Unitube Multi Core Digital Fiber Optic Cable 4F To 24F PBT GYFXTY
Unitube Multi Core Digital Fiber Optic Cable 4F To 24F PBT GYFXTY
Description
The cable includes placing fibers inside a loose tube made of high modulus plastic, which is then filled with
a water-resistant compound. This tube receives additional protection from a water-blocking system layer.
Two parallel FRP components are positioned on either side of the assembly. Ultimately, the cable structure
is finished off with a polyethylene (PE) sheath.
Application
This specification outlines the essential criteria for a Central Loose Tube Outdoor Cable designed for aerial
or duct installations.
Characteristics
* Reliable mechanical and temperature performance.
* Hydrolysis-resistant high-strength loose tube.
* Special tube filling compound ensures critical fiber protection.
* Combination of crush resistance and flexibility.
* FRP enhances tensile strength.
* Compact, lightweight, and easy installation-friendly due to its small diameter.
