Non-Armored Uni-Tube optical cable with fibers placed in loose buffer tube.The cable core is protected with jelly to prevent water intrusion and migration, and cover with a black polyethylene out jacket. Two embedded FRP or metallic wire provide desire tension.
1. Small size, Low cost.
2. the fiber counts is up to 24 fibers.
3. Uni-tube gel-filled construction for superior fiber protection.
4. Two parallel FRP wire and overall glass yarn to enhance tensile
resistant.
5. And protect cable from mechanical damage.
6. Designed for use with inexpensive attachment hardware.
7. Self-supported no messenger needed.
