Product Description


Long-distance outside plant telephony, CATV as well as data communications.

Direct burial and installation in ducts either by pulling or blowing methods.

Aerial installation using the Figure-8 self-supporting option.

High fibre counts indoor installations.


The cable consists of 5 to 36 elements stranded in up to 3 layers around a central strength member and bound in a jacket. The elements are usually fibre-containing tubes, however fillers are also used when needed, to preserve cable geometry. The cables can be ordered with a central member either made of a dielectric FRP, solid or stranded steel coated with polyethylene. The tubes and fibres are colour coded. Two to 24 color-coded fibres are loosely laid in each tube. Maximum fibre count is 864. Standard tube diameters are:

  • 2.1 mm – up to 12 fibres/tube – LDB sub-series
  • 2.5 mm – up to 24 fibres/tube – LDC sub-series
  • 2.8 mm – up to 24 fibres/tube – LDD sub-series
  • 3.1 mm – up to 24 fibres/tube – LDE sub-series

In addition to our All-Dry (gel-free) DRC Cables, a variety of cable water-blocking options is available: gel filling in the tubes, core and/or between jacket layers, or dry water-blocking tapes or yarns in the tubes, core and/or between jacket layers. A ripcord is located under each jacket layer to facilitate its removal.

A wide range of jacket and armouring options is available: PE, FR-LSZH (HFFR) materials, corrugated steel armouring, steel wire and steel braid armouring, fiberglass armouring, aramid yarns, anti-termite etc. A Fig-8 self-supporting design is also available for all fibre-counts.
