Analog and Digital Comparison Paper Fundamentals of Networking Analog and Digital Comparison Paper T(X) & synchronous optical network (SONET) digital hierarchy There are currently two infrastructure types that are in use today. The first being Plesiochronous Digital Hierarchy (PDH)‚ which was built on the three transmission standards identified as T-carrier (North America)‚ E- carrier (Europe)‚ and J-carrier (Japan). These transmission standards are commonly referred to as (T-X) for

LED and Laser Transmitters LED Transmitter Light - emitting diode (LED) is a standard light source that carries low speed signals at short distances. LED light source is an all plastic fiber that transmits visible light. LED put out lower power and a bigger output pattern than laser light sources. LEDs have less bandwidth and are limiting to operate up to about 250Mhz or about 200Mbs. LED light sources do not contain hazardous material and last longer‚ about 10‚000 hours. Bulbs generate less heat

HISTORY OF FIBER OPTICS * In 1840‚ Daniel Colladon and Jacques Babinet demonstrated the principle of guiding light by refraction. * It was followed by a public demonstration by John Tyndal in 1852. In 1870‚ Tyndal wrote about the property of total internal reflection in his book about the nature of light. * In 1880‚ Alexander Graham Bell and Sumner Tainter invented the Photophone‚ a device capable of transmitting sound waves over beam of light. This is considered as mankind’s first attempt

Claim:Researchers should not limit their investigations to only those areas in which they expect to discover something that has an immediate‚practical application. Reason:It is impossible to predict the outcome of a line of research with any certainty. It is a very well known fact that the most pivotal discoveries of Science have been an act of serendipity.There is probably no definite way of knowing the outcome of any particular body of research‚ despite knowing
