1 Light Source Description
1.1 General Description
The OEM-MOPA (Master Oscillator Power Amplifier) SLD broadband light source combines an extremely
high output power with a wide optical spectrum. This is achieved by amplifying the Master SLD source’s
emission with a spectrally-matched optical power booster.
The OEM MOPA-SLD light source features compact outline dimensions 110x31x190 mm (WxHxD) and
capability of operation in a voltage range of 9-15 VDC (1.5 A max.). The device supports pulse modulation
(ON/OFF switching) at a frequency rate up to 5 kHz. The electrical pulses are to be supplied externally from
an external pulse generator.
Due to the renewed internal electronics, the OEM-MOPA light source provides three types of the optical
power control:
•manually, by pressing the top-cover pushbutton
•remotely, by applying logic signals to the back-side Remote control port
•remotely, from a PC (or laptop) via the side-back USB virtual serial port
All OEM-MOPA light sources are supplied with the USB- and Remote-port interfaces as standard options.
Please note that the OEM-MOPA light source is intended for integration into the end-user’s equipment and is
to be considered as an optical component. For this reason, the device is NOT equipped with all required
protective measures for safety operation. Before running the instrument, please check Safety Considerations
section in this document.
Please note that the OEM-MOPA light source has unique optical characteristics. Their sensitivity to optical
feedback is NOT completely studied yet. For that reason, we strongly recommend NOT exceeding the back
reflection level of 10-3. If it is not possible to fulfill, you MUST install a fiber-optic isolator at the device’s
output.
1.2 Optical Performance
Standard models of the OEM MOPA-SLD light sources are listed in the table below. Customization of the
OEM-MOPA SLD characteristics is available upon request –please contact [email protected].
The optical design is based on PM fiber. The optical output can be a 500mm-long FC/APC terminated fiber
pigtail in a 3mm reinforced tube, or an FC/APC mating sleeve for external connection of FC/APC patch
cables.

1.5 Control LEDs
The OEM-MOPA light source is equipped with three LEDs on the front side. They are intended for visual
indication of the device current status. Refer to Table 1 for the most comprehensive explanation of the LEDs’
status. Table 1. Statuses of control LEDs
LED Name
LED State
System status
“OUTPUT” *
No light
The optical output is off.
Flickering green
The optical output is starting (soft start).
Green
The optical output is on.
Yellow
SLD current limit reached –SLD degradation; time to service.
“STATUS”
No light
No power. No active SLDs.
Flickering green
Temperature stabilization is in process.
Green
SLD temperature is stabilized at the pre-set level on all channels. The
optical output can be switched on. No errors detected.
Flickering red
The optical output and all controls are disabled once the interlock has
been actuated (correspondent terminals on the REMOTE port are
open circuited).
Interlock is only operable, if the correspondent option is computer
activated (“Configuration” area in the SUPERLUM’s companion
software –see Sec. 4.3 below).
Red
Common Error. Failure of the temperature controller.
“MODE”
No light
The unit is in manual operation. Remote control option is not activated
Green
The unit is in REMOTE port operation (manual operation is disabled)
Yellow
The unit is in computer remote operation (manual operation is
disabled). USB mode.
Flickering yellow
The unit is in computer remote operation (manual operation is
disabled). USB SERVICE mode.
* –LED reflects the status of the combined optical output, i.e. all “active” SLD channels together (that user pre-selected in the companion software, or all
channels as factorypreset). Failure of, at least, one of the channels will result in the failure status of the combined optical output.
1.6 Remote Control Features
Refer to the companion software for remote control of the OEM-MOPA light source from a PC (or laptop)
using a USB connection. The device is fitted with a USB virtual serial port located on the back side of the
device.
Short summary of the most relevant remote-control features (also those available with SUPERLUM’s
companion software) are given in Table 2. See Sec. 4.2-4.4 of this document for more information on this
subject. Table 2. Remote control features
USB (virtual COM port)
REMOTE port
- ON/OFF control of the optical output;
- Pre-selection of certain SLD-channels for ON/OFF
controlling;
- Monitoring of relevant driving parameters of SLD-
channels;
- Self-test option –remote diagnostics feature;
- Enabling/disabling the option of analog remote
controlling via the REMOTE port (does not apply to the
interlock control). Activation of this option disables a
manual ON/OFF control of the optical output from the
front device panel;
- Controlling of optical performance.
The REMOTE port is operable only if the
correspondent option has been computer activated.
- ON/OFF control of the optical output by analog
remote signals;
- Monitoring of device statuses (e.g. on/off statuses of
the optical output, service status);
- Remote interlock control: interlock is actuated when
correspondent terminals on the REMOTE port are
open circuited.
- Interlock is only operable, if the correspondent
option is activated in the computer control software.

NOTE –To enable the controls of the REMOTE port, prior activation is required via USB / Ethernet interface (with use
of SUPERLUM’s companion software). The interlock is the only control option, computer activated separately from
other controls of the REMOTE port.
Activation of REMOTE controls (except the interlock control) disables a manual ON/OFF control of the optical output
from the front device panel.
Controlling via REMOTE port (except the interlock control) is possible only if the Light Source is not computer
controlled in parallel.
Refer to Sec. 4.4 below for more details about controlling via REMOTE port.

(1) Refer to Sec. 3.1 for more details.
(2) The power supply requirements indicated in Table 4 above are critical for the correct operation of the light source and must be
strictly complied with. The power supply should ideally be capable of supplying up to 2A current, however a less powerful unit may
be used but it will limit the operating temperature range. A power supply with a maximum current of less than 1.5A cannot be used.
NOTE: For compliance with the EMC standard EN61000-4-5 it is recommended that the 12V power cable be less than 3m. When
installing the Light Source into an application where the 12 V DC power cable is over 3m Superlum advise that a ferrite of the type
"Würth 742 701-5 with 6 loops" or similar, is placed on the cable.
