MIKROHARD microtubes
Single wall protective pipes MIKROHARD are designed for modern microduct technology used in FTTx (Fibre-to-the-X) optical networks.
- microducts can be installed in existing HDPE protective pipes (MIKROHARD DI) or directly buried in the ground without the need for an additional protective pipe (MIKROHARD DB)
- different numbers of microducts can be installed inside OPTOHARD protective pipes depending on their inner diameter and the outer diameter of the microducts
- the required number of microducts depends on the number of optical fibres in the installed microcables
Design
- standard (DI) - inner wall grooved, outer wall smooth
- hardened (DB) - inner wall grooved, outer wall smooth
Material
- high-density polyethylene (HDPE)
- with UV stabiliser on request
Colour
- according to RAL
Heat resistance
- handling temperature: +5 ºC to +50 ºC
- operating temperature: -40 ºC to +70 ºC
- storage temperature: -40 ºC to +60 ºC
Standard primary microtubes (DI)
- designed for installation in existing OPTOHARD protective pipes, both empty and partially occupied
- microducts can be installed by blowing or pulling over shorter distances

- designed for installation in trenches during the construction of new access netqorks without additional protective pipes
- the reinforced wall structure and mechanical properties of these microducts provide reliable protection for optical microcables
