FinMark LTxxx-SM-04 optical cable
FinMark LTxxx-SM-04 optical cable
- Cable type LT
- Design Armored
- Application Soil, in cable-conduit lines, tunnel, entering into the building
Description
Use:
For laying in 1-3 categories of soils (without cryosolic deformations), in cable-conduit lines and pipelines on bridges and pipe bridges, in tunnels, collectors at the entry into a building, including places infested with rodents, and on the exterior walls of building and structures.
Design:
Cable with 5-24 optical modules, twisted around the central strength element, they can contain up to 288 optical modules. Represents simplified version of a design LТxxx-SM-02 with smaller optical modules, which provides compactability and lesser material content of a cable. In a cable with fiber amount 4-144, optical modules are located in one layer, for larger amount – in two layer. Cavities between optical modules are filled with hydrofobic water-blocking compound. In cable with small amount of fibers, instead of missing optical modules so called «filling» modules are used. 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.
