What happens if someone shines a laser into the fiber?

The receiver's automatic gain control (AGC) handles moderate interference. A high-power laser could saturate the receiver, unplug and reconnect.

Key features

Physical-layer security: No signal radiates from the fiber, impossible to intercept without physical tap access.

SBUS direct pass-through: Native SBUS support for direct flight controller to remote controller communication.

TTL telemetry compatible: Works with standard 3.3V/5V UART telemetry streams from autopilots.

No encryption latency: Because security is physical, there is zero processing delay for encryption/decryption.

Tamper-evident design: Any physical tap on the fiber causes measurable loss that triggers LINK LED warnings.

Product Q&A

Q:Can someone intercept my video if they tap the fiber?

Yes, physical taps exist, but our system includes a loss detection circuit, the LINK LED will flicker or turn off if tapped.

Q:Is this system approved for government or other use?

The base hardware is suitable, but always consult your security officer. Physical fiber links are preferred for classified environments.

Q:Does the system add any encryption overhead?

No. The fiber optic transmission is analog/physical. You can add your own encryption at the data source if needed.

Q:Can I use this for BVLOS (Beyond Visual Line of Sight) operations?

Yes, fiber eliminates RF control link loss risks, making it ideal for BVLOS where radio redundancy is required.

Q:Is the SBUS signal delayed by the fiber conversion?

No. The total electrical-optical-electrical conversion latency is under 100 microseconds, imperceptible to flight control.
