Introducing the CT440
2
CT440
Product Features
On CT440 with PDL option, the CT440 uses a multiple sweep Mueller method to calculate
the transfer function (TF) and the polarization dependent loss (PDL) of the device under
test (DUT). The technique relies on collecting spectral data for each of either 4 or 6
polarization state conditions (one sweep by state), before calculating both TF and PDL.
One to four optical detectors enable the CT440 to provide the direct TF and PDL (if
available) of the DUT.
The electrical input detector
Analog In
BNC port can also make these measurements, and
the synchronization signal coming out of the
Trigger Out
BNC port allows TF measurement
on remote detectors (not PDL).
The CT440 is provided with a control software (GUI) that you can install on a computer.
Earlier versions of CT440
EXFO has modified the external design of the CT440. The following figure displays the
previous models of CT440 and CT440-PDL.
If you have a previous model of the CT440 or CT440-PDL, you can still download the last
version of the GUI software and library, which are fully compatible with all hardware
versions of CT440.
You can use the instructions related to the use of the CT440 GUI and CT440 library given in
the present
CT440 User Guide
; they apply to the last version of the software whatever the
CT440 hardware version.
