FIBER OPTIC

How fiber optic perimeter protection installed by Northeast Remote Surveillance and Alarm, LLC, a commercial fiber optic installer works. Coded infrared (IR) light is sent through fiber optic cables and sensors from IR transmitters is received by IR receivers. Any attempted intrusion such as cutting, climbing or walking above the sensors will be detected by an interruption in light transmission and will trigger an alarm in the Command Center that will locate and identify the intruded zone. A Laser Diode (transmitter) launches continuous wave light into a fiber optic cable. It appears at the end of the fiber optic as a speckle pattern of light and dark patches. Under steady conditions this speckle pattern is stationary. When pressure or vibration is applied close to the sensor it causes the fiber optic to deflect and redistribute the light speckle pattern. This movement or ‘twinkling' of the speckle pattern is detected by a Photo-Diode (receiver). The output is electronically processed..
