FWDM Type High Power Optical Amplifier With 32 Output 1535～1565nm
High Power Optical Amplifier Summary
High Power Optical Amplifier Indoor EYDFA adopt Whole-Aluminum Box structure, Surface with Oxidation Wiredrawing finishing process; Our Pump Source parts are manufactured by World Leading Semiconductor Company: JDSU who supply us with Multi-Mode High Power Pump Lasers, Double-Clad Synthesizers are supplied by the United States OFS company. The EYDFA device is equipped with Optical Power Output Stabilization Circuit and Laser Thermoelectric Cooler to ensure stable work. Microprocessor software do monitor the Working Status of the laser, the Working Parameters are displayed by the Digital Panel (LCD). Once the Working Parameters of the laser deviate from the Software Setting Allowable Range, Microprocessor will automatically turn off the Laser Power, Red Light flashes alert, The Digital Panel indicates the cause of the failure.
