1.3 high power optical amplifier(EYDFA)
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 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.
█ EXCELLENT QUALITY: Multi-Way 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
█ 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.
█ 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
FTTH Integrated Network Management System.
