Measurement of Two Laser Sources with a Wavemeter
If you want two laser sources to share the same measurement device (such as a
wavemeter), you can connect two laser sources to Ch1 and Ch2, which can then be
sequentially measured during a specific time frame (if you define one):

Sequential Testing of Two or Four Devices
To sequentially test two or four devices, you can use two OSICS SWT modules. A laser
source and the input of the devices-under-test are connected to the first module. The
output of the devices-under-test are connected to the second module, which sequentially
directs the signal to a unique measurement device:

Testing of an Optical Amplifier
To test an optical amplifier, you need to connect both the non-amplified and amplified
signals to a measurement device. In this setup two OSICS SWT modules are needed.
