ON-8604DM Four way AGC Field Optical Node

Summary

ON-8604DM is two way model. Full GaAs MMIC amplification is used as forestage, and GaAs module amplifier is used as backward stage. It meets extremely high performance index, because of optimized circuit design and design experience got by ourselves for over ten years. The fixed film threading is used for RF amplification and equilibrium to make engineering debug de more convenient. It is the best choice for CATV network.

 Performance Characteristic

1. There is 3rd level luminescent tube optical power indication in the PIN photoelectric translating tube with high responsivity. So that the optical power indication is clear.
2. Line optimal design, forestage SMT production process and backward stage module amplification is used. GaAs power-double output has high gain, low distortion and small heat dissipating capacity. RF linear is better.
3. The fixed film threading is used for RF attenuation and equilibrium of MF and DM. Equilibrium quantity will be changed if attenuation insert is plugged in the place of EQ. So it is easy to debug.
4. Output level is unchanged and CTB, CSO, is essentially the same when optical power input is changed（－7～＋3dBm）.
