FiberStrike FBG Switch

A state-of-the-art solution for monitoring the status of virtually any access point. With the scalable distances allowed by fiber optics, our interlock switches can be networked across a wide area, while utilizing existing standard communication fiber networks. Additional advantages include the passive nature of each sensor, with no need for electrical power at any sensor location, immunity to environmental problems that can plague electrically-based sensors, and the ability to network virtually any number of sensors over nonconductive optical fiber into a single monitoring system that can be tens of kilometers distant from the sensing location.

FiberStrike LCM-620 switches are designed for intrusion detection at access portals such as manholes and hatchways. These switches also are well suited for high EMI/RFI industrial environments requiring many open-close sensing points, or any other applications where knowledge of many go/no-go contact states in a network is required.
