All Dielectric Self-supporting Unitube Aerial Cable (ASU80)

Structure Design

Description

Aerial Self-Supported ASU Fiber Optic Cable (for span 80m) has a loose tube structure and water-resistant gel compound to provide crucial protection for the fiber. Over the tube, water-blocking material is applied to keep the cable watertight. Two parallel fiber reinforced plastic(FRP) elements are placed on the two sides.The cable is covered with a single PE outer sheath. It is especially suitable for installation in aerial for long-distance communication.

Applications

Installation on medium and long distance LAN backbones, where a compact and robust cable is required.

Features

Easy installation

Light weight, small diameter and most economical tan ADSS cables

Span 80 to 100 meters

Fiber Core: 2-12 Core is available

Fiber Type: G652D/G655/G657A1/A2
