Description:
The single-mode or multi-mode fiber is set into a loose tube made by high modulus plastic,and the tube is filled with water-proof compound. Loose tube is wrapped by double-sided corrugated steel tape on the outside. Water-blocking tape in the middle of the strap steel and the loose tube ensures a compact and vertical waterproof fiber optic cable. Two parallel steel wires are placed on both sides to provide the cable with high tensile strength
Features:.
--Steel wire strength, filler protect tube fiber, aluminum tape armord.
--Good ultra violet radiation resistant property.
--Good moisture-resistance.
--Fiber count: 2-12 cores.
