OALC7

Alcatel has developed a complete range of fibre optic submarine cables, one of them being the OALC7 cable family. The OALC7 cable has been designed specially for repeatered systems, benefiting from our past extensive experience in the conception and development of submarine fibre optic cables.
The cable design is based on a welded steel tube, housing up to 16 fibres in a stress-free environment to ensure a long lifetime.
At the heart of the cable is the fibre unit structure where the optical fibres are set in a steel tube and are protected by a jelly from water penetration.
The composite conductor is composed of the fibre unit structure protected by a very high-strength steel wire vault, surrounded by a seam-welded copper tube swaged onto the steel wires.
Longitudinal watertightness is provided by a water-blocking material.
The composite conductor is insulated with high-density polyethylene. The insulation also provides abrasion resistance (four times more resistant than conventional insulants). This structure is used for deep-sea deployment and is our lightweight cable (LW) type.
The OALC7 cable may be used at any sea depth between 0 and 8500 meters.
Armoured cables use the deep-sea cable (LW) structure, and additional protection is provided according to the conditions and nature of the seabed.
