Optical node OD-002 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
