Key Features

Engineered For Performance

Triple-Layer Protection

APL moisture barrier, corrugated steel tape, and round steel wire armoring provide the highest level of mechanical and environmental protection available.

Extreme Tensile Strength

Round steel wire armor delivers tensile strength up to 20000N short-term, suitable for underwater crossings and steep terrain installations.

Superior Crush Resistance

8000N/100mm short-term crush resistance protects fibers under extreme mechanical loads from heavy vehicles, rocky soil, and underwater pressure.

Waterway Crossing Capability

Heavy-duty construction with comprehensive waterproofing enables deployment across rivers, canals, and other water crossings without additional protection.

Typical Applications

01

River & Canal Crossings

Underwater fiber routes crossing rivers, canals, and streams where extreme tensile strength and waterproofing are essential for cable survival.

02

Heavy-Duty Direct Burial

Burial in challenging terrain including rocky ground, road crossings, and areas with heavy vehicular traffic requiring maximum mechanical protection.

03

Industrial & Mining Environments

Fiber deployments in industrial sites and mining operations where cables face extreme mechanical stress and harsh environmental conditions.
