Introduction - Optex Fiber SenSys Terrain Defender TD 100 Installation Manual

1. Introduction

TD100™ is a covert buried line intrusion detection sensor. It utilizes two parallel leaky coaxial
cables to create an invisible electromagnetic field that follows the cables around corners and up
and down hills. The transmit (TX) cable creates a field that couples into the parallel receiver
(RX) cable. An intruder moving in proximity to the cables disturbs the coupled signal. Measuring
the time delay between the onset of the coded pulse transmission and the receipt of the change
due to the intruder allows the system to detect and pinpoint intruder's location.
TD100 is unique in its use of Multiple Input and Multiple Output (MIMO) Digital Signal Processor
(DSP) to detect and locate intruders using End-to-End Correlation (E2EC™), a patented Fiber
SenSys technology. When fully operational to generate an alarm, the intruder must be detected
at the same time and same location by both connected processors. The product provides high
Probability of Detection (PD) and low Nuisance Alarm Rate and False Alarm Rate (NAR/FAR)
detection with unprecedented fail-safe features.
This brief introduction to the technology provides a starting point for those who wish to install the
TD100. It introduces the product components and the way that they can be interconnected to
address various applications.
The information presented herein provides background for the more detailed and subject-
focused manuals that describe the inner workings of TD100.
