Gjxh Fiber-to-the-home cable

GJXH is a specialized FTTH drop cable designed for indoor and outdoor use, offering high bandwidth, flexibility, and durability for direct fiber connections to end-users.

Overview

GJXH cables are indoor and outdoor drop fiber optic cables used to connect fiber networks directly to homes or businesses. They are commonly deployed in FTTH, FTTO (Fiber to the Office), and FTTB (Fiber to the Building) applications . The cable supports single-mode fibers (G652D or G657A), providing high-speed data transmission suitable for streaming, gaming, and large file transfers .

Construction and Design

• Shape and Structure: GJXH cables often feature a butterfly or bow-shaped flat design, making them lightweight, flexible, and easy to route through indoor conduits or along walls .
• Strength Members: Two parallel steel wires or KFRP rods are placed on either side of the fiber to provide crush resistance and tensile strength, protecting the fiber during installation and operation .
• Sheath Material: The outer jacket is typically LSZH (Low Smoke Zero Halogen), flame-retardant, and safe for indoor environments. Some variants use HDPE for outdoor protection against moisture, UV, and temperature extremes .
• Fiber Protection: The loose tube or low-bend-sensitivity fiber design ensures stable transmission and reduces stress from mechanical strain or temperature changes .

Features

• High Bandwidth: Supports gigabit and higher-speed data transmission.
• Easy Installation: Lightweight, flexible, and compact, allowing rapid deployment from distribution boxes to end-user terminals .
• Durability: Reinforced with steel wire or aramid yarn for tensile strength and crush resistance.
• Flame Retardant: LSZH jacket meets fire safety standards for indoor use.
• Cost-Effective: Flat design reduces material and installation costs compared to traditional round cables .

Applications

• FTTH Networks: Direct fiber connection to homes for broadband internet.
• FTTO/FTTB: Fiber connections to offices or multi-dwelling units.
• Indoor Wiring: Ideal for backbone and horizontal distribution in buildings.
• Self-Supporting Installations: Some GJXH variants include a high-carbon steel messenger wire for spans up to 50 meters without additional support .

Installation Considerations

• Traction Force: Manual pulling should not exceed 80% of the cable's allowable tension, with momentary peaks under 100N .
• Splicing and Maintenance: Simple structure and good strippability make splicing and maintenance straightforward .
• Customization: Some manufacturers offer custom packaging and logo printing on drums for branding purposes . GJXH FTTH cables are a reliable, flexible, and high-performance solution for modern fiber optic networks, combining ease of installation with robust protection and high-speed data capabilities. They are widely used in residential, commercial, and enterprise fiber deployments.
