One significant threat to data on optical communication networks is fiber tapping. Once someone accesses fibers in a cable or transition/splice point, they can attenuate them by physically bending the fiber strand—and removing and capturing only a small percentage of light can mean significant data theft.
The impact on network performance is often negligible and may not disrupt data transmission, so operators may never even be aware of the crime.
Similarly, enterprises are exposed more and more to sabotage acts and intrusions in protected areas where CCTV and other traditional security settings may not be enough. In order to increment security levels in a protected area, Fiber Monitoring can be also used in perimeter intrusion applications, where security managers can easily identify intruders and exact point of the intrusion is the secured area.
