1. Safety instructions
Before installing and using products, please read the following carefully. The
company shall not be responsible for any loss caused by any breach of safety.
The output of the laser and erbium-doped fiber amplifier is high-power invisible
radiation. When the device works, it must not look directly at its connecting ends, so
as to avoid burns to the eyes and skin.
The device contains precision optical devices to avoid damage caused by severe
impact. Avoid severe vibration and collision. The tail fiber is easily damaged. Please
operate carefully.
The device contains electrostatic sensitive devices. Please be careful to operate
and ensure good grounding and normal power supply.
It is best to use AC voltage stabilizer to supply power in areas with unstable grid
voltage or poor voltage waveforms.
Special attention to optical fiber connector:
before using device, please make sure that the connector of the input and output
tail fiber is kept clean, especially if the output fiber connector has dirty goods, it
is easy to burn out output tail fiber and make the output optical power become
smaller. When cleaning the optical fiber end or inserting optical jumper, please
shut down the input light first. If you use alcohol to clean the fiber end, only it is
completely dry, you can connect fiber to use.
the correct order of plugging and unplugging is: for plugging optical fiber, first
inserting the output optical fiber and then inserting the input optical fiber. For
unplugging optical fiber, first pulling out input optical fiber, and then pulling
out the output optical fiber..
this EDFA is a high precision and high stability product. In order to make the
output power have high stability, please use excellent quality optical fiber . In
principle, the optical fiber should be as short as possible, and do not allow the
optical fiber to move random.
When the EDFA is not used, if there is no active cable connector connected to the
