Microduct Assembly 7/3.5 mm

TWD 7/3.5 mm 1-24 -way S12

  • For direct burial
  • 1, 2, 4, 7, 12, 19 or 24 bundled ducts
  • 7/3.5 mm microducts
  • Low friction inner surface
Three different versions of indoor microduct assemblies in different colours

The thick walled microduct bundles consist of a number of microducts with an inner low friction surface that enables installation of air-blown fiber units or nano cables. The thick inner wall of the microducts allow for installation directly into the ground without the need for additional protection.

The duct assemblies are available in several configurations from 1 to 24 microducts.

7/3.5 mm microducts are optimized for installation of air-blown fibers and nano cables. The microducts have a solid low-friction innner surface for best blowing performance.

Marking Duct assemblies have markings showing the type and tube length. The individual microducts are identified by their colors.
12 different colors are used according to the S12 standard.
For duct assemblies with >12 ducts, the first 12 colored ducts are marked with “1” and the following ducts are marked with “2”.
The assemblies are available in various sheath colors for easy identification.
