AD-Tech microduct is an HDPE protective duct for fiber-optic cable, produced with a low-friction inner layer so cable can be blown over long distances. It is used on aerial, wall-mounted and buried routes in FTTX access networks.

Key features

High-density polyethylene body with a low-friction inner layer for cable blowing.
Stable inner and outer diameters for reliable connectors and joints.
UV-stabilised grades for aerial installation.
Coils in 500 m and 1000 m lengths, with custom lengths on request.

Product family

Microduct: 7/4 single tube and 14/10 assemblies

The 7/4 single microduct is made from composite polymer (PP-PA) and is designed for direct burial; its solid low-friction inner surface lets fibre or nano cable be air-blown through it, and the composite material removes the need for extra protection underground. The 14/10 assemblies come in 1 to 7-way configurations with an HDPE outer sheath, longitudinal grooves for maximum installation lengths and an integrated tracer wire under the sheath.
