1. General Information
1.1. Introduction
This manual contains information on the installation and operation of the
EDFA-PA-L-B benchtop erbium doped fiber amplifier (EDFA) unit.
1.2. Product Overview
The EDFA-PA-L-B is an ultra-stable high gain optical amplifier unit designed
for applications requiring high efficiency optical amplification. It is a self-
contained, benchtop unit designed to supply high and stable gain across the
L-Band range of the communications window. The EDFA-PA-L-B is
optimized for optical input power from -30 to 0 dBm.
The Optilab EDFA-PA-L-B comes in several output power levels and multiple
output ports. Please visit www.oequest.com for more details.
1.3. Features
•High saturation output power
•High gain
•High stability
•Low noise
•Low polarization dependence
•Touchscreen and remote interface
1.4. User Safety
1. The EDFA-PA-L-B unit emits high intensity invisible light from the optical output
receptacle. Avoid direct exposure to skin and eyes.
2. The equipment case is fully certified for EMS protection. The user should never
open the equipment case; any attempt will void the warranty and may result in
electric shock and EMS attack to equipment in the vicinity.
3. The user should avoid using any solvent or vaporizing chemical to clean the
equipment panel or case. It may result in damage to the surface and internal
circuits.

AC Power Socket
The AC power socket is the input for the AC power source.
A three-pin standard power cord should be used to connect
this equipment to any 110 or 220 V main supply.
MAIN ACPOWER
SWITCH
This switch enables the electrical power to the EDFA unit.
VENTILATION FANS
The ventilation fans ensure proper ventilation inside the
unit. The back panel of this equipment should be placed at
least 3 inches from the wall to dissipate heat effectively.
USB2.0 PORT
Using a standard USB cable, this port allows for remote
control and monitoring through a PC workstation.
This feature is not enabled on all units.
LAN PORT
This terminal is used allow for Ethernet connection to the
EDFA-PA-L-B for remote operation and monitoring.
This feature is not enabled on all units.
INTERLOCK
This BNC female connector is a 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, after the interlock connection
has been re-established, turn the output switch on the front
panel to “OFF” position first and start over.
