OPM MODE
OVERVIEW
TEST PROCEDURES
OPM MODE
Optical power is an absolute measurement of the amount of light intensity; i.e. “brightness”, and is one of the
most basic tests performed by an optical power meter (OPM). The Fiber OWL 7+ contains a basic OPM MODE
for this purpose.
APPLICATIONS
OPM MODE enables users to perform the following basic tests:
Transmitter power measurement
Receiver sensitivity measurement
Checking patch cables
Verification of NIST calibration levels
Basic optical loss measurement
OPM MODE is indicated at the top of the display.
Since OPM MODE is designed for basic power and loss
measurements only, data storage functions are not
available.
FUNCTION KEY OPTIONS
Several OPM-related functions are available via the yellow function
button menu located at the bottom of the display.
toggle between menu lists
change currently selected wavelength (when source is NOT set to AUTO)
set an optical reference
change measurement units between dBm (ABS) and dB (REL)
resume testing for a previously stored project
switch to SIMPLE OTDR mode (see OTDR section)
