Optical cable

Optical cable FinMark UTxxx-SM-03-T

6

Use:
for laying in all types of soil (without cryosolic deformations), in cable-conduit lines and pipelines on bridges and pipe bridges, in tunnels, collectors at the entry to a building, including places infested with rodents, and on the exterior walls of building and structures.

Design:
Cable with a central optical module, which can contain up to 24 optical fibers. Armour layer is made from steel goffer band, and apart from providing mechanical protection, serves as a hydrobarrier preventing moisture diffusion through polymeric coatings towards optical fiber. Water-blocking band is laid between armour and optical module. External coating with a thickness of 2.7 mm is made from UV-stabilized polyethylene of high density. For additional reinforcing of construction, two strength elements are placed in external coating, they are made from steel braiding.
