FOX Function
The FOX function is used to make automatic, bidirectional optical power measurements
and / or ORL measurements at one or several wavelengths. This function is also used
to make a distance measurement of the link under test.
Two MTS 8000 are required, each one equipped with an OFI module at each end of the
fiber.
The OFI module 81xx is also compatible with the OFI-2000.
With the FOX function, the two MTS 8000s can communicate and send messages to
each other.
Configuration of the FOX automatic measurement
Two types of parameters can be modified in the FOX configuration of the OFI.
• The Acquisition parameters
• The results screen parameters.
