What is a subduct?
A subduct is a small-diameter polyethylene pipe buried in telecom routes or placed inside larger ducts so fibre-optic or telecom cable can run through it. It protects the cable from impact, soil pressure, moisture and rodents.
Its key advantage is that the cable route is prepared in advance, so cables can be installed or replaced later without digging again. Different colours help separate routes, operators or services.
Selection and installation
Subduct diameter is chosen from the cable diameter and installation method; enough free space inside makes pulling or blowing the cable easier. The diameter and wall combinations are in the specification table.
Uncoil the pipe without kinking and lay it on the trench bed. Cap the ends until cabling so soil and water stay out, and use dedicated subduct couplings to join lengths. This product is supplied in 100 m and 200 m coils.
Advantages of polyethylene subduct
Polyethylene does not corrode in wet or saline soil, is light, and its flexibility lets long runs follow gentle bends with few joints. Coil supply makes transport and uncoiling on site quick.
Laying several subducts in one trench or inside a larger duct reserves route capacity for future cables, minimising excavation, permit and reinstatement costs when the network is expanded.

PE Subduct — FAQ
What cables is subduct used for?
Fibre-optic and telecom cables in underground routes or inside main ducts.
Why is subduct made in different colours?
Colours separate routes, operators or cable types so the right duct is found quickly during maintenance.
How is subduct supplied?
In 100 m and 200 m coils.
Which subduct size should I choose?
It depends on cable diameter and count and the installation method. Enter the cable details in the quote form for a recommendation.
