Designed for mission-critical applications such as homeland security, military, defense and perimeter security, this fiber protection switch fits in standard rack frames, or can be converted to a standalone module. It provides an automatic, seamless switch between two redundant fibers in the event that the main fiber paths were to be compromised. Being an all-optical switch, the signal stays in the optical domain. As an all-optical element, it can switch any video, audio or data optical signal. Systems applications include perimeter security, airports, launch pad monitoring, power plant security, among others.
