The included accessories
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)
