FTTH Double-Fly Fiber Drop Cable

Optical Characteristics

Storage/Operating Temperature : -20℃ to + 60℃

FTTH Double-Fly Fiber Drop Cable is a specialized fiber optic cable designed for efficient and reliable fiber-to-the-home (FTTH) installations, particularly in residential and commercial environments. It is known for its robust construction and ease of installation, making it ideal for last-mile connectivity. Below are the key features and components of the cable:

Core Structure:

• Optical Fiber Units: The cable typically includes one or more optical fiber units, which are the core components responsible for high-speed data transmission. These fibers can be single-mode or multi-mode, depending on the specific application needs.
• Double-Fly Design: The term “double-fly” refers to the cable’s two parallel fiber optic cores arranged in a figure-eight shape. This design ensures that the cable can be easily suspended between two fixed points, such as poles or building structures, reducing the need for additional support.

Support and Strengthening Members:

• Strengthening Members: The cable incorporates strength members, such as steel wires or Fiber Reinforced Plastics (FRP), to enhance its mechanical strength. These members prevent the cable from being stretched or damaged during installation and provide additional protection against external forces.
• Steel Wire or FRP: Some variations of the cable use steel wire or FRP as a reinforcement material to ensure that the cable can withstand high tensile loads, making it suitable for outdoor installations with longer spans.

Sheath and Durability:

• Outer Sheath: The cable is typically covered with a UV-resistant, weatherproof sheath made from materials such as Low Smoke Zero Halogen (LSZH) or PVC. This sheath provides protection against environmental factors like UV rays, moisture, and temperature fluctuations, making the cable suitable for both indoor and outdoor installations.
• Weatherproofing: The LSZH sheath ensures that the cable remains safe and functional even in harsh weather conditions, while the PVC option offers additional durability in outdoor applications. The cable’s design protects against both mechanical damage and environmental stressors.

Applications:

• FTTH Networks: Ideal for use in fiber-to-the-home (FTTH) deployments, the double-fly fiber drop cable is specifically designed to connect end users to high-speed fiber optic networks.
• Residential and Commercial Installations: Its flexibility and ease of installation make it a popular choice for FTTH connections in both residential neighborhoods and commercial buildings.
• Outdoor and Aerial Installations: The double-fly design is especially useful for aerial installations, where the cable can be suspended between poles without the need for additional support structures.

Advantages:

• Easy Installation: The double-fly design makes installation simpler by reducing the need for additional hardware and support structures, cutting down on overall installation time and cost.
• Durability and Reliability: With its reinforced structure and protective sheath, the cable is designed to withstand environmental conditions and mechanical stress, ensuring long-term performance.
• High-Speed Data Transmission: The optical fiber units deliver reliable, high-speed data transmission, making this cable ideal for modern FTTH networks that require fast and stable internet connectivity.

Conclusion:

The FTTH Double-Fly Fiber Drop Cable is a versatile and reliable solution for connecting end users to high-speed fiber optic networks. With its easy-to-install design, enhanced durability, and robust performance, it is a preferred choice for both residential and commercial FTTH installations.
