Fiber Optic Spool for FPV Drones — Fiber Optic for FPV Drones: 25 km Fiber Optic Cable Spools
The fiber optic spool from Phoenix drones is a ready-made solution for transmitting video and telemetry between a drone and a ground station over very long distances. This product from the category: Drones, EW, Drone Detectors, Components > Drone Components and Parts > Fiber Optic Spools replaces traditional VTX, ensuring transmission via light signal without radio interference.
Key Purpose and Design
The cable is wound on a light and durable spool with a printed PETG casing and a molded nylon core. At the output, the fiber optic cable is routed through a carbon tube with a milled tip for neat and safe fiber exit. The spool weighs 2.15 kg, striking a balance between mobility and reliability in flight conditions.
Advantages of Use
- Signal transmission without radio interference: fiber optics are not susceptible to interference, so the image and telemetry remain stable even in noisy areas.
- Low latency: optimal for FPV, where pilot reaction speed is crucial.
- High housing reliability: PETG and molded nylon withstand mechanical loads during transportation and installation.
- Easy integration: power and signal are connected directly via a 4-pin JST-GH type connector to the flight controller (FC).
- Large cable length reserve: approximately 25 km of winding allows for long-distance flights and link testing.
- Neat fiber optic routing: a carbon tube with a milled tip ensures convenient and durable fiber exit.
How It Works
- 1. A media converter built into the spool converts the electrical signal from the flight controller into an optical signal.
- 2. The optical signal is transmitted via single-mode fiber to the ground station.
- 3. An FC-FC patch cord provides fast and reliable connection of the spool to ground equipment.
- 4. A second media converter at the station receives the optical signal and converts it back into electrical format for video/telemetry.
