Single Mode Central Loose Tube Armored 4 6 8 12 Core GYXTW

Description

In this cable design, optical fibers are housed within a loose tube composed of high modulus plastic, and

this tube is thoroughly filled with a water-resistant compound. To enhance the cable's structural integrity

and water resistance, a layer of corrugated steel tape is wrapped around the tube. Water-blocking material

is strategically applied between this corrugated steel tape and the loose tube. Two parallel steel wires are

situated on either side of the steel tape for additional support. The entire assembly is finalized with a prote-

ctive polyethylene (PE) sheath, completing a robust and watertight cable structure.

Application

This specification outlines the fundamental requirements for Central Loose Tube Outdoor Cable designed

for aerial or duct installations.
