Fiber Optic cable is used in place of wire because it offers far superior immunity to electrical noise but it is more delicate and
requires careful handling. With fiber optics, electrical signals are converted to light with a transmitter LED. The light passes down
the fiber where it is converted back to an electrical signal at the receiver end. Any damage to the fiber from sharp bends or pulling
that stretches the fiber can reduce it’s ability to transmit light. We run the fiber inside a hose for most of its length to protect it
from abrasion, burning from hot metal or sharp bends but the ends are exposed and must be handled with care.

WARNING
Disconnect primary power at the source.
Avoid the following:
1. If you need to pull the cable through a power track do not fold the fiber back on itself making a sharp bend where it exits
the hose.
