Seweral

Fiber-optic cables

Fiber-optic communication cable: Seweral with the central tube

Documentation

Applies to:

The optical cable is designed for laying in cable ducts, pipes, trays, blocks, tunnels, collectors, bridges and overpasses, into the ground, between buildings and structures, and also inside buildings.

 

Cable has excellent protection against rodents

 

Cable Stucture:

The cable contains an optical module with freely laid fibers.

The free space in the optical module is filled with a hydrophobic gel.

Above the module is an armor made of corrugated steel tape and a medium density polyethylene shell. The free space under the corrugated tape is filled with a hydrophobic gel. In the cable sheath, diametrically opposed are two steel wires, which serve as power elements.

Cable Structure:

The cable comprises a core of a modular design with a central power element of a dielectric rod around which optical modules with freely laid fibers are twisted. The free space in the optical modules and in the cable core is filled with a hydrophobic gel. An intermediate shell of medium density polyethylene is applied to the core. Armor made of corrugated steel tape is placed longitudinally on the intermediate shell. Between the intermediate shell and armor a hydrophobic gel is laid. The shell is made of medium density polyethylene.
