Description
-------------------------------------
CATV EDFA ( Optical Audio/Video Amplifier )series is a high performance optical product with famous brand
Microprocessor. High dependability, low noise, especially double pump design makes a better noise figure. And
With high performance to price ratio, it is suitable for using in large and middle-size network.
Characteristic
-------------------------------------
1. Adopt several international patents pre-distortion dealing technology to guarantee the fine non-linear index,
Good CSO, CTB and C/N.
Adopt famous brand 1550 nm DFB laser instrument guarantee low noise, high power and high dependability.
2. Can initiate the mode SBS function, offer more elastic disposition.
3. Adopt Automatic Gain Control design, make different RF input level keep about equal output performance still,
Simplify installing and operation sequence.
4. The built-in microprocessor offers fine control performance and state to show that is controlled.
5. RS485 controls the interface to control by carrying on the remote state.
6.191U high-standard framework type installation.
Performance Characteristics
---------------------------------------
1. Use low-noise pump laser of famous brand with low distortion, wide bandwidth and high output optical power.
2. Use high performance erbium-doped fiber, with high energy conversion efficiency; Advanced SMT production
Process with higher reliability is used in the internal circuitry.
3. Built-in perfect microcomputer automatic control circuit, monitor a variety of working conditions of output
Power and laser in real time, to make sure the optical output power is steady and extend the working life of the
Laser.
4. Blue VFD Display displaying the operating parameters and fault information accurately and GB Class II
Transponder monitoring the network by Ethernet are built in 19"1U High-standard Rack.
Large cast aluminium drain case and high-frequency E-Electric refrigerator which make the equipment can adapt
To field environmental temperature about from -40º C to +60º C are build in the wild-type EDFA. It is mainly used
In remote areas having no indoor room
