secured by the post features.",
    "11. The method of claim 10, wherein the portion of the fiber drop cable inserted into the channel is unjacketed and comprises a clear or translucent buffered fiber.",
    "12. The method of claim 11, further comprising: positioning a cover portion over the channel to provide additional protection to the unjacketed portion of the fiber drop cable.",
    "13. The method of claim 11, wherein the unjacketed portion of the fiber drop cable includes an adhesive layer.",
    "14. The method of claim 8, wherein the track and the post features comprise a flexible material that is color-matched to the mounting surface."

  "description_excerpt": "The present description relates to a drop cable assembly that can be routed from an outdoor terminal directly to an indoor wall outlet without disruption, telecommunications systems utilizing such assemblies, methods of routing such assemblies and methods of making such assemblies.\n\nThe deployment of fiber to the home (FTTH) service is occurring at an increasingly rapid pace around the world, as service providers rush to offer greater bandwidth to customers. Installed cost is a significant concern for such service providers. Link loss is the insertion loss of the fiber span between an optical line terminal at a central office and the optical network unit at the subscriber dwelling. Additional connectors or splices are needed at the transition between cable types, and may be necessary when passing from outdoors (i.e. outside of a dwelling) to indoors (i.e. inside of a dwelling). Alternatively, a drop cable can be routed indoors within a conduit for a segment of the length, transitioned to a smaller cable with a splice or connection point, and then routed on the surface of the wall for the remaining segment. Each of these types of terminations adds to link loss, and further adds to the link budget, degrading performance and adding to electronics cost necessary for installation.\n\nIt is often necessary to drill large holes to pass a connector end of a pre-terminated drop cable through a dwelling wall. Additionally, appearance of the installed product inside of the dwelling is a key concern for homeowners and landlords. Poorly routed and stapled cables detract from a property's value.",
