WARNINGS AND CAUTIONS
WARNING - HAZARDOUS ENVIRONMENTS SYMBOL
This product is not specically designed for use in hazardous environments, for example in explosive
atmospheres. If the product is to be used in hazardous environments we recommend that the user
ensures suitable protective measures are taken.
!
WARNING - DANGER OF ELECTRIC SHOCK SYMBOL
This module may contain hazardous voltages. Before removing the module from the rack remove all
supplies and disconnect user I/O signals.
Unused slots in the PXI/LXI chassis are populated with blanking plates to prevent access to user
I/O signals that may be present. Blanking panels are available to order from Pickering in a variety
of slot widths. If the product is not used in this manner for example by using an extender card then
additional care must be taken to avoid contact with exposed signals.
CAUTION - HANDLING OF ELECTROSTATIC-SENSITIVE DEVICES SYMBOL
Certain semiconductor devices used in this equipment are liable to damage due to static voltage.
Observe the following precautions when handling these devices in their unterminated state, or
sub-assemblies containing these devices:
1. Persons removing sub-assemblies from equipment using these devices must be earthed by a
wrist strap and a resistor at the point provided on the equipment.
2. Soldering irons used during the repair operations must be low voltage types with earthed tips and
isolated from the mains voltage by a double insulated transformer.
3. Outer clothing worn must be unable to generate static charges.
4. Printed Circuit Boards (PCBs) tted with these devices must be stored and transported in
anti-static bags.
CAUTION - PRODUCT DOCUMENTATION SYMBOL
Suitably qualied & trained users should ensure that the accompanying documentation is fully read
and understood before attempting to install or operate the product.
!
WARNING - RISK OF INJURY SYMBOL
This product may be specically designed to switch optical signals. Under no circumstances look
into the end of an optical output or an optical cable attached to an optical output. LASER RADIATION
CAN SERIOUSLY DAMAGE YOUR EYESIGHT.
Read and understand the safety information of the laser source connected to the optical switch.

SAFETY INSTRUCTIONS
SAFETY INSTRUCTIONS
All cleaning and servicing requires the equipment to be isolated and disconnected from the power source and user
I/O signals (refer to the Maintenance Section).
• Appropriate manual handling procedures should be followed as dictated by the weight of the individual module or
the combined weight of the modules & chassis.
• Should a fault occur with the module or chassis, immediately isolate and disconnect the incoming power to the
chassis and the user I/O signals.
• Ensure the equipment is installed, operated and maintained by trained and authorised personnel.
• Modules are not accessed to EN 60825, users should observe the safety instructions and laser
class for the 3rd party laser source.
• The module may be capable of switching optical signals from a laser device; do not stare directly
at the user I/O ports.
• For suitably equipped products in the event of an emergency press the red “emergency stop” button situated on
the front of the unit.

The 40-850A (PXI) and 42-850A (PXIe) are 4-channel MEMS
fiber optic multiplexers and the 40-852A (PXI) and 42-852A
(PXIe) are 8-channel MEMS fiber optic multiplexers. They
are available with different connector styles to suit most
applications: FC/APC (for optimal performance), FC/PC
and SC/PC for general applications and LC and MU for
high density applications.
These multiplexers use MEMS (Micro-Electro-Mechanical-
Systems) based optical switches to route the common to a
channel by redirecting the optical signal. This is achieved
using micro-mechanical mirrors driven by a highly precise
mechanism activated via an electrical control signal.
MEMS offers many advantages over traditional optical
prism technology as used in the 40-810/815/820 modules.
MEMS offers similar optical performance but with lower
price, higher packing density, faster operate time and much
longer operating life.
Pickering can construct custom optical systems to
customers precise requirements. We have a large range
of electrical switching modules which can form a complete
PXI based telecom switching solution.
Applications for these multiplexers can be found in fiber
network configuration, fiber optic component test or where
optical signal routing is required.

Other Connector Types
Pickering can manufacture fiber optic switch modules
with other connector types, please contact sales office for
further information.
Hardware Interlock
The 40/42-850A and 40/42-852A modules are
available with an optional hardware interlock.
The interlock, when activated, will return all
optical switches to their default unpowered state
(assuming the switches are fully functional) and
also provide error notification via the software
interface. The interlock feature can be daisy-
chained between additional hardware interlock
enabled modules for example to allow one signal
to disable multiple cards. For further details
please refer to the Hardware Interlock section
within the user manual.
The hardware interlock feature is not available
on 40/42-850A-4xx or 40/42-852A-4xx modules
due to the size of the LC connectors.
Note: LED indication is not available for modules
with the hardware interlock feature.
