Abstract
This paper describes the end-to-end performance of single mode Fiber Optic Network (FON), implemented for Unmanned Surveillance System (USS) application for the detection and tracking of land and sea based moving targets. Optical fibers are widely in fiber optic communications which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communication. Bit Error Rate (BER) is the ultimate key index parameter in assessing the FON for transmission of digital data from one location to another location. In this paper, in addition to BER, throughput and RFC 2544 testing were also performed over the FON using dual port VeEX ethernet analyzers. Both the fiber and copper ports of ethernet analyzers were exercised for obtaining the performance metric parameters of FON. Apart from BER measurements using ethernet analyzers, Optical Time Domain Reflectometer (OTDR) has also been used for checking the optical signal loss over FON. The performance analysis of BER at different data rates and the factors affecting BER are also discussed in this paper.
I. INTRODUCTION
DRDO has been actively involved in the design and development of various types of UGVs for different applications. The first Indian tracked unmanned ground vehicle, named as MUNTRA (Mission Unmanned TRAcked) with the state-of-art technologies was designed and developed by the Combat Vehicles Research & Development Establishment (CVRDE), Avadi, Chennai.
CVRDE has developed the teleoperated MUNTRA series of tracked UGVs on the BMP II class of armoured, amphibious vehicles for specific operational missions of unmanned surveillance, NBC reconnaissance and mine detection.
