Aufnahmen der Russen, die zeigen, wie eine Glasfaser-Kellnerdrohne durch einen ukrainischen Laserlichtstrahl außer Gefecht gesetzt wird. März 2026

„footage“

Well if they use unshielded optic fiber you can definitely shine a laser on it to mess with all the data going through it

If we look at the left bottom of the screen, it goes from

link-ok
RXg (Receiver Gain) -3.3 (dB)

to

no-link
RXg (Receiver Gain) -40.0 (dB)

This means that there is such a strong light in the fiber that the automatic gain control in the receiver has dialed the gain down by a factor of almost 10000, and can no longer see the much smaller actual signal from the transmitter in the drone. Presumably this is a temporary condition which would go away if the jammer is turned off. But as long as the jammer is on, the communications are broken in both directions.

Crazy footage
