LASER WARNING

Avoid Exposure – Invisible Laser Radiation Emitted from Apertures. Do not look into the amplifier
input or output apertures and avoid skin exposure to the laser radiation from the output aperture.

Injury to the eye or skin may result.

Laser radiation is emitted from the output port when the unit is powered on, even if there is no

optical input supplied to the amplifier. Laser radiation is emitted from the output port when a light

source is connected to the input port, even if the amplifier is powered off.

Use of controls or adjustments or performance of procedures other than those specified herein may

result in hazardous radiation exposure.

The unit is supplied with a region-specific power cord. If using your own power cord, make sure it is IEC 320
compatible.

Make sure that the line voltage rating marked on the rear panel agrees with your local supply and that the
appropriate fuses are installed. Changing of the mains fuse can be done by the user (see Section 4.2, Changing
the Fuse). With the exception of the mains fuses, there are no user serviceable parts in this product.

Do not operate in wet or damp conditions. Do not obstruct the air ventilation slots in the housing!
This device can only be returned when packed into the complete original packaging, including all foam packing

inserts. If necessary, ask for a replacement package.
Mobile telephones, cellular phones, or other radio transmitters should not to be used within the range of three

meters of this unit since the electromagnetic field intensity may exceed the maximum allowed disturbance values
according to EN50082-1.

Fiber Amplifier Chapter 3: Description

Description

Thorlabs’ EDFA100S and EDFA100P are core-pumped Erbium-doped fiber amplifiers that offer high gain, low
noise, and high output power (>100 mW over most of the wavelength range). The amplifiers are offered in a
compact, turnkey benchtop package with FC/APC input and output connectors. The current of the amplifier’s pump
laser is adjustable through the instrument front panel, which allows the user to vary the output power and gain of
the amplifier. The amplifiers feature low dispersion and low nonlinearity for applications involving femtosecond
pulses.

The amplifiers include a USB connector that allows the amplifier to be enabled or disabled remotely, as well as
allowing remote control of the pump current. For added safety, there is an interlock connector located on the rear
panel that must be shorted in order for the output to be enabled. This can easily be configured to be triggered by
doors to disable the fiber amplifier in unsafe conditions. The power switch is a key-lock system to prevent accidental
or unwanted use. An enable button must be set to activate the amplifier, and a green LED indicator displays the
current state of the unit. There is a 3 second delay before the fiber amplifier turns on, and the user is warned by the
rapidly blinking LED.

The amplifiers include a universal power supply allowing operation over 100 to 240 VAC without the need for
selecting the line voltage. The fuse access is conveniently located on the rear panel.

3.1. Shipping List

Fiber Amplifier Chapter 4: Setup

Setup

CAUTION

Prior to using the EDFA systems, it is highly recommended to clean the input and output bulkheads

as well as the connector facets to be connected to the bulkheads. Failure to clean the connectors

can result in damage to the internal connectors in the EDFA as well as the connectors on fiber

patch cables connected to the EDFA.

When cleaning the connectors, ensure that the EDFA is powered off by turning off the key switch.

Never inspect optical connectors unless all light sources in your setup have been switched off.

Please refer to Section 9.2 for further instructions regarding connector cleaning.

4.1. Setting the AC Line Voltage

The fiber amplifier has been shipped configured for 100 to 240 VAC operation. There is no end user adjustment of
the line voltage for 110 or 220 VAC. The user needs to select the correct AC cord for their location.

4.2. Changing the Fuse

To change the power fuse, follow the following steps.

1. Remove the AC power cord if it is connected to the unit.

2. Locate the fuse tray directly below the AC power cord connection on the rear panel of the unit.

3. Carefully use a flat blade screwdriver to open the fuse tray.

4. Remove the existing fuse and install the appropriate 500 mA fuse. The replacement fuse must be a 5 mm
x 20 mm, 250 VAC Type T fuse (IEC 60127-2/III, low breaking capacity, slow blow).

5. Push the fuse tray back into place making sure that it snaps and seats correctly.

6. Connect the appropriate power cord into the AC receptacle and plug the unit in.

4.3. Initial Setup

1. Set the unit on a dry, level working surface.

2. Make sure the POWER key switch on the front of the unit is in the OFF position (key perpendicular to
working surface).

