Indoor Outdoor FTTH Armored Round Fiber Optic Drop Cable, single core double sheath spiral armoured

The Indoor Outdoor Spiral Armored Round Fiber Drop Cable is a fiber optic cable designed for the "last mile" connection in fiber-to-the-home (FTTH) deployments. It addresses environmental adaptability issues through a "double-layer sheath" and provides physical protection through "spiral armor," enabling a seamless, robust, and reliable connection from outdoors to indoors with a single cable. Although its cost is higher than ordinary drop cables, it offers the optimal solution for scenarios with harsh deployment environments, difficult maintenance, or extremely high network reliability requirements.

Features and Advantages

* All-weather adaptability (Indoor/Outdoor):

1. Outdoor side: HDPE layer resists UV rays, rain, and extreme temperatures (typical operating temperature: -40°C ~ +70°C).

2. Indoor side: Flame-retardant layer ensures low smoke and halogen-free performance in case of fire, protecting personnel safety.

Value: Enables single-cable deployment without the need for splice boxes, reducing failure points and lowering construction costs and losses.

* Excellent mechanical and biological protection (Spiral Armored):

1. Rodent/Termite protection: The armored layer is one of the most effective barriers against physical gnawing by rodents and termites.

2. Compression and impact resistance: Can withstand trampling, compression, and soil pressure during installation and use.

3. Tensile strength: Combined with the central strengthening member, it can withstand high installation tensile forces.

4. Cut resistance: Provides extra protection against accidental digging by garden tools or construction damage.

* Excellent flexibility and ease of installation (Round & Spiral):

1. The round structure is easy to pass through standard conduits and sealing sleeves.

2. Spiral armor is softer than longitudinally wrapped armor, with a smaller bending radius, making it easier to handle around corners.

3. Relatively moderate weight, suitable for various laying methods such as aerial, duct, and direct burial.

* High reliability:

Robust structure with no joints throughout, significantly reducing the risk of network interruptions.

Application:

* Rural/Suburban FTTH:  The cable is routed overhead from utility poles, across yards (potentially exposed to mechanical damage and animal gnawing), and then into the house.

* Apartment Buildings: From the basement or entrance equipment room, the cable is routed through vertical shafts (potentially infested with rodents) and horizontal conduits to individual apartments.

* Commercial Buildings/Campuses: After short-distance outdoor installation between different buildings, the cable is routed directly into the indoor equipment room.

* Industrial Environments: Connecting buildings within a factory complex, requiring resistance to mild chemical corrosion and physical damage.

* Areas with known rodent or insect infestations: As an upgraded protection option for standard fiber optic cables.
