Mechanical cable reinforcement
High strength and modulus protect optical fibres during installation, bending and service. The material is a load-bearing element, not a replacement for the optical core.
Optical cable
A strength member that does not conduct electricity
Para-aramid is used as a central strength member, braid and reinforcing component in optical cable. It carries mechanical loads while preserving the dielectric properties of the construction.
01 — ROLE IN THE PRODUCT
How each material works
The material is selected by its function in the structure. The same product may require different fibres depending on the environment and load.
02 — APPLICATIONS
Where the yarn is used
Central strength member
A load-bearing component inside the cable for tensile loads.
Aramid braid
Distributed reinforcement around optical modules and cores.
Self-supporting cable
Strength and armour elements for constructions with higher mechanical requirements.
Suspension and finished assemblies
High-strength cable suspension and partner finished or semi-finished solutions to specification.

What the material offers
- High strength and modulus at low weight
- Electrical insulation
- Heat, abrasion and chemical resistance according to the catalogue
- Several dtex/f options for different constructions
Mandatory checks
- UHMWPE is not the primary material for this segment
- Tension and elongation during installation must be checked
- Extrusion temperature and bend radius are important
- Fire safety is assessed on the finished cable
05 — SELECTION AND PILOT
Four inputs for a technical inquiry
The more precise the inputs, the fewer unnecessary samples and the faster the comparison with the incumbent material.
ComponentCentral member, braid, rope, sleeve or harness
MechanicsTension, elongation, bending, fatigue and load
ProcessFeed tension, extrusion, temperature and line speed
AcceptanceTests on yarn and finished cable assembly
