. If necessary, should keep the equipment working in the
suitable temperature & humidity (within the restrained scope). We
recommend operating unit in a dust free environment.
3.
EDFA equipment can be powered by AC or steady DC voltage. In both of
AC & DC, AC is the main power supply.
Request of power supply:
AC input
94-245VAC, 50-60Hz
DC input
36-60VDC, (48V source recommended)
Power consumption
Maximum 50W
4.
The DC power supply of the equipment must be the SELV supply type
as stipulated in the CAN/CSA C22.2 No.950-95 standard.
5.
Unit should have good grounding with grounding resistance
＜
4Ω
.
According to common international standards, AC plugs must be tri-wire with
the middle wire being the grounding wire.
Before connecting power circuit, please use appropriate (#20AWG or more)
electric wire to connect the grounding screw on the bottom to the grounding
frame. When using DC input power supply, the equipment chassis must be
grounded following the appropriate procedures for the respective location.

Optical connectivity
1.
Clean all fiber patch cords before connecting to the EDFA unit.
Cleaning Guidelines:
Fiber Patch cord connectors
- Remove the dust cap of the fiber connectors and wipe the fiber
connector tip with a dry lint-free cloth. Check if there are scratches or
debris on the connector surface by using a microscope (ie.100x or 200x).
- If no scratch or debris are found, the connector is ready for connection.
If scratches or debris are found, repeat the fiber patch cord connector
cleaning guidelines.
Fiber Bulkhead connectors
- Compressed air may be used to clean fiber bulkhead connectors. Use
compressed air according to the following specifications (at least):
- Non-residue, inert gas for precision dust removal
- Ultra-filtered to < 0.2 microns
- Recommended for optical systems
- Using compressed air as listed above, remove the bulkhead dust
cover and hold the can of compressed air about 6 inches away from
the connector. After spraying a few short bursts into the bulkhead,
