1.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 Fiber Amplifier) double cladding High Power Optical Amplifier can perfectly meet the demand of the nowadays FTTH and FTTB networks.
    HSGF100Y series Outdoor EYDFA adopt Aluminum Die-Casting Waterproof Box structure, Process of Spray or Baking Paint.    YGF15NN-XX(C) series 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.




2. Features
✓ EXCELLENT QUALITY: Multi-Mode High Power Pump Laser, Power is through Optimization & Balance Technology, Minimize the Noise Factor of EYDFA & comparable with general EDFA, which can make the system excellent CNR;
✓ MULTI-OUTPUTS: The Maximum Synthetic Output Power is up to 1.6W ~ 6W, Multi-Ports Output can be matched according to the user demand. Outdoor EYDFA structure size are 4×20~23, 8×18~23dBm; Indoor EYDFA structure size are 4×20~23, 8×18~23, 16×18~23, 32×18~23dBm;
✓ HIGH RELIABILITY: Outdoor EYDFA use a Fully Sealed Waterproof Box, Built-in High Performance Anti Lightning Switch Power Supply, It can be working well under AC165 ~ 265V City Electricity or AC35 ~ 80V Feed. Indoor EYDFA use a Whole-Aluminum 19" Standard Box, can be directly mounted on the 19" Cabinet.
✓ WORKING CONDITION INTUITION: The Pump Laser is the most valuable device in the whole machine.
A Microprocessor is set up to monitor the Working State of the Pump Laser, and the Working Parameters are displayed by the LCD Panel.
✓ NETWORK MANAGEMENT SYSTEM: Supporting SNMP Network Management Protocol, Telnet, HUANSHUN's FTTH Integrated Network Management System.
✓ FWDM INTEGRATED MODULE: Any model of Indoor EYDFA can be integrated with FWDM, Outdoor EYDFA 4&8 output can also be integrated with FWDM. When combined with GPON, EPON PON signals, One-Fiber-Optic Three-Waves transmission appears more simple and convenient for optical network.
