8 Cores Single Mode Aerial Outdoor Fiber Optic Cable Light-Armored for Duct and Direct Burial
The GYXTW 8b1 SM 8 Cores Aerial Light-armored Outdoor Fiber Optical Cable is a uni-tube, light-armored fiber optic cable engineered for aerial and duct applications. Its designation follows Chinese industry standards: G for outdoor, Y for center tube (uni-tube), X for jelly-filled, T for steel tape armor, and W for parallel steel wires.
- Central Loose Tube: Contains 2 to 24 optical fibers (typically G.652D single-mode or other types) protected by a high-modulus plastic tube filled with a water-resistant jelly.
- Armoring Tape: A layer of corrugated steel tape (PSP) is wrapped longitudinally around the tube to provide moisture resistance and protection against rodents and mechanical crush.
- Strength Members: Two parallel steel wires are embedded on opposite sides of the outer jacket to provide the necessary tensile strength for aerial hanging and long-distance pulls.
- Outer Sheath: A durable Polyethylene (PE) jacket that is UV-resistant and suitable for harsh outdoor environments.

| Feature | Typical Specification |
|---|---|
| Fiber Count | 2 to 24 cores |
| Installation Method | Aerial, Duct, or Direct Burial |
| Crush Resistance | High (due to corrugated steel tape) |
| Water Blocking | Jelly-filled tube + water-blocking material |
- Aerial Deployment: Suitable for suspension between poles due to its lightweight design and high tensile strength.
- Duct Installations: Compact size and smooth PE jacket make it easy to pull through underground conduits.
- Backbone & Local Networks: Widely used in telecommunications FTTH, CCTV, and campus-wide data transmission.
