Chapter 2 - Measuring
Loss
Loss measures the signal degradation in a fiber
optic cable.
SimpliFiber
850/1300 Source injects
a signal into the fiber cable and
SimpliFiber
Meter measures the received signal at 850nm or
1300nm.
Described in this chapter are the procedures for
measuring loss in a fiber optic cable plant using
SimpliFiber
Meter and
SimpliFiber
Source.
Three different test methods are explained; they
vary in the way the launch cables are connected
when the reference value is determined.
The Reference Value
Accurate repeatable measurements of optical
power and signal loss are fundamental for the
installation and maintenance of fiber optic
cabling.
To make an accurate measurement, you need to
know the loss of your attached launch cable and
the power being transmitted.
