Single isolated cable
Above diagram shows you the structure of the isolated cable. You can
see the isolated layer spiraling Aluminum foil to cover those wires.
This spiraled structure makes an isolated layer for isolating the cables
from the external noise.
Figure F-10: Double isolated cable
Double isolated cable
You can see the double isolated cable structure as figure 10. The first
isolated layer spiraling Aluminum foil covers those wires. The second
isolated layer spiraling and crossing several nude conductors cover
the first layer shielding and those wires. This spiraled structure makes
an isolated layer for isolating those external noise.
