Operating the Unit
Warning
To avoid the risk of injury or death, always observe the following precautions
before initializing the unit:
• Never look into the end of an optical cable connected to an optical output
device that is operating. Laser radiation is invisible, and direct exposure can
severely injure the human eye or skin.
• To prevent potential fire or shock hazard, do not expose the unit to any
source of excessive moisture.
• Do not operate the unit when its covers or panels have been removed.
• Repairs are to be carried out only by a qualified professional.
• Operating the unit in the presence of flammable gases or fumes is extremely
hazardous.
• Do not perform any operating or maintenance procedure that is not
described in the user’s manual.
• Some of the unit’s capacitors can be charged even when the unit is not
connected to the power source.
Safety Features and Compliance
The MAP EDFA Cassette, installed as part of the MAP system, complies to CE requirements,
plus UL3101-1 and CAN/CSA-C22.2 No.1010.1. It is classified per Table 2. The following
safety features are incorporated in the design of the cassette:
• Laser output ports have shutters.
• The laser(s) does not activate unless commanded by host software.
• There is a LED on the EDFA cassette front panel indicating when the laser is on.
• The EDFA cassette shuts down to a safety interlock line from the host. Once the safety
interlock is replaced, there is a 3 second delay before the laser is re-activated.
Laser Safety Labelling
The MAP EDFA Cassette is classified per Table 2. As required by the FDA standard 21 CFR
1040.10, an identification label is placed on the side of the cassette, showing the name of
manufacturer, address, and the month and year of manufacture.

Safety Interlock and Remote Interlock
The system interlock line is a hardware safety line that controls the signal output of all laser
sources within the MAP system. The interlock line connects the MAP chassis to each laser in
the system. If the interlock circuit is broken, interlock is considered activated and all laser
sources are immediately disabled removing all light at the output connectors. Upon deactivation
of the interlock line, all laser sources are enabled after a six-second delay (assuming they have
been previously enabled). Operation and control of this line is hardware-based, therefore it is
not susceptible to software failure. User of the system interlock line is performed in two ways:
Safety Interlock key found on the master local user interface must be inserted in controller
cassette (green color upward) for the interlock to be deactivated. An operator may remove the
key when leaving the MAP unsupervised to ensure that untrained or unprepared users do not
unintentionally expose themselves to dangerous levels of optical energy.
Remote Interlock is normally a closed circuit on the master remote, the interface is available to
be integrated into a user’s safety system. A typical application would be an interruption circuit
tied to a door switch that would activate the system interlock when a door is opened. Therefore
unprepared persons entering a room where a MAP system is located will not be exposed to
hazardous levels of optical energy.
NOTE: If a slave chassis is powered while no master chassis is present on the inter-chassis
bus, the interlock line will be activated.
The interlock line will deactivate all laser sources regardless of their settings, but other factors
such as current setting and laser activation have to be considered when enabling a source
output. The following truth table shows the relationship of the system interlock line, and the
source activation circuit.
Table 3: Laser Source Signal Output Truth Table

Active Inactive Yes
Caution
• Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
• Use of any cassettes with no optical energy source in conjunction with
sources must be conducted with care and recognition of the safety required
according to the classification of the source.

• Saturated output power to 20 dBm (depending on model)
• High small signal gain up to 37 dB
• Low noise figure (NF) down to 3.3 dB
• Bulkhead optical output connectors (FC/HPC, FC/APC, SC/HPC, SC/APC)
• Pump power control
• LED alarms
• Monitors
Applications
The MAP EDFA Cassette can be used for pre-amplifier, booster and high power booster
amplifier emulation, optical network compliance tests, sensors, and live network applications.

Getting Started
Checking the Shipment
1) Perform the following steps to check that the contents of the shipment are complete:
2) Wear an anti-static wrist strap, and work in an electrostatic discharge (ESD) controlled area.
3) Check that the shipment contains the following items:
• MAP EDFA Cassette User’s Manual
• The MAP EDFA cassette is packaged separate from the MAP chassis.
NOTE: Inspect the unit for structural damage that can occur during shipping.
4) If the contents are incomplete or damaged, immediately inform JDS Uniphase and, if
necessary, return the unit as outlined in the Service section.
5) Keep the packaging.
Installing the MAP EDFA Cassette
MAP allows for hot-swapping of cassettes, which means you can install or remove cassettes
either before or after power-up. The MAP controller detects the presence and determines the
type of cassette being added or removed without affecting communication with other cassettes.
Perform the following steps to install a cassette into the MAP chassis:
1. Using a screwdriver, unscrew the two screws and remove the blanking plate from the
chassis.
2. Slide the cassette into the chassis slot until it is firmly seated. MAP automatically detects
the presence of cassettes.
3. Using a screwdriver, screw in the two screws to secure the cassette.
Caution
• If you remove a cassette you must replace the blanking plate on the MAP
chassis to maintain proper airflow within the unit.
Caution
• The cassette screws must both be securely mounted to ensure proper
grounding.

Cleaning Optical Connectors
Cleaning Universal Connector Adapter (UCA) Bulkheads and Internal Optical Connector
Caution
• Be sure the unit’s UCA and internal optical connector are clean and
undamaged. Connecting an optical connector to the unit when
contaminated/dirty can cause significant damage to the unit’s optics.
• Never clean the connectors when the unit is turned on.
The following items are required for cleaning:
• Filtered compressed air or dusting gas
• Lint-free pipe cleaners or lint-free swab
• Lint-free towels
• Optical grade isopropyl alcohol or optical grade 200° ethanol (do not use rubbing
alcohol, which contains 30% water)
1. Remove the two adapter mounting screws with the No. 0 Phillips screwdriver. Removing
the adapter will expose the internal optical connector that is fastened to the base plate.
The internal connector and base plate are mounted at the factory and should not have to
be adjusted under normal operating conditions.
Figure 6: Front Panel Optical Adapter
2. Clean the internal cavity with a pipe cleaner and alcohol (a rotating motion will yield the
best results). The adapter is a critical component that can provide highly reliable mating
of optical connector, if properly maintained.
3. Gently wipe the back surface of the adapter to ensure a clear mating surface to the base
plate.
4. Using the dusting gas or compressed air, blow the base plate and ferrule.
