Knowledge of smooth end chance - fiber-optic advantage
From;    Author:Stand originally
The transmission bands with fiber-optic 1. is very wide. Theory can amount to hertz of 3 billion million.

2. does not have relay end length. A few to 100 much kilometers, copper cash has hundreds of meters only.

3. does not suffer electromagnetism field and electromagnetism radiant effect.

4. weight is light, volume is minor.

5. fiber-optic communication is not electrified, use safe and usable Yu Yi to light, easy cruel place.

Range of temperature of 6. use environment is wide.

7. chemistry is corroded, service life is long.
