One way to detect fiber tapping is by noting increased attenuation added at the point of tapping. Some systems can detect sudden attenuation on a fiber link and will automatically raise an alarm. [2] There are, however, tappers which allow tapping without significant added attenuation.
The bug was unusual in that it had no power source or active components, making it much harder to detect—it was a new type of device, called a passive resonant cavity bug. The cavity had a metallic diaphragm that moved in unison with sound waves from a conversation in the room.

On 25 August 2009, U.S. patent 7,580,533 was issued for a device that uses a laser beam and smoke or vapor to detect sound vibrations in free air ("Particulate Flow Detection Microphone based on a laser-photocell pair with a moving stream of smoke or vapor in the laser beam's path"). Sound pressure waves cause disturbances in the smoke that in ...
