◆ Knowledge
Introduction |
| |
|
Optical fiber
communications have
become one of the main
pillars in modern
communication fields,
with the advantages of
high capacity, low
energy consumption, high
sensitivity, strong
anti-interference and
high security.
In the experiment is
based on the basic
principle of total
reflection, students can
study the total
reflection process and
conditions of it, then
more profound understand
the principle of
transmission in the
fiber by observing the
process. |
