Tapping to identify fiber optic cables
Detecting Taps If you know fiber can be tapped, how do you detect it? Put in your own coupler tap at the receiver end and monitor the power in the fiber continuously. If someone puts a tap on the fiber, you will see a drop in power, if only a few tenths of a. Fiber tapping is a network tap method that extracts signal from an optical fiber without breaking the connection. the paper was classified and until it was declassified around 2005, was not discussed. However, to be effective, network visibility must satisfy two basic requirements: it must provide accurate, high-granularity information suitable for diagnostics and maintenance, and it must not alter or interfere with the operation of the system. Bend Insensitive Cable (BI Cable) is probably the easiest and cheapest way to prevent someone from tapping your fiber lines (using conventional means (the government almost certainly has other technologies to extract such data)).
