8.3 Power Measurements
Clean the fiber before connecting it to the device.
The OPM is an InGaAs detector with a wavelength range from 800 to 1700nm. The displayed
power readings can be absolute (dBm and watts) or relative (dB). To measure the optical power
in a fiber, insert the test fiber on the OPM test port and press
|MODE|
until the
PM1
or
PM2
test
mode appears at the upper left corner of the display (see below an example of PM1
measurement result).
