Optical cable

Optical cable FinMark UTxxx-SM-02

9

Use:
For laying in all types of soil (without cryosolic deformations), in cable-conduit lines, in pipes, on bridges, in tunnels, collectors at the entry into a building, including places infested with rodents.

 

Design:
Cable with a central optical module, which can contain up to 24 optical fibers. At the perimeter of central module an armor from round steel braidings is placed. Cavities between braiding armour are filled with hydrofobic water-blocking compound. Second 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. External coating is made from UV-stabilized polyethylene of high density.
