Definitions

  • the present invention relates to a communications cable.
  • the cable is suitable for deployment in outdoor locations.
  • each one of said optic fibres includes an inner core and an outer jacket encasing the inner core.
  • the fibre optic cable has a diameter of approximately 5mm.
  • the fibre optic cable includes up to 12 individual optic fibres.
  • Figure la is a side perspective view of a communications cable
  • Figure 3b is an end perspective view of an alternate communications cable.
  • Cladding coatings may be applied, in the described embodiment, by passing the fibre through a primary coating stage, performing UV curing of the resulting first layer, and then repeating this coating and curing process for the secondary layers.
  • the fibre may be subjected to primary and secondary coating phases before experiencing curing.
  • Concentric fibre first and second coatings are applied with typical thicknesses of 125 ⁇ and 50 ⁇ respectively. The coatings serve to maximise fibre strength and minimise signal attenuation in the presence of stresses.
  • the coated optical fibres 14 are packed tightly together in a compact structure, referred to as a loose tube.
  • the coated fibres 14 may be arranged in a helical configuration to reduce fibre stress during stretching of the cable 10 or in response to temperature changes.
  • Flexible fibrous polymer strength members such as Aramid yarn or Twaron, 204 are wrapped around the inner tube 203 for physical protection.
  • the optical base cable 12 preferably includes additional protective layers 203 and 205 which may be comprised of fluoropolymers, such as polyvinylidene, polytetrafluoroethylene or polyurethene, or a light-weight glass material.
  • the furcation tubes 22 are preferably 2.0mm in diameter and may comprise of an inner tube for housing the 250 ⁇ buffered optical fibre 14, an inner protective layer of Aramid yarn, and an outer protective layer constructed from polyvinyl chloride (PVC), LSZH, or another material providing similar durability, robustness and flexibility properties.
  • the furcation tubes may each contain a pull string constructed from materials such as Aramid yarn.
  • Each individual optical fibre furcation tube 22 may be used as a patch cable to provide data connectivity to the intended termination application. Connection of each furcation tube 22 at the application destination may be achieved by the use of a common connector type, such as Avio, ADT-UNI, DMI, EC, ESCON, FC, SC, SCA, ST, LC, MTRJ, SMA, and other variants known to persons skilled in the art. In other embodiments the furcation tubes 22 may be connected to a terminal using fibre optic path panels, or an optical distribution frame. The optical fibres 14 housed by the furcation tubes 22 may alternatively be extended by connection to other optical fibres by splicing.

Abstract

On décrit un câble de communications, notamment un câble à fibres optiques qui comprend: une pluralité de fibres optiques pouvant chacune agir comme un guide d'ondes optique; une couche de gaine extérieure enveloppant le câble à fibres optiques; et un ensemble de branchement agencé à une extrémité du câble à fibres optiques et assurant un accès distinct à chacune desdites fibres optiques.