3. Plug the female end of the provided AC line cord into the IEC input receptacle on the rear of the unit. Plug
the male end into a properly grounded AC socket.

4. Install the interlock pin. (See page 10 for details on the interlock circuitry.)

5. Connect the input to be amplified to the input fiber receptacle using a FC/APC fiber patch cable, carefully
cleaning both the input FC bulkhead connector and the patch cable connector beforehand. Please note that
a standard single mode (SM) 1550 nm cable should be used for the EDFA100S, while a standard
polarization-maintaining (PM) 1550 nm cable should be used for the EDFA100P. Please also note that the
input power entering the amplifier should not exceed 10 dBm (10 mW).

6. Carefully clean both the output FC bulkhead connector and the connectors on both ends of a second
FC/APC patch cable (again, noting whether the cable is SM or PM).Connect one end of the cable to the
output receptacle on the unit. Connect the other end to a power meter or another measurement instrument.
The maximum output power from the amplifier – when observing the 10 dBm (10 mW) input power limit –
is 23 dBm (200 mW). Care should be taken to avoid damage to the measurement instrument connected to
the output port. Also note that when the amplifier is enabled, it generates amplified spontaneous emission
even when there is no input light entering the amplifier. This should be considered when connecting
measurement instruments to the output port of the amplifier and when inspecting the fiber connectors.

TTN118382-D02, Rev A, November 18, 2016 Page 7

Fiber Amplifier Chapter 5: Operation

5.2. Turning On the Amplifier

1. Please consult with your organization’s laser safety officer regarding proper operation of the amplifier at
your institution.

LASER WARNING

The amplifier generates amplified spontaneous emission (ASE) even without any optical input. The

power level of the ASE can be as high as 30 mW. Therefore, all laser safety measures should be

followed even if the input light to the amplifier has been disconnected or switched off. Additionally,

it should be noted that connecting a laser to the output port of the amplifier by mistake can cause

damage to the laser due to the ASE light getting coupled into the laser source.

2. Turn the POWER key switch clockwise. The LCD display will scroll “Thorlabs EDFA” across the screen,
followed by the software revision number.

3. Make sure the interlock input is short-circuited. See page 10 for detailed instructions.

4. Press and release the ENABLE switch to activate the fiber amplifier. There will be an approximately
3 second delay before the fiber amplifier powers up. During this time, the ENABLE indicator will light up
and blink rapidly.

5. Readings for the fiber amplifier pump current (in mA) and temperature (in °C) will be activated when the
unit turns on. The temperature will typically require 1 to 2 minutes to stabilize.

5.3. Viewing Information

The EDFA100S and EDFA100P use a single four-quadrant LCD to display and access information. At any time,
display variables can be adjusted by simply rotating the control knob located to the left of the display. The following
information will be available:

 Top Left – Indicates device type (EDFA).
 Top Right – Indicates the amplification band of the

device. This is set to 1550 nm for the EDFA100S and
EDFA100P fiber amplifiers.

 Bottom Left – Indicates the pump current.
 Bottom Right – Indicates the actual temperature of the pump laser, in C. The system defaults to a

temperature that is set at the factory. The temperature control is always active and may require 1 to 2
minutes to fully stabilize.

5.4. Adjusting the Fiber Amplifier Gain

The fiber amplifier gain and output power are controlled by varying the pump current. The system specifications
and the test data provided for each unit show the performance at a pump temperature of 25 °C and the maximum
pump current of 1000 mA. A typical power scaling plot, at two different input power levels of 0 dBm and -20 dBm,
is shown in Figure 2 below. This plot can be used as a reference to adjust the gain and power of the amplifier by
varying the pump current.

To adjust the pump current, press the adjustment knob once. The bottom left indicator on the LCD screen, which
shows the current in mA, will start blinking when the control knob is pressed. Adjust the control knob until the desired
current is achieved. Adjusting the knob clockwise will incrementally increase the pump diode drive current, up to
the maximum drive current of 1000 mA. Adjusting the knob counterclockwise will incrementally decrease the drive
current. On system shutdown, the current setting will be remembered.

