Product Overview
The Loose-tube Stranded Standard Armored Optical Cable (GYTY53) is designed for outdoor optical communication networks requiring reliable mechanical protection and moisture resistance. The cable places 250 μm optical fibers inside high-modulus loose tubes filled with water-blocking compound. The tubes and filler rods are stranded around a central metallic strength member to form a compact, round core.
A polyethylene (PE) inner sheath surrounds the cable core, followed by longitudinally wrapped double-sided coated steel tape (PSP) and a PE outer sheath. This structure provides additional protection against crushing, moisture penetration, and external mechanical stress.
Product Features
- Armored Construction: Double-sided coated steel tape provides additional mechanical protection for outdoor cable routes.
- Water-Blocking Design: Water-blocking compound inside the loose tubes and cable core helps limit moisture penetration.
- Reliable Fiber Protection: High-modulus loose tubes offer good hydrolysis resistance and mechanical strength.
- Good Crush Resistance: The armored structure helps protect optical fibers against external pressure.
- Temperature Stability: Designed to provide reliable mechanical performance across operating temperature variations.
- Durable Outer Sheath: The PE sheath provides environmental protection for outdoor installations.
Applications
- Outdoor telecommunications backbone networks
- Optical fiber trunk lines
- Telecommunications infrastructure requiring armored cable protection
- Outdoor fiber optic installations exposed to mechanical stress
