DWDM Technology



Wdm technology

It was first published in 1970.and by 1978 being realized in laboratory.

This term typically described it,s WAVELENGTH

In fibre optical communication wdm is a tech.which multiplex a number of optical carrier signals on to a single optical fibre by using different wavelengths(colour).

What is wdm

Data from each tdm channel is loaded on one optical frequency(wavelength)

These wavelengths are then multiplexed onto one fi ....etc

Contemporary Communication Systems Using MATLAB

This book has been developed as a supplement to traditional core texts in Communication Systems for instructors and students who wish to make MATLAB an integral part of their study of Communication Systems topics and concepts. The books in this new series are designed to promote students' problem solving and critical thinking skills through the use of MATLAB as a virtual laboratory. A 3.5 disk containing supporting MATLAB data files is bound into the book. This bo ....etc

In the case of a larger computer system inter connected through lan, wan or internet the data/storage manipulation is a major issue. The IPCFS is a flexible filesystem that can be used for creating a larger space which is mountable as a formal filesystem like ext3/NTFS to the linux machine and can perform all the properties of a filesytem.
The IPCFS gets bigger than a normal filesystem that can be build on a hard disk, cdrom or flash memmory, IPCFS is a virtual filesystem using all the storage area allocated to it in the network. The storage a ....etc

Abstract
Most device drivers have one ulterior motive and one target to achieve - deliver the maximum using the minimum. No matter how stable or feature rich a device driver might be, if it cannot perform in terms of high throughput and low CPU utilization, it is as good as any other run of the mill driver.The objective of this topic is to use the thinking out of the box concept and expose techniques, which go beyond just good programming principles to get that extra edge which can put your next driver into the elite group of high perform ....etc

Optical coherence tomography (OCT) is an optical signal acquisition and processing method allowing extremely high-quality, micrometer-resolution, three-dimensional images from within optical scattering media (e.g., biological tissue) to be obtained. In contrast to other optical methods, OCT, an interferometric technique typically employing near-infrared light, is able to penetrate significantly deeper into the scattering medium, for example 3 deeper than its nearest competitor, Confocal microscopy. Depending on the use of high-brightness and ....etc

DWDM revolutionized data transmission technology by increasing the capacity signal of embedded fiber.

This technology responds to the growing need for efficient and capable data transmission by working with different formats, such as SONET/SDH, while increasing bandwidth.

Location :
Vidyalankar Institute of Technology (VIT) is located in central Mumbai, and can be easily reach from all parts of the city. It takes about 15 minutes to walk from Wadala station (Harbour Rly.) to the institute. Also it's not all that far from Dadar station (W.Rly. & C.Rly.). Buses can drop you very close to the college. Share taxis from Wadala west also take you to the college.There are ample of buses which ply between Dadar and Wadala, so a good option for central and western students also. However, it is surrounded by slums which ....etc

INTRODUCTION

Demodulating a signal decomposes it into a slowly varying temporal envelope and a rapidly varying cosine (or fine structure--related to the instantaneous frequency of the signal). The motivation in representing a signal by envelope and fine structure comes from our desire to understand and model ....etc
