Optical fiber drop cable, also known as FTTH (Fiber to the Home) cable, serve as the critical final segment in fiber optic network. These cable bridge the gap between an ISP’s backbone infrastructure and end-user premises, enabling high-speed internet, voice, and data service in residential, commercial, and industrial settings. As the cornerstone of last-mile connectivity, understanding their design, capabilities, and applications is essential for deploying efficient FTTH solution.
Key Characteristics of Fiber Drop Cable
1.Compact Design & Lightweight Construction
Drop cable are engineered for flexibility and ease of installation, featuring a slim profile with 1–4 optical fiber (occasionally up to 12 for specialized needs). Their lightweight design facilitates seamless routing through tight spaces, making them ideal for both indoor and outdoor environment.
2.Superior Bending Performance
Designed to withstand minimal bending radii without signal loss, these cable excel in challenging installations, such as through walls, conduits, or overhead pathways. This flexibility ensures reliable performance in complex network layouts.
3.Robust Reinforcement & Protection
4.Flame-Retardant Materials
Indoor drop cable often feature LSZH (Low-Smoke, Zero-Halogen) jackets, meeting fire safety standards for indoor use by minimizing toxic fumes and smoke in case of fire.
Major Types of Fiber Drop Cable
| Type | Key Features | Ideal Use Cases |
| Indoor FRP Drop Cable (GJXFH) | FRP reinforcement, 1–4 fibers, LSZH sheath, non-conductive. | Homes, offices, MDUs (indoor-only). |
| Outdoor Flat Steel Drop Cable (GJXH) | Flat figure-8 design, steel wire reinforcement, water-resistant sheath. | Aerial installations, outdoor ducting. |
| Self-Supporting Figure-8 Cable (GJYXCH) | Pre-terminated factory connections, integrated steel suspension. | Fast FTTH deployment, outdoor-to-indoor links. |
| Armored Duct/Aerial Cable | Heavy-duty armor, multi-fiber capacity (up to 12 fibers), UV/EMI resistance. | Metropolitan networks, long-distance trunk lines. |
| Outdoor Flat Drop Cable | Compact design, single or dual fibers, weatherproof sheath. | Direct outdoor routing in low-interference areas. |
Application Scenarios for Fiber Drop Cable
1.Indoor Residential & Enterprise Setups
2.Building Infrastructure Wiring
Horizontal Wiring: Low-tensile cables suffice for short-distance routing within walls or ceilings.
Vertical Cabling: Requires cables with higher tensile strength (e.g., steel-reinforced designs) to withstand gravity and meet fire retardancy codes.
3.Overhead Aerial Installations
Figure-8 Self-Supporting Cables: Feature an integrated steel suspension wire, enabling secure overhead placement from utility poles to buildings. Ideal for outdoor-to-indoor transitions, these cables simplify installation and reduce costs.
4.Duct & Underground Laying
Duct-Compatible Cables: Designed with rigid sheaths and water-blocking layers, these cables thrive in underground conduits, providing protection against moisture, rodents, and mechanical stress. Not suitable for direct burial without additional shielding.
