Special Tips:
■ Er Yb Codoped Fiber Amplifier is high end professional equipment, and its installation and debugging must be operated by special technician. Read this manual carefully before operating to avoid damage to equipment caused by fault operation or accident harm to the operator.
■ While the fiber amplifier is working, there is an invisible laser beam from the optical output adapter on the front panel. Avoiding permanent harm to the body and eye, the optical output should not aim at the human body and human should not look directly at the optical output with the naked eye!
■ Please make sure that the ground terminal of the case and power outlet has been reliably grounding before turning on the power (Grounding resistance should be ＜4Ω) to prevent the static damage the pump laser device and harm to human because of case charged.
■ To ensure the equipment can work stable over a long time, in voltage unsteady or poor voltage wave region, it´s recommend to the customer that he equips special AC regulated power supply, or even AC uninterrupted power supply (UPS) system for conditional users. In the region with large temperature variation environment (The equipment's ideal work environment temperature is 25°C) or bad room environment, it´s recommend to the customer that he equips special air-condition system to improve the work environment.

4.2 Model and Power Comparison Table
Remarks:：Double power with SNMP webmaster.
1) Power indicator: One switching power supply is working – yellow; two switching power supplies are working – green.
2) Optical input power indicator：This light turns on when the optical input power is > -10dBm.
3) Pump working status indicator: Red light means the pump is not working, but the machine parameters are normal; flashing red light means the machine has broken down, related fault reason see the alarm menu of the display menu; green light means the pump is working normal.
4) Optical output power indicator: This light turns on when the optical output power is > +10dBm.
5) 160×32 dot-matrix LCD screen: used to display all the parameters of the machine.
6) Display the exit or cancel key of the setup menu.
7) Display the up or increase key of the setup menu.
8) Display the down or decrease key of the setup menu.
9) Display the enter key of the setup menu.
10) Optical signal output: This interface is the optical signal output port of the device. The default connector type is SC/APC; the port number is 4-32 optional. Other specification requirements are specified by the customer.
Warning: There is an invisible laser beam from this port while working normal. So the port should not be aligned to the human body or the naked eye to avoid accidental injury.
11) Optical signal input: The default connector type is SC/APC. Other specification requirements are specified by the customer.
12) Pump laser switching key: used to control the working status of pump laser. “ON” means the pump laser is open and “OFF” means the pump laser is closed. Ensure the key is on “OFF” position before power on. After passing self-test, rotate the key to “ON” position according to the displayed message.
1) Fan outlet.
2) RS232 interface: Used for configuring the network management parameters.
3) LAN interface: correspond to IEEE802.3 10Base-T, used for network management.
4) The AC 220V input port of power supply 1.
5) The fuse of power supply 1.
6) The switch of power supply 1.
7) The AC 220V input port of power supply 2.
8) The fuse of power supply 2.
9) The switch of power supply 2.
10) Ground stud of the chassis: used for the connection of device and ground wire.
