Fiber optic security system. reflected Light Time Differential (RLTDR)
long range sensor loop utilizes a newly developed patent pending technology called Reflected Light Time Differential (RLTD) RLTD offers a unique and easily deployed intrusion detection system utilizing a single mode fiber optic cable and a single head end controller. The system is capable of protecting perimeters up to 50 kilometers in length (100 km of fiber). The system offers major cost reduction over comparable OTDR or Fiber Bragging installations.
