Some of the first videos I've seen of this tech coming out to counter fiber systems. Description follows - “Ukrainian laser technology being used against a fiber-optic cable has been captured.In the video, a Russian FPV drone operating via a fiber-optic cable and waiting in ambush recorded the moment when a Ukrainian laser damages the control cable. As a result, the drone lost connection with its operator.Fiber-optic FPV drones have become a new challenge on the battlefield because they are controlled through a cable and are largely unaffected by electronic warfare systems.For this reason, alternative countermeasures are being explored, including the use of laser technologies capable of damaging or cutting fiber-optic control lines.Due to the camera’s sensor effect, the laser appears as a glowing sphere in the footage, although in reality it is a narrow high-energy beam.”Would love to have an open discussion on what we believe we are seeing here 🏴
