Cable protection for optical fibre

Extena pipes for optical fibre dim ø 16-50 mm.
Also available in dim 40/29 with an extra high strength wall thickness (5.5 mm).

Optical fibre
For over 20 years, Extena has manufactured and supplied optical fibre ducting for the expansion of infrastructure throughout Sweden. Extena Cable Protection Opto is a low friction pipe with a smooth interior that can also be ordered with a silicone coating, allowing the installation of several kilometres of optical fibre cable, either by injecting air or by flushing with water.

Silicone-blended internal coating
Cable Protection Opto can also be ordered with a silicone-blended internal coating, which reduces friction between the fibre cable and pipe wall.

40/29 – extra high strength wall thickness
In addition to the standard pipe, Cable Protection Opto is also available in dimension 40/29, a special dimension with extra high ring stiffness for a safe service life in demanding environments. This product is designed primarily for wind farms and for joint pipelaying projects in rough terrain along with SRS. Demand for dimension 40/29 has increased sharply in recent years.

Approvals/Certificates
Extena cable protection pipes comply with the requirements and conditions of EBR KJ:41 and SPCR 144.
