3000 meters of 4-core optical fiber communication cable

A 3000-meter 4-core optical fiber cable is a high-performance single-mode or multimode cable designed for long-distance data transmission with durability for indoor and outdoor use.

Key Specifications and Construction

• Core Configuration: 4 optical fibers, typically single-mode (OS2) for long-distance, high-speed transmission .
• Length: 3000 meters, suitable for extensive network installations .
• Cable Structure: Loose tube construction with jelly-filled tubes, central strength member (metallic or FRP), water-blocking yarns, and protective outer sheath .
• Outer Diameter: Approximately 5.8 mm for FTTH cables, compact and lightweight for easy installation .
• Sheath Material: LSZH (Low Smoke Zero Halogen) or flame-retardant materials for fire safety, compliant with IEC and EuroClass standards .
• Durability Features: UV resistance, water-blocking, and mechanical reinforcement with yarn or FRP layers to prevent damage during installation and environmental exposure .

Performance Characteristics

• Data Transmission: Single-mode fibers allow minimal signal loss over long distances, ideal for telecommunications, internet, and CATV applications .
• Environmental Suitability: Can be used both indoors and outdoors, resistant to moisture, UV, and temperature variations .
• Fire Safety: Flame-retardant and low-smoke materials reduce hazards in case of fire .

Applications

• Telecommunications Networks: Backbone connections for ISPs and telecom operators .
• FTTH (Fiber to the Home): High-speed internet delivery to residential and commercial buildings .
• Industrial and Commercial Installations: Long-distance data transmission in factories, campuses, and outdoor networks .

Summary

A 3000-meter 4-core optical fiber cable combines high-speed data transmission, long-distance reach, and robust construction for reliable performance in diverse environments. Its single-mode design, water-blocking, flame-retardant sheath, and mechanical reinforcement make it suitable for both indoor and outdoor installations, ensuring minimal signal loss and long-term durability .
