Product Introduction
Nepstech1550nm16 Port 19dbm High Power Optical Fiber Amplifier EYDFA with WDM
1. Product Application:
This manual applies to fiber amplifier. It mainly describes the performance characteristics, technical parameters, installation and debugging, common troubleshooting, and other related content of the product.In order to ensure that the equipment can be successfully installed and safely operated, please read this manual carefully before installing and debugging the equipment. And the installation and debugging should be strictly according to the specified steps on the manual to avoid unnecessary damage to equipment or accident harm to the operator. Any questions, please contact with us in time.
Special Tips:
- ErYb Co-doped 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.
