Chapter 6: The Power Meter and Light
Source
You can use the CertiFiber Pro main tester to monitor and save
measurements of optical power and loss, and you can use the
main or remote tester and as an optical power source. You can
use the main tester’s power or loss meter and its light source at
the same time.
How to Monitor Power and Loss
The power meter lets you monitor the optical power supplied by
a source such as an optical network interface card or optical test
equipment. You can do these tasks:
 Monitor minimum and maximum power levels in dBm
(decibels per milliwatt), mW (milliwatts), µW (microwatts),
or nW (nanowatts.
 Monitor power loss compared to a reference level.
 Auto CertiFiber Pro and Auto SimpliFiber Pro modes let
you monitor power and loss at two wavelengths when
you use a CertiFiber
™
Pro or SimpliFiber
®
Pro source.
 Save power and loss measurements for two wavelengths
in one record.
Figure 30 shows the equipment for meter measurements.
Notes
It is not necessary to select a Fiber Type or Test
Limit when you monitor power or loss. These tests
do not have PASS / FAIL results.
Power and loss measurements from sources that
transmit network data can change as the data
rate changes.
