Certification Information
Certification Information
F.C.C. Information
Electronic test equipment is exempt from Part 15 compliance (FCC) in
the United States. However, compliance verification tests are
systematically performed on most EXFO equipment.
Information
Electronic test equipment is subject to the EMC Directive in the European
Union. The EN61326 standard prescribes both emission and immunity
requirements for laboratory, measurement, and control equipment.
This unit has undergone extensive testing according to the European Union
Directive and Standards.
IMPORTANT
Use of shielded remote I/O cables, with properly grounded shields
and metal connectors, is recommended in order to reduce radio
frequency interference that may emanate from these cables.

1 Introducing the IQS-2100 Light
Source
Main Features
The IQS-2100 Light Source is designed for scientific and industrial
applications using the IQS Platforms. The IQS-2100 Light Source includes a
choice of multimode LEDs and temperature-stabilized single-mode
Fabry-Perots laser emitters, in single- and dual-wavelength configurations,
for both singlemode and multimode test applications.
ACTIVE LED
LED push button
The IQS-2100 Light Source is designed for optimal stability. Steady drive
circuitry maximizes optical output power and maintains excellent stability,
while precision optical components ensure efficient, low-loss,
narrow-beam output coupling. Laser sources are stabilized by
thermoelectric Peltier coolers that regulate submount internal
temperature.

Introducing the IQS-2100 Light Source
Available Models
A single-operation display screen lets you activate sources and select signal
wavelength, power, and modulation characteristics. The emitter’s central
wavelength is also displayed. For easy repeat access, the software stores
multiple power level and modulation configurations. Its Windows-based
software allows the IQS-2100 Light Source to integrate easily into any test
system.
The IQS-2100 Light Source supports local control (via the IQS Manager
software) and remote control (through GPIB, RS-232, or Ethernet TCP/IP
using SCPI commands or the provided LabVIEW drivers). For more
information, refer to the IQS platform user guide.
Available Models
The IQS-2100 Light Source offers different models, which are distinguished
by characteristics such as the type of LED or laser used:
³ Fabry-Perot laser
³ Surface-Emitting LED
Typical Applications
This light source is suitable for quality control, calibration, acceptance
testing, and loss and return loss testing in laboratory and manufacturing
environments.

WARNING
Do not install or terminate fibers while a light source is active.
Never look directly into a live fiber and ensure that your eyes are
protected at all times.
WARNING
Use of controls, adjustments and procedures for operation and
maintenance other than those specified herein may result in

Inserting and Removing Test Modules
CAUTION
Never insert or remove a module while the controller unit and its
expansion units are turned on. This will result in immediate and
irreparable damage to both the module and unit.
To insert a module into the controller or expansion unit:
1. Exit IQS Manager and turn off all your units.
2. Remove the protective cover from the desired unused module slot.
2a. Pull the retaining screw knob firmly towards you and release the
bottom of the cover.
2b. Gently pull the top of the protective cover downwards, to remove
it from the unit grooves.

5. Push the module all the way to the back of the slot, until the retaining
screw makes contact with the unit casing.
6. While applying slight pressure to the module, turn the retaining screw
knob (located at the bottom of the panel) clockwise until the knob is
horizontal.
This will secure the module into its “seated” position.

Inserting and Removing Test Modules
The module is correctly inserted when its front panel is flush with the front
panel of the controller or expansion unit.
When you turn on the controller unit, the startup sequence will
automatically detect your module.
Note: You can insert IQ modules into your controller or expansion unit; the
IQS Manager software will recognize them. However, the IQS-2100 locking
mechanism (retaining screw) will not work for IQ modules.
To remove a module from your controller or expansion unit:
1. While pulling gently on the knob, turn it counterclockwise until it stops.
The module will slowly be released from the slot.

4 Setting Up Your Light Source
Light source features are controlled with the Windows-compatible IQS
Manager software. Please refer to the IQS Platforms user guides for
information regarding the IQS-500/600 Controller Units and IQS Manager
software conventions.
The source is controlled and operated from within the Control Center.
Depending on your source model, some or all of the following operations
are available:
³ selecting wavelength (for dual-wavelength modules only)
³ setting attenuation
³ selecting modulation
³ saving and recalling a configuration
Note: You do not need to turn on the IQS-2100 Light Source or connect it to a DUT
to set it up. To turn on the source, see Operating Your Light Source on
page 25.

Selecting a Wavelength
Selecting a Wavelength
If you are using a dual-wavelength module, you can select a wavelength to
perform your tests. When the source is activated, the wavelength appears
in the top right corner.

Setting Up Your Light Source
Selecting a Wavelength
To select the desired wavelength:
Click the appropriate button in the Wavelength panel. A green light
identifies the selected wavelength.
To indicate a successful wavelength selection, the message Stabilization
in progress... appears on the data display (only if the source is an active
laser).
You can also select a wavelength from the QuickTools utility. For details,
see Monitoring Light Source Modules on page 29.
Note: The wavelengths specified in the Wav e l ength panel are the measured
wavelengths of the optical sources (to the nearest 1 nm for FP lasers, and
to the nearest 10 nm for LED sources).
