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

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted t ....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!

ABSTRACT
We are currently witnessing a strong worldwide push toward bringing fiber closer to individual homes and businesses. The emerging FTTX access networks will move the bandwidth bottleneck from the first/last mile toward metropolitan and wide area networks, creating a need for efficient optical-switching mechanisms. In this article, we review the current trends in optical switching that help to improve the bandwidth efficiency, as well as to decrease the cost and power consumption of next-generation optical networks. Our review pr ....etc

Introduction
During the past several years , traditional analog communication systems that use traditional amplitude modulation ( AM ) , frequency modulation ( FM ) and phase modulation ( PM ) have gradually been replaced with more modern digital communication systems.
Digital communication systems offer several outstanding advantages over traditional analog systems : ease of processing , ease of multiplexing and noi ....etc

Abstract:

In this paper, analysis of CDMA network with Optical Amplifiers has been done. As the optical amplifier provides gain as well as has nonlinear characterstics, gain is expected due to signal amplification as well as operation of SOAs as limiter due to gain saturation. In this paper results have been computed for with different SOA placements in a typical star topology employing CDMA. The results show that in a star topology network employing CDMA, placement of SOAs before CDMA decoder does provide benefit due to g ....etc
