Description

Fiber optic cables.


Recommended laying conditions - in soils of all groups when laying in a trench, groups 1 - 3 when laying with a knife cable layer, including soils subject to permafrost deformations and laying, through swamps, lakes and rivers with a maximum depth of no more than 10 m. For laying, taking into account the volume combustible load of cables, in open cable structures

 

Brand design

1. The central power element is metallic or dielectric.


2. Optical fiber.
3. Optical module - polybutylene terephthalate.
4. Optical modules are located around the CSE.
5. Filling - hydrophobic compound or water - blocking threads and tapes.
6. Type A casing:
- aluminum polyethylene tape with a polyethylene coating;
- shell - polyethylene or composite polymer material.
7. Outer cover type 2 K:
- double - layer armor - galvanized steel wires coated with hydrophobic gel;
- sheath is a material that does not spread combustion during group laying.