Note: The adjustment knob utilizes an intelligent speed control. Adjusting the knob slowly will increment values in
small steps, while adjusting the knob quickly will cause larger movements. This allows both fine and coarse control.

TTN118382-D02, Rev A, November 18, 2016 Page 8

Fiber Amplifier Chapter 5: Operation

Figure 2 Output Power as a Function of Pump Current, for 0 dBm and -20 dBm Input Powers

Pressing the knob a second time after pump current adjustment has been completed will allow adjustment of the
pump laser temperature in the 20 °C to 30 °C range. Temperature adjustment is typically not needed for the
operation of the EDFA100S and EDFA100P; generally speaking, optimal performance will result when the pump
temperature is kept at the factory default of 25 °C.

Pressing the control knob again (i.e., a third time) will exit the adjustment mode and revert back to the viewing
mode, locking in the selected parameters. This can also be achieved by allowing the display to time out at any point
in the process. The display will adjust in real time to the new current setting.

5.5. Turning the Fiber Amplifier Off

 Standby Mode – By adjusting the control knob fully counterclockwise, the pump current will adjust down

to the threshold current and then to standby mode.

 Disable/Enable Mode - The amplifier output can be turned off by pressing and releasing the ENABLE

switch. The pump diode temperature will be maintained even when the amplifier is disabled.

 Power Down - When completely powering down an enabled unit, first press and release the ENABLE

switch and then turn the POWER key switch counterclockwise, which will turn OFF the entire unit. Anytime
the unit is turned OFF and then turned back ON, the fiber amplifier will be disabled until the ENABLE switch
is pressed. The pump current setting is retained when the amplifier is powered OFF.

Making Safety Interlock Connections

The EDFA100S and EDFA100P are equipped with a remote interlock connector located on the rear panel, as shown
in Figure 1 on page 7. In order to enable the fiber amplifier, a short circuit must be applied across the terminals of
the Remote Interlock connector. This connection is made available to allow the user to connect a remotely actuated
switch to the connector (i.e. an open door indicator).

The switch that is connected to this interlock must be normally open (N.O.), meaning that it has to be closed in
order for the unit to be enabled. If the switch is changed to an open state, the amplifier will automatically shut down.
If the switch returns to a closed condition, the amplifier will not re-enable until the ENABLE switch is pressed or until
the Set Enable command is entered in the command-line interface (see Section 7.3).

All units shipped from Thorlabs are configured with a shorting device installed in the interlock connector. If you are
not going to use this feature then you can leave the shorting device installed and the unit will operate normally, as
described throughout this manual. If you wish to make use of the interlock feature you will need to acquire the
appropriate mating connector (e.g., a 2.5 mm mono jack, available at most electronics stores) and wire it your
remote interlock switch.

The electrical specifications for the interlock input are shown in the following table.

Fiber Amplifier Chapter 7: Remote Communications

Remote Communications

7.1. Installing the USB Drivers

Prior to running the command line interface, the USB drivers must be installed. The EDFA100S or EDFA100P must
not be connected to the PC while installing the drivers. To install the driver, locate the USB flash drive include in
the shipment of the fiber amplifier. Run the executable file provided in the compressed folder on the flash drive.
Follow the onscreen prompts to install the driver. After the driver is installed, attach the fiber amplifier to the PC and
power it on. Your PC will then detect the new hardware and will prompt you when the installation is complete. Upon
completion of the driver installation, the amplifier is recognized as a serial (COM) port on the PC. A terminal emulator
can be used to send commands to the serial port.

7.2. Command Line Interface

Once the USB drivers have been installed, the unit connected to the PC, and the power turned on, configure the
terminal emulator as follows:

 Baud Rate = 115.2K Bits Per Second
 Data Bits = 8
 Parity = None
 Stop Bits = 1
 Flow Control = None

If the connection is correct you will see the following after pressing the “Enter” key.

