Key Features

Engineered For Performance

Double Armor Protection

Corrugated steel tape combined with aluminum polyethylene laminate (APL) provides the highest level of mechanical protection for direct burial without conduit.

Rodent Resistant

Steel tape armor layer effectively prevents rodent damage, ensuring cable integrity in underground environments where rodent activity is common.

Superior Moisture Barrier

APL moisture barrier plus waterproof compound filling provides comprehensive water ingress protection for decades of reliable underground performance.

Heavy-Duty Crush Resistance

Double armor construction delivers exceptional crush resistance of 3000N/100mm, protecting fibers from soil pressure and external mechanical loads.

Typical Applications

01

Direct Burial Installation

Primary application for directly buried fiber routes without protective conduit, where double armor provides the mechanical protection of a duct system.

02

Harsh Underground Environments

Rocky terrain, high water table areas, and locations with significant rodent activity where maximum cable protection is essential.

03

Long-Distance Telecom

High-capacity backbone and trunk lines for inter-city and rural telecom networks deployed via direct trenching for cost-effective installation.
