INNOVATION OF COMMUNICATION
3000 years ago
they send the information by carry himself and took the land and sea roads
using the system of fire beacon to send the important message
18 century
Claude Schapp
build a series of giant communication tower to send the specific message to another tower in the country
using a telescope to see and send the message around the country
emerge of new technology is the telegraph
using the most effective way to send the message by the code of morse
the middle of 19 century
Cyrus Field
make the cable of telegraph across the Atlantic to connect 2 continent
Abraham Graham Bell
solve the problem of capacity that calls "multiplexing" to send the message by a different node.
realize to combine the message in the same of wire can give more effect from telegrapht
Fiber Optic
make by fiber glass
transfer the information through
radio
starting with the concept of light
The light focus on water flow which this phenomena call "total internal reflection"
Advantages
The information is committed through air and not have wires
can transfer information from one place to another place
create by Abraham
telephone
send the sound through wire (wire and electric)
photophon
using the microphone to send the message through light reflection (mirror and radiation)
create by the engineer
frequency wave
advantage
Used low frequency wave
can send the message cod to hundreds of miles
satellite
advantage
can send the waves to another continents
the satellite can't block by weather
laser
Produced a smother radiation, vibrating with refraction
advantages
Laser flicked is faster and can bring in much information
Radiation is more accurate and can focused
disadvantage
weather ( send the information of radiation laser through a glass)
glass (it is a transparent tool)
create by a doctor ( Lawrence Curtiss)
how to send the information using the light
generate long distance light
use translucent glass
original glass
without use normal glass(silica terlaksur)
3 more items...
use normal glass(silica terekur)
3 more items...
Curtiss: use fiber endoscope and split light cause:
dusty
unclean
get stuck
create vibes optic
the light can move fast and reflection is perfect
it has millions of reflections and to be a Gastroscope
coating glass part with glass not air
In 1970,fiber move it laser radiation 1(km)
In 1975, original fiber, managed to bring light 10(km)
glass from another country must join together using a microscope to make a cable for transfer the data and information
method produce fiber optic
included in genahar ,2.000 heat
melting point and start falling
narrow down
glass object (pre-form) bring to Draw Tower
fiber remains,flexible,strong,clear
In 2000, declining telecommunication stocks
began conducting fiber optic experiments on medicine.use loporoscope fiber optic and special surdical equipment
continue fiber optic speed high with surgery long distance use fiber optic and robatic
In 1970,Bell, communication by light become reality
banking
trading data
bringing internet traffic
phone cell
