1,Summary
1.1Summary
EDFA(Erbiur Doped Fiber Amplifer)is one of the most representative amplifier.Er-doped fiber is the core of EDFA,with quartz optical fiber as matrix material,And in the mixed with certain proportion of rare earth elements in erbium ions(Er3+).
Application:CATV Network
Communication network
Industrial pulse amplifier
1.2 feature
1.2.1)High Quality:Adopt international brand Pump of 980nm wavelength,Power, gain flatness and reasonable optimization by the software, minimizing EDFA NF. The system can get excellent noise index.
1.2.2)Flexibility:The module adopts the international standard size case.
1.2.3)Reliability:Internal PCB adaopts 4 layers structure,obtained in the current protection.
1.2.4)Intelligent:Built in CPU,APC&ATC control circuit,With the power supply of +5V,module can work normally
