Description
Optical cable FinMark LTxxx-SM-18-2×1.2CW, LTxxx-SM-18-4×1.2CW Designed for hanging on supports of communication lines and electric power supply lines, between houses and other objects, with a possibility of distant power feed.
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-18. 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. External coating is made from UV-stabilized polyethylene of high density. Carrying strength element is made from zinc-coated twisted wire rope, which provides for cable a high resistance to longitudinal stress.
