Application
RailOptic® SFK FO rail foot cables are suitable for the use in telecommunication systems. They are preferred for laying directly along the rail foot or other areas with vibration and impact loads. They are also suitable for laying in the ground, in trough channels and pipe conduits.
The laying of cables along the rail foot is an economical variation for cable systems for regional and branch lines, for site clearance and troubleshooting. Compared to traditional cable lines, the design and installation expense is considerably reduced, since no civil engineering work is required.
The installation can be carried out by qualified companies without special vehicles, tools and with standard rail foot clamps. The cable accessories (joints, final boxes) come from the standard program of Tyco Electronics.
Rail Optic ® SFK FO rail foot cables are universal and can be installed together with BayRail® Cu rail foot cables.
