Field Type 4 Output High Power Optical Amplifier 1535~1565nm Optical Wavelength
High Power Optical Amplifier Summary
With the implementation of Broadcast Whole-Optical-Network Transmission Fiber To The Home projects (FTTH), When EDFA is used as a Cascading Magnification Device in the CATV system, the C/N system will deteriorate seriously, So the EDFA should have High Saturation Output Power and Low Distortion, Then EYDFA(Erbium-Ytterbium-Doped Optical Amplifier) double cladding High Power Optical Amplifier can perfectly meet the demand of the nowadays FTTH and FTTB networks.
HSGF100Y-04 series Outdoor EYDFA adopt Aluminum Die-Casting Waterproof Box structure, Process of Spray or Baking Paint. 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.
