Products Products Miniature plastic protective tubes Miniature plastic protective tubes CJSC PLASTKOM has mastered the production of miniature protective plastic tubes (MZPT) for the construction of distribution access networks (FTTH) of various architectures (P2MP, P2P) based on small-sized optical cables. A feature of creating access networks based on MZPT and small-sized OK is the stage-by-stage construction of such networks. At the initial stage, a cable infrastructure is created - an individual cable channel made of MZPT protected from external influences with a diameter of 5 to 10 mm, as close as possible to the subscriber. As protection from external influences, ZPT with an outer diameter of 20 mm to 63 mm are used, into which MZPT are laid. In the future, as subscribers appear, a small-sized optical cable with a diameter of no more than 6 mm with a given type and number of optical fibers (from one to several tens of optical fibers) is laid. Main standard sizes of ZPT Outside diameter / wall thickness, mm Application features and gaskets 5 / 0.75 Creation of a cable infrastructure for a vertical optical system of access to subscribers of multi-storey buildings using OCs with a diameter of up to 2 mm. The laying is carried out by the method of alternately pulling through the MZPT in the riser from the ZPT, in a flame retardant design. The number of MZPT: in the RRT with a diameter of 20 mm - 6 pcs., In the RRT with a diameter of 25 mm - 10 pcs. 7 / 0.75 and 10 / 1.0 Создание горизонтальной кабельной инфраструктуры для сетей доступа FTTH с использованием ОК диаметром до 6 мм.
