These cables are used for outside plant and consist of up to 12 singlemode (SM 9/125) fibre or multimode (MM 62.5/125 or MM 50/125)fibres.

This type of cable is the centre loose tube construction. The Loose Tube components are manufactured from high strength, low shrinkage PBT compound, and the tube will contain optical fibers. The loose tube also contains a thixotropic jelly, to prevent water penetration and protect the fibers against shock. A corrugated steel tape (0.15mm thick and with a 0.05mm copolymer coating on both sides) is then applied longitudinally over the loose tube. Between the steel tape and the loose tube, waterblocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape. Finally the cable is completed with a black polyethylene (PE) sheath.

These cables are used for indoor applications and consist of 4, 6, 8,
12 single-mode (SM 9/125) fibre or multimode (MM62.5/125 or MM50/125) fibres. Each fibre is coated to a 900 micron diameter, with a durable, protective material and the coating (buffer material). Each fibre is uniquely colour coded as defined in Table 1. Surrounding the group of buffered fibres are aramid yarns to provide the sufficient tensile strength to the cable, which effectively avoids damaging the cable during the installation, transports, operation etc. An outer sheath is then applied over the tight fibre / aramid assembly. The outer sheath has a flame retardant function, PVC (Riser OFNR).
