The optical receiver ARCOTEL GA8025(OR) is intended for work in hybrid fiber-coaxial networks of cable television with deep optics penetration. Mainly its FTTH and FTTB networks .The receiver  converts the optical amplitude-modulated signal into the radio-frequency (RF) wideband signal of TV range and provides further signal amplification for its distribution through the coaxial network. 



  • Optical receiver in a compact case;
  • Wide range of input levels of the optical signal;
  • Display of optical input level;
  • High output RF signal level at low input optical signal;
  • The output stage is implemented by the scheme Push-Pull;
  • Low power consumption;
  • Protection against overvoltage output.
