Armored Tight Buffer Fiber Optic Cable With Kevlary Yarn Strength Member
Application
· Adopted to ourdoor distribution;
· Suitable for aerial, duct and direct buried;
· Long distance and local area network communication.
Characteristics
· Good mechanical and temperature performance
· High strength loose tube that is hydrolysis resistant
· Special tube filling compound ensure a critical protection of fiber
· Crush resistance and flexibility
· The following measures are taken to ensure the cable watertight:
· Steel wire used as the central strength member
· Loose tube filling compound and 100% cable core filling
· APL moisture barrier
· PSP enhancing moisture-proof
· Water-blocking material
