EXFO IQS-12004B DWDM Passive Component Test System for IQS-500 - Manual (Page 165)

Using the Power Meter Linearity Verification Tool
DWDM Passive Component Test System 153
Connecting the Modules for Linearity Testing
The following diagram illustrates how to link the required modules.
Connect synchronization cables (the black ones) between:
³
The IQS-9401 Wavelength Reference Module (WRM) and the power
meter to be tested.
³
The power meter to be tested and the reference power meter.
You can use standard patchcords for optical connections. However, to
ensure more stability during the verification, you may prefer to use the
supplied semi-rigid patchcord to connect the optical source output port to
the In port of the Wavelength Reference Module.
