Description
Use:
For laying in 1-3 categories of soils (without cryosolic deformations), in cable-conduit lines and pipelines, with a possibility of distant power feed.
Design:
Cable with 1 – 4 optical modules, which can contain up to 24 optical fibers, and 2 (4) insulated copper conductors diameter 1.2 mm for distant power feed, twisted around the central strength element. Represents a modification of design LТxxx-SM-02. Cavities between optical modules and copper conductors are filled with hydrofobic waterblocking 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.
