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.
