MIKROHARD microtubes

MIKROHARD microtubes
Single wall protective pipes are designed for the latest technology used for optical networks FTTx (Fibre-to-the-X) micro technology.
- microducts can be used for installation in an existing ducts of PE-HD tubes (MIKROHARD DI)
- for direct installation in the ground without the use of additional protective tube (MIKROHARD DB)
- various quantities of microtubes can be installed inside OPTOHARD protectors depending on the inner diameter of the protector and the outer diameter ot the microtube (these quantities are derived from the need to install microcables with vyrying numbers of optical fibres)
Tube design
- standard (DI) - are produced with an inner wall - smooth or grooved, with sliding layer
- hardened (DB) - are produced with an inner wall - smooth or grooved, with sliding layer
Material
- high-density polyethylene (PE-HD)
- with UV stabiliser on request
Standard primary microtubes (DI)
- these are designed for installation into existing OPTOHARD protective tubes, both empty and partially full
- installed by blowing or pulling for shorter distances

- for installation into trenches when constructing new access networks without additional protective tubes
- the reinforced walls and mechanical properties of these microtubes ensure adequate protection for optical microcables
