xii IQS-12004B
1 Introducing the IQS-12004B
DWDM Passive Component
Test System
The IQS-12004B DWDM Passive Component Test System, an automated
test solution for component manufacturers and system integrators, consists
of a series of IQS modular test and measurement instruments that are
completely integrated by an off-the-shelf software application. This
revolutionary system rapidly analyzes important parameters to help you
improve your production efficiency and decrease your product time to
market.
Characterization of multiplexers, demultiplexers, filters, and other passive
components is a critical step in ensuring the optimum performance of a
wavelength-division multiplexing (WDM) system.
DWDM Passive Component Test System 1
Introducing the IQS-12004B DWDM Passive Component Test System
Step-by-Step Approach
The system performs DWDM component characterization and measures
insertion loss, spectral uniformity, bandwidth, crosstalk, channel central
wavelength, polarization dependence and optical return loss
measurements on multiplexers, demultiplexers, filters, and other passive
devices. These parameters must be controlled and tested throughout the
entire life cycle of a component, from research and development through
to production and even deployment.
The rapidity of the test procedure is achieved by scanning a very-low-noise
tunable laser source (in this case the IQS-2600B or IQS-2600CT Tunable
Laser Source) across the DUT’s spectral band while power is measured
simultaneously on all device ports. Due to the medium coherence and
unmatched sidemode suppression of the IQS-2600B/IQS-2600CT, a
dynamic range of nearly 60 dB is easily attained.
The standard configuration includes IL and ORL measurements. Adding
the IQS-5150 PSA will enable you to perform PDL measurements.
Step-by-Step Approach
Guided by your selection parameters, the software based on Windows
2000 controls the test procedure from start to finish. This systematic
approach eliminates the possibility of data entry and reporting errors, and
avoids costly procedural mistakes. In addition, time-saving features such as
Pass/Fail testing, filter masks and a part number database simplify the job
of DWDM component characterization.
2 IQS-12004B
Introducing the IQS-12004B DWDM Passive Component Test System
Test Features and Results
Test Features and Results
Each test step may be accessed either automatically or manually.
Complete results are calculated at the end of the scan and are available
both graphically and in a data table; values outside the defined test limits
are highlighted. All data is saved to a database for archiving and future
display or printing.
Create as many port types as you require. Once defined, they will be used
to build a database of part numbers, enabling you to quickly reconfigure
parameters simply by selecting the appropriate part number. The
parameters in the port mask are used in the automatic Pass/Fail analysis.
Modularity and Flexibility
The system is built with the future in mind; the modular nature of the
hardware and the flexibility of the software make it easy for you to upgrade
or expand your test station. A single-channel system for measuring filters or
gratings can be expanded to 32, 64, or more channels by simply adding the
necessary plug-in modules. The system is also very compact: an entire
16-channel system, including PDL, will fit into a 4U (standard rackmount
units) rackmount space.
DWDM Passive Component Test System 3
Introducing the IQS-12004B DWDM Passive Component Test System
System Overview
System Overview
The IQS-12004B DWDM Passive Component Test System provides spectral

IQS-1643T
The DWDM Passive Component Test System sweeps a very-low-noise
tunable laser source across the spectral band of interest (C-band or
C+L-band). While the source is sweeping, synchronized measurements
from the Wavelength Reference Module (WRM) and the measurement
power meters are acquired into the system software. At the end of the
sweep, advanced signal processing is applied to the data, resulting in
accurate IL, PDL, and ORL data.
This configuration ensures quick testing time that is practically
independent of the number of device ports (there is a nominal data
transfer and analysis penalty per channel). Because of the low source
spontaneous emissions (SSE) of the IQS-2600B/IQS-2600CT Tunable Laser
Source, a dynamic range of 60 dB is easily attained. The wavelength
reference module ensures wavelength and loss accuracy by providing
a fast and continuous wavelength and power reference throughout the
sweep.
The numerous software features are explained later in this user guide.

6 IQS-12004B
Introducing the IQS-12004B DWDM Passive Component Test System
Tunable L aser Source
Tunable Laser Source
EXFO has modified its IQS-2600B Tunable Laser Source in order to
integrate it into the IQS-12004B DWDM Passive Component Test System. To
optimize the performance of the system, the optical attenuator which
ensures a constant power output from the tunable laser source has been
removed.
You can easily identify which tunable laser source you have. The unit
designed for the DWDM Passive Component Test System bears the
mention 2600CT, while the standalone unit bears the mention 2600B.
Every customer purchasing the IQS-12004B DWDM Passive Component
Test System for applications covering both the C- and L-bands will receive
an IQS-2600CT model. Even though the tunable laser source has been
modified, it can still be used as a standalone instrument using an IQS-500
Intelligent Test System.
However, you will notice a warning message when turning the instrument
on. This warning informs you that the automatic level control (ALC) is
disabled. Also note that the power stability and repeatability values
presented in the IQS-2600B specification sheet do not apply to the
IQS-2600CT.
Any other functionality or specification, particularly those concerning the
accuracy of the instrument and wavelength stability, will not be affected by
this design change.

Introducing the IQS-12004B DWDM Passive Component Test System
Testin g Pro c e d u r e
Testing Procedure
The IQS-12004B DWDM Passive Component Test System prompts the
operator to perform a series of steps, after which it controls the different
IQS modules to perform measurements on a device under test (DUT).
The testing procedure used by the system is outlined below.
³ You can configure different test parameters in the Setup step.
³ System calibration is performed the first time the system is used. It can
also be performed as needed. Calibration comprises three elements:
detector null measurement of power meters and the WRM,
wavelength response calibration, and return loss calibration.
³ IL/PDL and ORL reference measurements are required each time the
system is turned on and are recommended whenever there is a
significant change in environmental conditions.
³ The measurement scan(s) is performed. The insertion loss (IL)
measurement requires one scan, the IL/PDL measurement requires
four scans, and the ORL measurement requires one scan.
³ At the end of the scan(s), the results are calculated and analyzed. You
can view the results and print reports as required.

³ Customer.MDB: This database contains information about your
customers. It is managed internally by the system.
³ DUTPort.MDB: This database contains Pass/Fail information about the
devices that you want to test. It is managed internally by the system.
³ ResultsN.MDB: This database contains test results. You can create as
many files as you want. For example, it might be practical to have
different files for different customers, components, or test sessions.
Basically, the system has built-in flexibility to let you choose the best
way of saving test results.

Using GPIB or COM to Control the System
The IQS-12004B DWDM Passive Component Test System also uses scan
data files. These files are the test results data files containing the IL vs. λ,
PDL vs. λ, and ORL vs. λ data. These files are created and managed by the
DWDM Passive Component Test System. They are saved only if Save
Results Curves is selected in the System Settings window.
When you create a new database in the system, you are creating only a
new ResultsN database. The customer and DUT information that you
previously entered in the first two databases (Customer and DUTPort) will
be available for the new ResultsN database.
If you need information or details about the database structure, please
contact EXFO (see Contacting the Technical Support Group on page 223).
Using GPIB or COM to Control the System
The IQS-12004B DWDM Passive Component Test System gives you the
opportunity to develop your own applications using either SCPI commands
(GPIB control) or COM objects.
The MultiPath Testing Option allows you to develop your tailored
applications using COM objects.
In order to be able to take IL, ORL, and PDL measurements with the
standard DWDM Passive Component Test System or the MultiPath Testing
Option, there are a number of required steps and procedures to follow.
