Listed below is the pin-out diagram for the DB15 pin port on the
external of the SWL-1550-M module:
2.5 Operation Instructions
Start-up Procedure
1. Ensure that the proper cable connections are made, which includes the
power assembly interconnects (as shown on page 4) and the DB15
connection between the module and power supply.
2. Due to the increased temperature of the device over time, it is strongly
recommended to use the SWL in a well-ventilated area with an
adequate heat sink in contact with the SWL for proper heat dissipation.
3. After plugging in the appropriate power plug into the AC Power Socket,
flip the Main AC Switch to the On position to enable electrical power to
the unit. The AC/DC converter supply’s LED will enable.
4. Connect the Optical Output Port using the indicated connector
patchcords to the appropriate signal destination to utilize the swept
wavelength optical output signal.
5. Turn the Laser Key Switch to the On position.
6. The SWL-1550-M is now enabled, with both status LEDs enabling to
green.
7. To voltage tune the device, you can use either a DC programmable
power supply to manually adjust and sweep the wavelength (from -5 to
+45 VDC;
voltages below -5VDC may cause permanent damage to the
SWL-1550-M device, and is not covered by your warranty!
), or you can
use a function generator to sweep across this same voltage potential,
up to 2 kHz. The electrical connection should be made to the Voltage
Tuning Port, which is a 50 Ohm SMA termination.
