SEMINAR ON OPTICAL BURST SWITCHING (OBS)

...
ABSTRACT
Optical Burst Switching is a promising hybrid approach between coarse grain optical circuit switching and fine grain optical packet switching. burst switching (OBS) is proposed as a way to streamline both protocol and hardware in building the future generation Optical Internet. Byleveraging the attractive properties of optical communications and at the same time, taking into account its limitations, OBS combines the best of optical circuit switching and packet/c ....etc

ABSTRACT
The current fast growing internet traffic is demanding more and more network capacity everyday. As telecommunication and computer communications continue to converge, data traffic is gradually exceeding telephony traffic. This means that many of the existing connection-oriented or circuit-switched networks will need to be upgraded to support packet-switched data traffic. The concept of wavelength division multiplexing has provided us an opportunity to multiply network capacity. Current photonic switching technologie ....etc

ABSTRACT

Silicon has been the heart of the world's technology boom for nearly half a century. Each year, manufacturers bring out the next great computer chip that boosts computing power and allows our Personal Computers to do more than we imagined just a decade ago. The current technology used to make microprocessors, deep ultraviolet lithography will begin to reach its limit around 2005. At that time, chipmakers will have to look to other technologies to cram more transistors onto silicon to create ....etc

CWDM
ABSTRACT
Sending and receiving of messages from one place | U) another has always been a matter of great importance. So we should select the proper ! communication systems. Today optical fiber communication is widely used because of its advantages.
An important issue in the field of communication is the effective utilization of the capacity of a communication channel. Inorderto increase the capacity we use multiplexing techniques. WDM is a technique where modulated light from several sources of distinct wavelengths ....etc

Introducing DWDM
The following discussion provides some background on why dense wavelength division multiplexing (DWDM) is an important innovation in optical networks and what benefits it can provide. We begin with a high-level view of the segments of the global network and the economic forces driving the revolution in fiber optic networks. We then examine the differences between traditional time-division multiplexing (TDM) and wavelength division multiplexing (WDM). Finally, we explore the advantages of this new technology. ....etc

Photonic Computing is digital computing in imitation of conventional electronic computing only using laser light instead of electricity, and holograms instead of silicon computer chips. Photonic comes from photon which is the smallest unit of light just as an electron is the smallest unit of electricity. Photon comes from photo as in Kodak moment! Uninhibited light travels thousands of times faster than electrons in computer chips; therefore it is capable of computing thousands of times faster than electronic computing. Therefore, lig ....etc

ABSTRACT
Free Space Optics (FSO) or Optical Wireless, refers to the transmission of modulated visible or infrared (IR) beams through the air to obtain optical communications. Like fiber, Free Space Optics (FSO) uses lasers to transmit data, but instead of enclosing the data stream in a glass fiber, it is transmitted through the air. It is a secure, cost-effective alternative to other wireless connectivity options. This form of delivering communication has a lot of compelling advantages.
