What is GJYXFCH drop down fiber?

2025-09-22

GJYXFCH is a self-supporting butterfly drop cable widely used in FTTH/GPON last-mile connections. It contains 1-24 G.652D/G.657A fibers, with steel/FRP strength members and an LSZH sheath. Featuring good tensile/crush resistance and bendability, it suits indoor/outdoor aerial/duct laying. Its lightweight, tool-free stripping design enables quick installation, with low attenuation ensuring high-speed transmission in harsh environments.

Self-supporting FTTH drop cable, also known as figure-8 aerial drop cable, is designed for easy and cost-effective installation to connect end-users to the telecommunications network. As a crucial component of FTTH lines, it typically contains one or more optical fibers. Reinforced with a messenger wire, strength members, and an outer sheath, the cable delivers reliable physical performance in practical applications.

Types of Self-Supporting FTTH Flat Drop Cable

Jera offers three kinds of figure eight drop wire:

Steel wire and steel rods reinforced figure 8 cable
Steel wire and FRP rods reinforced figure 8 cable
FRP wire and FRP rods reinforced figure 8 cable

Key Advantages of Self-supporting FTTH drop cable

Self-supporting FTTH (Fiber-to-the-Home) drop cables are designed for the "last mile" of fiber networks, connecting central distribution points to end-users. Their key advantages stem from their structural design, installation efficiency, and adaptability to real-world environments, as follows:

Simplified, Cost-Effective Installation
Robust Physical Performance
Excellent Optical Transmission Stability
Flexible Routing Adaptability
Long Service Life & Low Maintenance
Safety & Environmental Friendliness
Competitive price

Applications of Self-supporting FTTH drop cable

Self-supporting FTTH (Fiber to the Home) drop cables are ideally suited for middle-span or last-mile network construction scenarios where requirements for small cable size and reliable tensile strength must be met.

In terms of core performance and configuration, this type of cable offers the following key features to adapt to diverse application needs:

Fiber Capacity & Type:It supports a maximum capacity of 4 fibers. The fiber type can be customized to G657 A1 or G657 A2 based on specific project requirements.
Strength Components: The material of the strength wires or strength rods can be flexibly selected according to different application demands.
Sheath Material & Color: The cable sheath is available in two high-performance materials: UV-resistant LSZH (Low Smoke Zero Halogen) and PVC (Polyvinyl Chloride).

How Self-supporting FTTH drop cable Installation

The installation of self-supporting FTTH (Fiber-to-the-Home) drop cables follows a standardized process tailored to their "figure-8" self-supporting structure, focusing on efficiency, safety, and optical performance protection. Below is a detailed, step-by-step guide to the core installation workflow:

Pre-installation Prep: Confirm routing (aerial/duct), check poles/brackets for stability, and prepare tools.
Aerial Suspension: Unroll the cable, fix one end to the pole bracket via the messenger wire, pull it to the next pole with controlled tension, then secure the other end.
End Processing: Strip the sheath, clean fibers, splice with connectors/adapters, and test transmission.
Indoor Routing : Route the non-messenger section through conduits/walls to the user’s ONT, then terminate and test.
