Important Note to Purchaser
All technical information and recommendations related to Thorlabs products
made in this manual are believed to be reliable. Before utilizing the product,
the user should determine the suitability of the product for its intended use.
The user assumes all risks and liability whatsoever in connection with such
use.
Warranty
The ASE-FL7002 is warranted against defects in materials and workmanship
for a period of one year from the date of shipment. During the warranty period
Thorlabs will at it’s option repair or replace products that are found to be
defective.
This warranty does not apply to defects caused by improper handling or
operation of the ASE-FL7002. If the product is found to show excessive wear
or to show signs of misuse Thorlabs will provide the customer with a
quotation on repairing or replacing the unit.
The warrantee will be void if it is found that the fiber module has been
opened; please see WARNING below.
WARNING:
There are no user serviceable parts inside of this unit.
The fiber module (4” x 8”, with black cover) located inside the box is
hermetically sealed. Removal of the cover that seals the fiber module will void
the warranty on the ASE-FL7002; replacement fiber module cost is in excess
of $14,000. Please do not attempt to service this system; call Thorlabs, Inc. at
973-579-7227 for service.
The ASE-FL7002 is a broadband white light test source in the 1510nm to
1610nm regions. It has been designed to satisfy the demand for longer
wavelength (1550nm to 1600nm) test equipment for the emerging L-band
market.
This device takes advantage of an erbium doped fluoride fiber that is pumped
with a single 1480nm laser diode to produce 20mW (13dBm) of white light.
The very broad output spectrum has been achieved by utilizing an erbium
doped fluoride fiber pumped by a single laser diode, this design allows for a
higher degree of power and wavelength stability than conventional silica
fibers. The output fiber is a standard SMF28 silica fiber.

Operation:
Power Connection
Only use a three pronged AC power cord; failure to provide an adequate
earth ground can cause severe damage to the instrument.
This instrument is equipped with a switchable power supply to accommodate
the two standard line voltages. It is pre-set at the factory for 100 – 120V. If it
is necessary to switch the input line voltage to 200 – 240V standard, the main
box can be opened and the switch accessed. Do not open the fiber module.
Please insure that your power source falls within the range specified on the
back panel.
Warm Up
After the AC line cord has been connected to your house power turn the main
switch on the front panel on. Allow the unit to warm-up for 1 hour prior to use.
Optical Connection
The standard ASE-FL7002 is supplied with a FC/PC output connector. Please
keep this output connector covered when not in use.

Do not use an index matching gel with the ASE-FL7002. Typically, the use of
an index matching gel will not improve the coupling of our standard ultrapolished FC/PC connector. The use of a gel will very often lead to
degradation of the performance of the connection in that it effectively traps
contaminants that will damage the physically contacting connectors.
Thorlabs strongly recommends that all connector ferrules be visually
inspected prior to attachment to the ASE-FL7002. Any dirt or imperfections on
the ferrule must be removed prior to connection. Making consistent
measurements with this instrument depends strongly on the quality of the
connections.
Connector Cleaning Procedure
1. Using filtered dry compressed air (Thorlabs item #VRK404) blow the end
of the connector to remove any loose contaminants.
2. Apply isopropyl alcohol to a lint free wipe (Thorlabs item #KM32) and
clean the side of the connector ferrule and the connector body.
3. Blow the connector ferrule once again with the dry filtered compressed air.
4. Apply isopropyl alcohol to a lint free wipe and clean the end face of the
connector ferrule.
5. Visually inspect the connector end face with a 100X (Thorlabs item
FF394-FC) or greater inspection scope.
6. Connect optical patch cord to ASE-FL7002.
The ASE-FL7002 is now ready for operation. Please refer to the
documentation included with these instructions for data specific to your unit.
Please contact THORLABS, Inc. for any additional technical support.
Thorlabs recommend calibration of the ASE Source every two years.
Calibration consists of a re-testing of the power and spectral stability tests.
Please contact Thorlabs at 973-579-7227 for pricing and information on
having the unit calibrated.
