EDFA 1550nm Optical Fiber Amplifier(20db) Cable Erbium-Doped Fiber Amplifier, Cable TV head-end equipment, with optic switch

Special note:1. Erbium-doped fiber amplifiers are optical power amplifiers. The installation and commissioning must be performed by professional technicians. Read this manual carefully before operation to avoid damage to the equipment due to incorrect operation, or to cause accidental injury to the operator.。2. When the optical fiber amplifier is working, an invisible laser beam will be emitted from the optical signal output adapter located on the rear panel. The optical signal output port should be prevented from aligning with the human body, and the optical output port should not be directly viewed with the naked eye to avoid the human body and human beings. Eyes cause permanent damage! ! !3. Any operation on the output jumper should be performed with the pump laser switched off. Do not insert or pull out the output port with optical. This will cause the jumper head to burn out and cause the output power to drop.4. When installing fiber optic connector, the force should be appropriate, otherwise the ceramic tube inside the adapter may be broken. Once the ceramic tube is fragmented, the output optical power will be greatly reduced, and the optical fiber connector will rotate slightly, and the output optical power will change significantly.5. The factory default pump opening threshold is -12dBm. When the input optical power is <-12dBm, the device has no power output.6. Before the equipment is powered on, it should be confirmed that the grounding terminals of the chassis and the power socket have been reliably grounded (the grounding resistance should be less than 4 Ω) to prevent the static electricity from damaging the laser device and prevent the chassis from being energized to harm the human body.7. In order to ensure long-term stable operation of the equipment, users are advised to configure a dedicated AC power supply for the equipment in regions where the grid voltage is unstable or where the voltage waveform is poor. Conditional users can also configure uninterruptible power supply (UPS) systems. In areas where the ambient temperature changes too much or the room environment is poor (the ideal operating ambient temperature of the equipment is 25°C), it is recommended that the user configure a dedicated air conditioning system for the equipment to improve the working environment of the equipment.
