Start with the route

Choose the construction around the installation.

Select the cable core, fibre density and level of mechanical reinforcement around the duct size, pulling method, route length and rodent exposure.

Installation method

Identify whether the cable will be pulled, blown or installed through an existing congested duct.

Capacity and duct size

Match fibre count and cable diameter to the available pathway and planned network growth.

Mechanical protection

Assess pulling load, moisture and rodent risk before choosing dielectric reinforcement or metallic armour.

Available constructions

This comparison is selection guidance, not a contractual specification. OFS Engineering confirms the final construction and guaranteed values in the approved TDS.

Customer-specific engineering

From route requirement to approved TDS.

High-performance cable is designed around the project. The online selector prepares the requirement; the approved TDS controls production.
