GJXH type 4-core optical fiber cable

GJXH type 4-core optical fiber cable is a versatile fiber optic solution designed for both indoor and outdoor applications, featuring four single-mode fiber cores with robust mechanical protection.

Overview

The GJXH 4-core fiber optic cable is widely used for Fiber-to-the-Home (FTTH), Fiber-to-the-Building (FTTB), and industrial network installations. It consists of four single-mode fiber cores enclosed in a protective jacket that ensures durability against environmental factors such as moisture, UV radiation, and temperature variations . The cable is suitable for both indoor and outdoor deployment, depending on the variant chosen.

Construction and Features

• Fiber Cores: Contains 4 single-mode fibers for high-speed data transmission .
• Reinforcement: Some variants, like the GJXH-4B6, feature metal-reinforced jackets for enhanced tensile strength, rodent resistance, and mechanical durability, making them ideal for metal entry and aerial applications .
• Sheath Material: The outer jacket can be UV-resistant white for outdoor use or LSZH/PVC for indoor safety and flame retardance .
• Central Strength Member: Typically includes fiber-reinforced plastic (FRP) or steel wire to provide structural support and prevent fiber damage during installation .
• Loose Tube Design: The fibers are often housed in a loose tube or bow-type configuration, which protects them from bending stress and simplifies splicing .
• Low Signal Attenuation: Ensures stable and efficient communication over long distances .
• Compatibility: Works with standard fiber optic termination and connector equipment .

Applications

• Outdoor Telecommunications: Metal-reinforced GJXH cables are suitable for aerial installations, metal entry points, and harsh environmental conditions .
• Indoor Cabling: Non-metallic, LSZH variants are ideal for indoor risers, ducts, and safe-zone installations, providing flame retardance and EMI immunity .
• FTTH/FTTB Deployments: Supports last-mile connectivity with high bandwidth and reliable signal transmission .
• Industrial Networks: Can be used in factories or outdoor industrial environments requiring robust mechanical protection .

Installation Considerations

• Flexibility: Lightweight and flexible design simplifies installation in both aerial and entry-point scenarios .
• Environmental Protection: UV-resistant and rodent-resistant jackets enhance longevity in outdoor deployments .
• Customization: Some suppliers allow custom branding and length-specific orders, which is useful for large-scale projects .

Summary

The GJXH type 4-core optical fiber cable combines high-speed single-mode fiber transmission with mechanical durability and environmental protection, making it a reliable choice for a wide range of indoor and outdoor network applications. Variants with metal reinforcement are ideal for outdoor and aerial use, while LSZH or PVC jackets suit indoor installations, ensuring safety and compliance with fire regulations .
