Cleveland Electric Laboratories Advanced Technologies Group’s FiberStrike® technology leads the industry in fiber optic sensor engineering, manufacturing, and application development. Also known as an FBG sensor (Fiber Bragg Grating sensor), our fiber optic sensors can measure changes in temperature, pressure, motion, vibration, acoustics, and strain. Used in fiber optic sensor systems with a portable FBG interrogator, it is flexible, scalable, and ideal for physical security, intrusion monitoring, or structural monitoring.

The Increased Reliability of a FBG Fiber Optic Sensor

FiberStrike® discrete and distributed fiber optic sensors are passive, require no electrical power, and emit no signal. Fiber optic sensors offer increased reliability over traditional electro-mechanical sensors due to their resistance to electromagnetic and radio frequency interference, lightning, and corrosion.

FiberStrike® FBG Fiber Optic Temperature Sensor / Fiber Optic Strain Sensor / Fiber Optic Pressure Sensor

Precise strain, pressure, and temperature measurements using a fiberoptic sensor can measure changes down to the picometer range. Multiple sensor types can be combined over one fiber strand with hundreds of discrete sensors.

FiberStrike® Fiber Optic FBG Sensor Integration

FiberStrike® optical fiber sensors can be integrated externally into existing structures or embedded into new construction.

Precise gauge placement and orientation is essential for obtaining the data required for each specific monitoring application. Surface preparation, gauge installation, and egress routing are necessary to ensure successful test data under critical conditions. We apply a variety of gauge types including foil, free filament, semiconductor, and fiber optic, in a variety of configurations and sizes.

FiberStrike® FBG sensors go the distance. They can function over 25 kilometers from fiberoptic end to monitoring equipment with no booster amplifiers.

  • Chemical, corrosion, and environmental resistance – optic fibers are corrosion- resistant and are immune to electrical interference and degradation due to chemicals or environmental factors.

Fiberoptic Intrusion Detection Systems vs Discrete Fiberoptic Sensor Systems

Two of the applications where fiberoptic sensors outperform other monitoring technologies are intrusion and discrete detection. Discrete Sensor Systems and Intrusion Detection Systems can be seamlessly deployed together to maximize monitoring and protection of assets.

Discrete FBG sensors are proven effective for monitoring structural health on multiple civil structures world-wide. The sensors are extremely sensitive and can measure movements down to 10-12 m. As many as 50 sensors may be multiplexed on a single optical fiber, facilitating ease of installation, egress routing and data management. Events for hundreds of discrete sensors may be monitored with real-time reporting using a single Fiber Bragg Grating interrogator. The properties of fiber optics allow DSS to be deployed over wide areas or long distances.

Discrete Sensor Systems (DSS) is for specific location and perimeter monitoring. Sensor types include FBG strain gauges, accelerometers, bolt tension (Brainy Bolts), position, acoustic signature, access/interlock switches, air flow and fiberoptic temperature sensors.

Intrusion Detection Systems (IDS) determines the location of attempted physical intrusions in data communication conduits or trays, thereby helping ensure information security. IDS also may be directly buried, providing the capability to determine location of pedestrian and vehicle traffic intrusion events over distances of kilometers. Intrusion event location accuracy is within a few meters of the event approximately equal to fiber optic loop length 100 for a single fiber. This accuracy applies to both communication conduits and direct burial systems. Accuracy improves with the use of multiple co-located fiber loops, virtually eliminating false alarms with CEL’s embedded, advanced designs and configurations. Key features of both DSS and IDS FiberStrike® systems is the response time to an event of less than three seconds, with an average response time of 1.5 seconds.

Event alert systems and data logging are integral components of Cleveland Electric Laboratories Advanced Technologies Group’s proprietary software available in the Command and Control solution. Advanced API provides a .net event output, allowing easy integration with existing C2 or C3 systems. FiberStrike® system flexibility facilitates integrating any combination of DSS and IDS into a single head-end.
