General information
The OLP-85 offers three different measurement modes.
• Source Mode: The instrument works as a laser source.
• Powermeter Mode: The instrument works as an optical power
meter.
Instead of using the Loss test mode which restricts the
measurement to a fiber loop, two OLP-85/OLP-85P instruments
can be used for remote operation. In this Source/Powermeter
Mode one instrument (like the OLS-85) works as a laser source,
while the OLP-85/OLP-85P works as an optical power meter.
Source and powermeter are not locked in this mode.
For information on measurement adjustements on your
powermeter device see “Powermeter Operation” on page 38.
