Optical Fiber Communications


1.0 Introduction of Optical Fiber Communications

Our current age of technology is the result of many brilliant inventions and discoveries, but it is our ability to transmit information, and the media we use to do it, that is perhaps most responsible for its evolution. Progressing from the copp cable, our increasing ability to transmit more information, more quickly and over longer distances has expanded the boundaries of our technological development in all areas. ....etc

HIGH DEFINITION OPTICAL DISC TECHNOLOGY
Current Media Format
CD’s
Consist of pits and lands stamped out in a spiral pattern on the disc.
A laser then reads the pits and lands.
The change from a pit to a land or a land to a pit indicates a one while no change indicates a zero.
Current Media Format (Cont.)
CD-RW’s
Consist of a metal phase change alloy which when heated can be to change to reflectivity
CD-R’s
Consist of a dye that is applied to the disc.
When a writing laser is shined it change ....etc

ARE NATURAL FIBER COMPOSITES ENVIRONMENTALLY SUPERIOR TO GLASS FIBER REINFORCED COMPOSITES?
INTRODUCTION:-
• Natural fibers have been used to reinforce materials for
over 3,000 years.
• Many types of natural fibers have been investigated for
use in plastics .including , Flax, hemp, jute, straw,
wood fiber, rice husks,wheat,barley,oats .
• Natural fibers have the advantage that they are
renewable resources and have marketing appeal.
• Natural fibers are increasingly used in automotive a ....etc

A large interest in renewable energy systems has been developed to mitigate the green house effect. In Western Europe, the focus is thus, on wind power and especially on offshore locations, due to higher energy production, a longer expected life time and lack of suitable wind turbine sites on land. A DC cable is the preferred choice when connecting large offshore wind farms to the grid. The utilization of the Dc cables was enabled by the new HVDC transmission technology using voltage sourced converters. The offshore windfarms that are being bui ....etc
