Direct Buried (DB) tubes are tubes composed of several thick-skinned micro-tubes wrapped in a polypropylene (PP) coating. Due to the size of the micro-tubes, often made from polyethylene (PE), there is no need for an extra protective tube and so they can be placed directly under ground.
The DB-tubes are immediately usable for blowing through mini-cables, thanks to the internal longitudinal grooves. DB-tubes from Infraconcepts have a life-cycle that is comparable with optical fiber cables and they are available in various colour-compositions and diameters.
DB-tubes are mainly used in the FTTX concepts to connect homes and offices fast and flexibly. By using DB-tubes the service provider only has single-time costs for digging on the network. At a later stage optical fiber can be blowed through as required, because the tubes are furnished with a special internal skin.
The PP-coating that is easy to remove makes branching off individual tubes easier, allowing to connect individual tubes through simple, underground, connectors. The use of DB-tubes also gives the service provider a good foundation to easily expand the network in the future, as the cost of installing a few spare tubes is minimal.
DB-tubes often are an excellent alternative to HDPE-tubes. The advisors of Infraconcepts propose the optimal solution for each project.
