Key Features

Engineered For Performance

Cost-Effective Burial Cable

Light armor design provides adequate protection for direct burial at lower cost than double-armored alternatives like GYTA53, ideal for budget-conscious projects.

Glass Yarn Anti-Rodent Layer

Glass yarn layer between inner and outer sheaths effectively deters rodent gnawing, providing reliable protection in underground environments.

Steel Tape Armor

Corrugated steel tape provides good crush and impact resistance for direct burial deployment while maintaining moderate cable weight.

High Fiber Capacity

Stranded loose tube design supports up to 144 cores, suitable for medium to high-capacity trunk and distribution networks.

Typical Applications

01

Direct Burial Networks

Cost-effective direct burial option for telecom networks where moderate mechanical protection is sufficient and double armor is unnecessary.

02

Duct Installation

Underground conduit deployment for metro and suburban fiber networks, leveraging the cable's anti-rodent protection and mechanical strength.

03

Suburban & Rural Telecom

Distribution and trunk fiber routes in suburban and rural areas where direct trenching provides the most economical installation method.
