Key Features

Engineered For Performance

Compact Non-Armored Design

Central loose tube structure without armor layer results in minimal cable diameter and weight, ideal for congested duct environments where space is limited.

Steel Wire Reinforcement

Two parallel steel wires provide adequate tensile strength for duct pulling while keeping the cable lightweight and flexible for easy handling.

Cost-Effective Duct Cable

Simplified construction without armor reduces material costs, making it the most economical option for protected duct installations.

Water-Blocking Protection

Waterproof compound fills the loose tube and cable core, preventing moisture migration and ensuring long-term fiber performance in underground environments.

Typical Applications

01

Underground Duct Networks

Primary application in protected underground conduit where armor is unnecessary, reducing cable cost while maintaining reliable fiber performance.

02

Building Entry & Campus Links

Short-distance fiber links between buildings and campus network nodes where the cable remains within protected conduit throughout its route.

03

Access Network Distribution

Cost-effective distribution cable for telecom access networks in urban and suburban areas with existing duct infrastructure.