Command error CMD_NOT_DEFINED

Followed immediately by the prompt:

<

The basic structure of the interface is a keyword followed by either an equals sign “=” or a question mark “?”. The

“=” or “?” will determine if the string is a command or a query. All strings (commands and queries) must be terminated

by a carriage return (CR) or pressing the ENTER key on the computer.
The command structure is as follows:

Keyword = argument (CR)

Where “keyword” defines the function and “argument” is a numerical value followed by a carriage return (CR). See
listing below.

The query structure is a follows:

Keyword? (CR)

The “keyword” defines the function and the question mark (?) indicates a query. The string is terminated with a

carriage return (CR). See listing below.
There are a few exceptions to this which are noted below, also noted are unique shortcut keys.
The prompt symbol “<” will appear on power up and after a command is accepted by the system indicating it is

ready to receive another command line.

Fiber Amplifier Chapter 9: General Maintenance

General Maintenance

Aside from the AC input fuse, there are no user serviceable parts in this product. If you suspect something has
failed in the unit, please contact Thorlabs for advice on returning the unit for evaluation.

Always clean fiber optic connectors that will be inserted into the system and install the dust cap whenever the source
is not being used. Allowing dust and dirt onto the fiber end faces will degrade coupling efficiency and possibly
damage the fiber patch cables, both inside and outside.

9.1. Cleaning

The housing can be cleaned using a soft, slightly damp cloth. Avoid using any solvents on or near the unit. Keep
the vent holes located on the bottom of the unit and on the rear panel free of dust buildup. Restricted airflow will
cause the temperature controls to operate inefficiently and, in extreme cases, loss of temperature control.

9.2. Connector Cleaning

Always clean the ferrule end of your fiber patch cables as well as the input and output FC bulkheads prior to
inserting the fiber patch cables into the FC bulkheads. Your benchtop source comes with a fiber cleaning card.
that can be used for cleaning the fiber connector on patch cables. In addition, each unit is shipped with a FBC1
Bulkhead and Connector Cleaner for cleaning the input and output bulkheads.

Figure 3 Fiber Cleaning Card

Figure 4 FBC1 Bulkhead and Connector Cleaner

TTN118382-D02, Rev A, November 18, 2016 Page 14

Fiber Amplifier Chapter 9: General Maintenance
To use the card, peel back and tear away one small blue strip. Holding the connector firmly, swipe the connector

tip across the exposed cleaning strip. The connector tip should be flush against the card surface (i.e., held at a
slight angle) for FC/APC connectors. If you need additional connector cleaners, Thorlabs offers the FCC-7020 Fiber
Cleaning Cloth Spool.

To use the FBC1 Bulkhead and Connector Cleaner, please refer to the instructions shipped with the FBC1.

Fiber Amplifier Chapter 12: Regulatory

Wheelie Bin Logo

Regulatory

As required by the WEEE (Waste Electrical and Electronic Equipment Directive) of the European Community and

the corresponding national laws, Thorlabs offers all end users in the EC the possibility to return “end of life” units

without incurring disposal charges.
This offer is valid for Thorlabs electrical and electronic equipment:

 Sold after August 13, 2005
 Marked correspondingly with the crossed out “wheelie bin” logo (see right)
 Sold to a company or institute within the EC
 Currently owned by a company or institute within the EC
 Still complete, not disassembled and not contaminated

As the WEEE directive applies to self-contained operational electrical and electronic products, this end of life take
back service does not refer to other Thorlabs products, such as:

 Pure OEM products, that means assemblies to be built into a unit by the user (e. g. OEM laser driver cards)
 Components
 Mechanics and optics
 Left over parts of units disassembled by the user (PCB’s, housings etc.).

If you wish to return a Thorlabs unit for waste recovery, please contact Thorlabs or your nearest dealer for further
information.

12.1. Waste Treatment is Your Own Responsibility

If you do not return an “end of life” unit to Thorlabs, you must hand it to a company specialized in waste recovery.

Do not dispose of the unit in a litter bin or at a public waste disposal site.

12.2. Ecological Background

It is well known that WEEE pollutes the environment by releasing toxic products during decomposition. The aim of
the European RoHS directive is to reduce the content of toxic substances in electronic products in the future.
