Optical Fibre Based Fence
Optical Fiber Fence systems use light rather than electricity to detect intruders. During operation, light pulses are transmitted through fiber optic cable, which is typically installed on existing perimeter fencing. These light pulses are continually monitored for any change in light pattern or optical power, as may occur when the fiber is bent or broken during an intrusion attempt.
Fiber Optic Fence systems offer many advantages over other sensing technologies:
- Immunity to electromagnetic interference (EMI) - Compared to electronic, microwave, and electric field sensors, fiber optic sensors are not subject to interference from EMI.
- Safe for all environments - Fiber optic sensing cable does not carry or conduct electricity; it is safe for use around fuels, gases and combustible materials.
- Exceptional range - Fiber optic monitoring systems operate over far greater range than electronic sensing systems.
- Low incident of nuisance alarms - Fiber optic fence systems are not subject to interference due to small animals, adverse weather, changing light conditions, EMI, and so forth.
- Cost effective - Fiber optic sensing cable is easily incorporated into all types of existing fences and walls. The cable can also be mounted on posts as a standalone system. Fiber optic sensors typically do not require electrical power in the field.
