gabo Systemtechnik Laying instructions 22 speed•pipe® indoor Network level 4 Requirements: • The cable diameter should be within the specified diameter ranges (see table): • The cable diameter has a considerable influence on the blowing in length. • Because of the various influencing factors during the installation of speed•pipe® indoor in buildings, the different cable constructions and the various methods of introducing the cables into the pipes, the following rules should be taken into account when planning pipe systems for fibre optic networks in buildings: In the interior the cables should have a preferably small diameter. The central support elements of the cables should have a preferably small diameter, to allow a greater flexibility. The routing of several cables with a lower number of fibres is preferable. • When selecting the indoor cables take care that the cable has a longitudinal stiffness which can transmit the axial forces of the slide-in unit well. If the cable has a central support element, this is to be suitably made flexible on the first 50 mm (e. g. breaking the fibre fabric). • The cable diameter should be even and should not fluctuate by more than 0.3 mm. • The cable jacket should be as smooth as possible. • The outer surface of the cable should be dry and clean and should not exceed a temperature of 25 °C (ideally 15 °C). • Ideally the cable is optimized for speed•pipe® indoor and certified on a test track. • The cable should not show any lateral run-out.
