NIS has been awarded a patent for dark fiber monitoring of optic cables and hub and spoke monitoring architecture. This technology enables INTERCEPTOR to uniquely use two or more dark fibers (spare, inactive) in a multi-fiber cable to protect the entire cable against intrusion. The patent also describes a technique to protect connectivity to multiple end users with a single port or zone.

Combined, these technologies make INTERCEPTOR the most cost effective PDS alternative available. (For more information, see the INTERCEPTOR Design Guide)
