 Lightweight cable suitable for both overhead and underground use. Excellent bend performance and wide temperature range suitable for installation. Easy to handle for cable preparation for termination and midspan fibre access.



A lightweight cable appropriate for both overhead and underground use. Has exceptional bend performance and a wide temperature range suitable for installation. 

It needs to be PIA approved.

It should be easy to handle for cable preparation for termination and midspan fibre access. Compliant with the necessary standards for overhead and underground installation environments. Suitable for installation under overhead power lines of up and including 11kVby testing up to 15kVrms.



The Ultra Light Weight (ULW) has been developed for the requirements of the telecommunications market, it is used primarily for access, distribution, city networks, and FTTH applications. It is designed for installation in both overhead and underground environments and is approved for installation.


The below features make it an excellent solution for the requirements mentioned above.

  1. Primary coated fibre – Silica, acrylate, colour-coded fibres, fibre type G.657A1.
  2. Loose tubes, jelly-filled. Which gives excellent moisture resistance, loose tube design contains bend-resistant fibres organized in 4f, 8f,12f and 24floose tubes depending on fibre count. The tubes are easy/safe to remove for fibre preparation for splicing using standard-approved tools in the network.
  3. Water blocking element – Water blocking tape. This ensures longitudinal water-tightness and protection of inner fibre tubes.  
  4. Strength member – 2 pairs of 3 x 0.32mm brass coated steel wire strength members provided at 180° to each other. The purpose of these is to control the breaking force of cable so that cable will break in controlled conditions, for example, cable only breaks when a certain load is reached. The controlled tensile breaking load of cable is less than 2kN. Minimum tensile load= 1,350N.
  5. Ripcords – provided to enable longitudinal stripping of cable efficiently without damaging fibre elements.
  6. Sheath – Black HDPE UV stabilized with yellow stripes. Resistance to abrasion. Outer Diameter = 7.0mm. Anti-rodent protection can be added.
