1 Introducing the IQS-9100
Optical Switch
Main Features
The IQS-9100 Optical Switch provides fiber-to-fiber positioning of optical
signals for a number of optical applications. This module, which exists in
various models depending on the number of optical ports and
configuration options it has, allows you to quickly switch light from one
fiber to another.
³ This optical switch can be controlled using applications available in the
IQS Manager software
³ The applications can control one or more modules at a time and allow
for various configurations.
³ The configurations can be modified at any time and can be saved for
future use, allowing you to save time and be more efficient.
The IQS-9100 Optical Switch 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.

Basic Switching Principles
The switch ports of 1 x N optical switches are numbered on the front panel,
while the common port is identified with a "C."
These switches are bidirectional. This means that the optical signal can
either enter through the common port and be directed toward any switch
port, or enter through any switch port and then be directed toward the
common port.
The IQS-9100-02-02 (2 × 2 model) is also a bidirectional switch. The two
positions for this switch are known as inserted state and bypass state.

The IQS-9100-02-04(2 × 4 model) is also a bidirectional switch. As
illustrated in the following figure, the IQS-9100-02-04 can be set to sixthree
positions. In three of these positions, one or both input channels do not
transmit light to output ports.

Testing with Multiple Devices
Using two optical switches, a light source and a power meter, it is possible
to perform automated qualification and production testing for multiple
devices.
To perform automated qualification and production testing for
multiple devices:
1. Connect the modules and DUTs as shown below.
2. Measure the DUTs with the power meter.

Measuring Optical Switch Port Insertion Loss
The insertion loss (IL) of any switch port can be measured using a light
source, power meter, and the IQS-9100 Optical Switch.
To measure optical switch port insertion loss:
1. Connect the light source output port to the power meter detector port
using two test jumpers linked with a bulkhead connector.
2. Store the power reading obtained as a reference value in the power
meter.

3. Using the same test jumpers, connect the light source to one of the
IQS-9100 Optical Switch ports, and connect the switch common port to
the power meter detector port (the IQS-9100 Optical Switch now
replaces the bulkhead connector).
4. The IL registered on the power meter will then be the IQS-9100 Optical
Switch port IL including connectors.

Creating Customized Switch Configurations
By interconnecting two or more switch modules, customized switch
configurations can be built. For example, 1 × 2 and 1 × 16 switches can be
connected to create a 2 × 16 switch configuration. To do so, simply connect
the common ports of both switches.

General Safety Information
CAUTION
Your Optical Switch contains sensitive precision optical
components. To ensure reliable, long-term service, observe proper
handling and operating instructions. At no time should the module
be subject to shock or impact.

Optical Switch
CAUTION
Your Optical Switch contains sensitive precision optical
components. To ensure reliable, long-term service, observe proper
handling and operating instructions. At no time should the module
be subject to shock or impact.
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.

3. Position the module so that its front panel is facing you and the top and
bottom protruding edges are to your right.
4. Insert the protruding edges of the module into the grooves of the unit’s
module slot.

Inserting and Removing Test Modules
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.
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-9100 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.

CAUTION
Pulling out a module by a connector could seriously damage both
the module and connector. Always pull out a module by the
retaining screw knob.
3. Cover empty slots with the supplied protective covers.
3a. Slide the top of the protective cover into the upper grooves of the
unit.
3b. Snap the cover into place by pushing the retaining screw knob.
CAUTION
Failure to reinstall protective covers over empty slots will result in
ventilation problems.
