Turn-Off Procedure
1. It is recommended to turn off the booster stage pump current first before turning off
the key switch.
2. Turn off the main AC power switch after the key switch is set to off position.
Note:
Optical input signal should be enabled before turning on pump lasers.
3.2.5
Interlock and Loss of Signal Protection
1. When the detected input signal is less than +7 dBm, all the pump lasers will be shut
off for protection purposes. Once the automatic shut off is triggered, a start over
procedure as described above is required to re-enable the amplifier output. It is
recommended to use +10 dBm or higher input power.
2. A BNC female connector on the back panel is provided as the safety interlock. It
must be shorted in order for the pump lasers to enable. Use the provided accessory
to short this port or connect it to a compatible interlock device. If the interlock is
open during normal operation, the pump lasers will be turned off. To re-enable the
pump laser output, turn the output switch on the front panel to “OFF” position first
and start over, including re-enabling the booster amplifier switch.
3.3 Remote Control (OPTIONAL)
As an optional feature, the EYDFA unit is capable connecting to an external PC
to allow for parameter monitoring and pump level adjustments. To allow
successful enabling of the amplifier, the key switch should be turned on and the
interlock should be shorted to use the software control.
1. Using the USB port on the rear panel, connect the amplifier to a PC, directly to the
USB port with an appropriate USB to USB cable.
2. By using the Device Manager (or other similar PC device tool), the amplifier should
be recognized as COM Port device. If the amplifier does not appear as a COM Port
device, you may need to install the necessary RS232 drivers included on the software
package.
3. Once the device is recognized by the PC interface, check to see if the operating PC
has a COM port communication software installed.
