Optical Fibre Communication. Lecture delivered by Christie Alwis 2009 faculty of Applied Science for computer science , and physics special students. University of Sabaragamuwa , Belihuloya. For more details on this lecture, please visit www.christiealwis.com. Revolutions.
a.) can talk with the use of latest Technology @ any where in the world, @ low cost.
b.) can be accepted knowledge @ anywhere in the world. (e- Assessment)
Local Area Node
Domestic Transport Network (OF,
Undersea Optical Fiber Networks
International Transport Network
Both Domestic and International Transport will be on Optical Fibers. And Switching Nodes will be on NGN.
Access Network is developed to accommodate integrated services such as Internet, IPTV, Data with Voice
Attenuations in fibre
(D * (spectral width of the optical source) *(link distance))
The basic components
– A serial bit stream in electrical form is presented to a modulator, which encodes the data appropriately for fibre transmission
C= 3* 108 m/s
The following 2 major factors plays a vital role in designing the maximum capacity of an optical fibre
Theoretical Maximum of an optical fibre cableNo of wavelengths = ( 24 * 103 Gb ) / 10 Gb = 2400 wavelengths
Only 1 core is needed
Further study of optical fibre network
