48-core optical fiber cable gyfty

A 48-core GYTS fiber optic cable is an outdoor, steel-armored, loose-tube cable designed for duct, aerial, and direct burial applications, supporting high-bandwidth, long-distance data transmission.

Overview

The 48-core GYTS fiber optic cable is primarily used for outdoor telecommunications and backbone networks. It is suitable for duct, aerial, or direct burial installations, providing robust protection against environmental hazards, mechanical stress, and rodents . The cable is available in single-mode (G.652D or bend-insensitive G.657A1) and multimode variants, allowing flexibility depending on network requirements .

Structure and Components

• Loose Tubes: Fibers are housed in gel-filled loose tubes, allowing free movement to minimize stress during bending or stretching .
• Fiber Count: Contains 48 color-coded fibers, facilitating easy identification and high fiber density within a compact design .
• Central Strength Member: A steel wire provides tensile strength and strain resistance, ensuring durability under tension .
• Armor: Corrugated steel tape (CST) or plastic-coated steel tape (PSP) surrounds the core, offering crush resistance, impact protection, and rodent deterrence .
• Outer Sheath: A polyethylene (PE) or UHMWPE jacket protects against moisture, UV exposure, and environmental wear .

Key Specifications

• Tube Thickness: Approximately 0.3 ± 0.05 mm
• Fiber Diameter: 242 ± 7 µm
• Cladding Diameter: 125 µm
• Cable Diameter: Around 10.5 ± 0.2 mm
• Jacket Thickness: 1.8 ± 0.2 mm
• Steel Tape Thickness: 0.15 ± 0.015 mm
• Installation Length: Standard drums of 2 km, customizable per project

Advantages

• High Mechanical Protection: Steel armor and metal strength member prevent crushing and tensile damage.
• Moisture Resistance: Gel-filled tubes and PE sheath protect fibers from water ingress.
• Stress-Free Fiber Movement: Loose tube design allows fibers to expand and contract without damage.
• Long-Distance Transmission: Suitable for backbone networks and high-bandwidth applications.
• Versatile Installation: Can be deployed in ducts, aerial setups with messenger wires, or direct burial .

Applications

• Telecommunication Backbone Networks
• Long-Haul Data Transmission
• Outdoor LAN and Metropolitan Area Networks (MANs)
• Industrial and Utility Networks The 48-core GYTS cable is a reliable choice for projects requiring durable, high-capacity fiber infrastructure in challenging outdoor environments, combining mechanical strength, environmental protection, and high-performance optical transmission .
