1. General Information
1.1 Introduction
This manual contains information on the installation and operation of the EDFA-MP-
MSA modular erbium doped fiber amplifier (EDFA) unit.
1.2 Product Overview
The Optilab EDFA-MP-MSA EDFA Module is an ideal building block for
photonic subsystems and OEM system integration. Using an FBG stabilized,
uncooled pump LD, this low power (LP) version of the EDFA module is
designed for minimal electrical power consumption and thermal loading. Pump
laser protection and alarms are equipped to ensure the reliability and safety of
the device. The module requires only a single 5VDC power supply for operation,
with total current draws as low as 260mA in saturation output mode.
1.3 Features
•Low power consumption of less than 1.5W
•High stability
•Low noise
•Low polarization dependence
•Modular Design for OEM Integration
1.4 User Safety
1. The EDFA-MP-MSA unit emits high intensity invisible light from the optical
output receptacle. Avoid direct exposure to skin and eyes.
2. The module case is fully certified for EMS protection. The user should
never open the module case; any attempt will void the warranty and may
result in electric shock and EMS attack to equipment in the vicinity.
3. The user should avoid using any solvent or vaporizing chemical to clean the
exterior. It may result in damage to the surface and internal circuits.

Listed below is the pin-out diagram for the 30 pin port on the external of the
EDFA-MP-MSA module:
2.5 Operation Instructions
Start-up Procedure
1. Ensure that the proper cable connections are made, which includes the
cable assembly interconnects (as shown on page 4) and the 30 pin
connection between the module and power supply.
2. Plug in the After plugging in the AC/DC Power Adaptor into the appropriate
socket, the 5V VDC supply will automatically be enabled to the EDFA.
3. Ensuring the optical input signal is turned off, connect the optical signal for
amplification via the optical input port using the indicated connector
patchcords.
4. Connect the optical output port using the indicated connector patchcords to
the appropriate signal destination to utilize the amplified optical output signal.
5. After checking all physical patchcord connections, turn the input signal laser
source on.
6. The EDFA-MP-MSA is now enabled, with the gain current set to maximum
amplification for the current input signal level.

Optical Output Adjustment Procedure
To adjust the optical output level via current bias adjustment for the EDFA-MP-
MSA, please refer to the PC connection mode in sections 2.6 and 2.7 for more
information.
Patchcord Swapping Procedure
1. Through either the AC/DC Power Adaptor disconnection or the computer
interface lowering the bias current, disable the optical output of the EDFA
module.
2. Swap patchcords as desired. Only connect the indicated connector
patchcords to the optical input/output receptacles, cleaning them as
necessary.
3. Re-enable the desired output power by reversing the procedure in step one;
normal operation will resume in a few seconds.
Over-temperature Procedure
1. When the Temp Overheat warning enables the pump laser will shutdown
automatically and the system will freeze up.
2. Disconnect the AC/DC power adaptor.
3. Restart the unit using the Start-up Procedure described above.
4. To prevent temperature issues in the future, please allow for adequate
ventilation and increased heat sinks for proper dissipation of heat.

2.6 PC Connection Mode
For the standard EDFA-MP-MSA, connecting the module to an external PC will
allow for parameter monitoring and pump current adjustments. If you have an
EDFA-MP-MSA with additional software control, please refer to the additional
supplemental manual for complete information.
Using the USB port on the cable assembly, connect the EDFA module to a PC
using the following connection diagram and serial port settings:
2.7 RS232 Command Set
When the electrical connections have been made, and the software settings for
serial port transmission are set correctly, you are now able to send commands
to the EDFA module. For the basic EDFA-MP-MSA, there are two commands
available:
READ –Displays the current parameters and settings.
SETC:XXX –Sets the current for the output of the laser, in which it will adjust
from the current setting to the selected setting in a few seconds. The current
selection range is between 0 –610 mA.
NOTE: All commands are appended with a carriage return and a line feed {CR-LF}.

3. Troubleshooting
SYMPTOM
POSSIBLE CAUSE AND SOLUTION
OPTICAL OUTPUT POWER
NOT HIGH ENOUGH.
C: No optical input or optical input power too small.
S: Check optical input present or check optical input power is
correct.
C: Optical input/output connectors dirty.
S: Disable optical output and clean optical connectors.
C: Use of incorrect optical adapters or connectors.
S: Use only the indicated optical adapters and connectors. If
measurement instruments accept different connector type, then
use hybrid patchcords.
C: Optical output connector damaged.
S: Measure optical output power with power meter and compare
with readout on PC connection ‘READ’ command. Return to
Optilab for repair if the difference is high (>4 dB) and cannot be
corrected by cleaning or replacing the optical connectors. Always
apply dust cover plugs to unused optical ports to prevent the
damage of optical connectors.
C: Improper pin connections
S: If directly connecting the voltage to the 30 pin connector,
ensure that all +5 VDC pins are making adequate contact to your
supply.
EDFA MODULE IS
OVERHEATING
C: Insufficient ventilation / heat dissipation.
S: Place unit in well-ventilated area or supply additional fans for
ventilation. You may need to add a heat sink for additional heat
dissipation.
OPTICAL OUTPUT POWER
UNSTABLE.
C: Insufficient optical output isolation.
S: Connect isolator of corresponding wavelength to optical output
connector.
UNIT DOES NOT POWER
UP.
C: Improper pin connections
S: If directly connecting the voltage to the 30 pin connector,
ensure that all +5 VDC pins are making adequate contact to your
supply.
C: Insufficient electrical voltage.
S: Check that the electrical supply is at least 110 VAC.
C: AC Power cord is loose.
S: Plug power cord is firmly into the unit.

Cleaning Optical Connector End-face with Wipe and Alcohol
To properly clean optical connectors utilizing lens tissue grade wipes and alcohol
follow the procedure below. The moist wipe removes dust particles, oil and
contaminants that may damage or blot the end-face of the connector during
connection. The dry wipe removes residual alcohol that may be ignited by optical
emission.
1. Disable the optical output and turn off unit to prevent accidental exposure or
damage to the optical connector by optical emission.
2. Moisten a wipe with alcohol by placing on top of the alcohol dispenser and
push down to saturate the wipe.
3. Place the moist wipe on a work surface, and place a second dry wipe next
to it.
4. Wipe the optical connector, end-face down on the moist wipe 3 times and
then repeat on the dry wipe.
5. Visually inspect the end-face of the optical connector with an optical
microscope to verify cleanliness. Repeat steps 2 to 5 as needed.
Cleaning Optical Connector Sides, Receptacles, Adaptors with Swab and
Alcohol
Dust or particles can adhere to the insides of receptacles and adaptors or the sides of
the optical connector ferrule. Their presence can affect the alignment of the optical
fiber connectors and increase connection loss. To properly clean optical connectors,
receptacles, and adaptors utilizing a swab and alcohol follow the procedure below:
1. Disable the optical output and turn off unit to prevent accidental exposure or
damage to the optical connector by optical emission.
2. Moisten the swab by placing it on top of the alcohol dispenser and push
down to saturate the swab.
3. For receptacles, adapters, or other connection points, insert the moistened
swab and rotate the tip 1/2 turn clockwise and counter-clockwise 6 times
while applying light but firm pressure.
4. For fiber connectors, rotate the tip of the moistened swab 5 revolutions
around the connector while applying light but firm pressure.
5. Visually inspect the end face of the connector with an optical microscope to
verify cleanliness. Clean end-face as needed.
