High Density Polyethylene (HDPE) tubes are thick-skinned tubes that are optimised to blow conventional optical fiber cables through over longer distances. In case several cables must be blown through an HDPE-tube, conducting tubes are applied inside the HDPE-tube. A conducting tube can be supplied separately, or be combined with the HDPE-tube on ordering (so-called prefab HDPE-tube). A conducting tube is also made from HDPE material, but it has a thinner skin.
Thanks to their low friction, the HDPE-tubes and conducting tubes can be directly used to blow through optical fiber cables. This is achieved through internal longitudinal grooves or an extra smooth inner coating. HDPE-tubes from Infraconcepts have a life-cycle that is comparable to optical fiber cables, and they are available in various colour-combinations and diameters.
HDPE-tubes are generally used on networks where multiple optical fiber cables are installed between main locations. The HDPE tube takes care of both protecting the optical fiber cable and of the possibility to blow through optical fiber cables over long distances. Conducting tubes are often used to upgrade existing routes (by using mini-cables), where there might be, for example, a conventional optical fiber cable already in an HDPE-tube, or where there’s an empty HDPE-tube.
Also thinner HDPE-tubules are used in FTTH-projects to protect optical fiber over the last mile to realise the home-connection. Prefab-solutions (HDPE-tube with pre-mounted conducting tubes) are still used in client-specific concepts, but they are generally substituted by a DB-tube combination in the customer concept.
