Cablu de fibra optica single mode TYPE 24 PE

Outdoor Central tube Optical Fibre Cables metal-free, max. 24 fibres
Application
  • For outdoor use in structured (data) wiring systems (campus backbone)
  • For outdoor use in networks for telecom, cable TV and/or broadcast.
  • Easy to install in ducts, tunnels, trenches and/or tubes (by means of compressed air or pulling wire).
Suitable for direct burial (crush ≤150 N/cm).
Key features
  • A simple all dielectric cable construction (and consequently more cost-effective up to 24 fibres then multi-tube cables) with standard rodent protection.
  • Predicted lifetime > 30 years.

    13 – 24: red - natural - yellow - blue - green - violet - brown - grey - orange - turquoise - pink
    and white with black rings.
  • 3. Swellable (for the longitudinal watertightness) yarns as strength members and for the standard rodent protection.
  • 4. Black UV resistant PE outer jacket.
    Identification: BELDEN OFC – "cable type" – "number x type of fibre" + date-, meter- and P/N- marking.

Guide to installation and handling
 • When laying and installing optical fibre cables it is vitally important not to exceed the specified
values set for pulling tension, bending radii and temperature. The installation methods have to be
in accordance with the common standards.
 • To ease insertion into tubes by means of compressed air or pulling wire, certified lubricants (e.g.
paraffin) may be used. The use of soap or similar substances as lubricants is strictly prohibited.
 • If a cable needs to be fastened, constrictions ≥ 1 mm must be prevented.
 • The jelly filling inside the tubes can be removed using a tissue soaked in turpentine.
 • It is advisable to cap the cable-ends during storage.
Options
 • Cables from 1 to 24 fibres.
 • Universal (halogen-free) cables for outdoor and/or indoor use.
 • Non-standard cable constructions, colours, details and/or additional information regarding specifications are available on request.
