This article presents a fiber-optics-based sensing network for fault detection in power systems. This scheme is considered secure and immune from interferences. A passive rugged fiber-Bragg-grating-based sensors are present a each of the monitoring locations. magnetostrictive transducers are used in the place of CT or PT for the purpose of converting the magnetically induced currents into optical signals. The temperature drift in these sensors can be easily compensated for. An increased fault current at a certain location causes a surge in th ....etc

SEMINAR REPORT ON FIBER OPTICS BASED COMPUTER NETWORK
INTRODUCTION
In recent years it has become apparent that fiber-optics are steadily replacing copper wire as an appropriate means of communication signal transmission. They span the long distances between local phone systems as well as providing the backbone for many network systems. Other system users include cable television services, university campuses, office buildings, industrial plants, and electric utility companies.

Atop each of the Trump towers in New York City, there's a new type of wireless transmitter and receiver that can send and receive data at rates of more than one gigabit per second -- fast enough to stream 90 minutes of video from one tower to the next, more than one mile apart, in less than six seconds. By comparison, the same video sent over a DSL or cable Internet connection would take almost an hour to download.

This system is dubbed 'WiFiber' by its creator, GigaBeam, a Virginia-based telecommunications startup. Although the technolo ....etc

Optical Solitons



1. INTRODUCTION

Existence of solitons in nonlinear optical fibres was first predicted by Hasegawa and Tappert in 1973 and its experimental verification came in 1980. Ever since, both experimental and the theorotical physicists have shown keen interest in this topic due to its versatile applications. Optical solitons are formed due to the balance between the group velocity dispersion and the self phase modulation in the anomalous dispersio ....etc

which modulation technique is widely used in optical fiber communication?and why?
can we use ofdm signals in optical communication?and how?

sir,
i want all study report related to optical fiber communication .
i will study those material for submitting seminar and also clear my doubt about modulation techniques in optical communication.
this field/topic is my area of interest,and i really want to study,try to implement it.
thank you!

Advanced Fiber Optics
Introduction
Fibre optics is being used to transmit television, voice, and digital data signals by light waves over flexible hair like threads of glass and plastic. It has evolved into a system of great importance and use since the 1980’s.
The advantages of fibre optics compared to coaxial cable or twisted pair cable, are endless. Millions of dollars are being spent to put light wave communication systems into operation, as a result of its performance.
