FPV Drone Fiber Optic System

FPV Drone Fiber Optic System

The drone fiber optic transmission system is a fiber optic communication system specifically developed for UAV applications. The system transmits analog video signals, high‑definition video signals, and TTL level signals over optical fiber, and can be expanded to include RS485, RS422, RS232 asynchronous data, bidirectional audio, telephone, and dry contact signals as required. It is suitable for long‑distance, low‑interference, high‑stability UAV communication scenarios.

Product features：Fiber optic transmission with strong immunity to electromagnetic interference；Supports video signal and data/control signal transmission；Supports PAL/NTSC video protocols；Supports CRSF, PPM, SBUS and other control protocols；Single‑fiber FC optical connector； Airborne unit is compact and lightweight, ideal for UAV mounting

Part Number：MP-FPV-5

Operating Mode Descriptions

1. Wireless Mode

Set Slide Switch 2 to Wireless. The M/L LEDs are off, and Slide Switch 1 is disabled. Connect a wireless receiver via the VTX/RX interfaces for ground‑end wireless control.

2. Wired Mode

Set Slide Switch 2 to Wired. The M LED stays on, and the L LED flashes. After inserting the corresponding interface, the L LED stays on when the protocol link is established.

3. CRSF Mode

Set Slide Switch 1 to CRSF. Use the corresponding remote‑control adapter board and connect the ground unit to the remote via an Ethernet cable. Set the remote to external module CRSF. The L LED stays on when the link is normal.

4. DSC‑PPM Trainer Mode

Set Slide Switch 1 to Trainer. Use a 3.5 mm audio cable to connect the ground unit’s DSC port to the remote’s DSC port. Turn off the remote’s internal/external RF module and set it to Slave/Jack. The L LED stays on when the link is normal.

5. SBUS Protocol Mode

When using SBUS, set Slide Switch 2 to Wireless and do not connect any other device to the RX terminal. Select SBUS protocol on the remote, insert the adapter board into the remote, and control via SBUS.

Precautions for Use

1. Clean the fiber connector end face before use.

2. Insert the extension rod before use.

3. Secure the mounting bracket before use.

4. Maintain a steady flight speed during operation; avoid rapid descent.

5. Avoid excessive bending, pulling, or squeezing of the fiber during connection.

6. Confirm all connections are correct before applying power.

7. Observe the P, F, V, and D LED indicators during operation to verify that power, fiber, video, and data connections are normal.
