Részletes leírás
Optical node OD-120 converts optical signals into RF electrical signals. It cooperates with optical transmitters of MOS-211x series ( R81720, R81720B) transmitting modulated light over single-mode optical fiber. Such optical links allow to transmit multiple channels from the headend to other locations in the city etc.
Distinguishing features
- internal diagnostic system
- GaAs push-pull technology
- microprocessor controlled AGC
- two RF outputs (one of them can be switched off)
