Optical FTTH receiver ARCOTEL GA8030(OR)

Options receiver/node:



Optical receiver GA8030(OR) is intended for work in FTTH (fiber in house) networks. The receiver performs converting of the optical amplitude-modulated signal into the radio-frequency (RF) wideband signal of TV range and following signal amplification for its distribution through the coaxial network.

Main characteristics and technical parameters:

  • high sensibility and wide range of input optical signals;
  • output hybrid PP amplifier;
  • two RF outputs (second output - 10 dB);
  • possibility of setting of preliminary AGC slope (alternate equalizer);
  • possibility of attenuation of output signal (alternate attenuator);
  • aluminium housing with finning;
  • built-in supply unit;
  • output sockets of F type;
  • optimal ratio price/quality;

Structural scheme of optical receiver GA8030;

The structural scheme  gives a conception about functional structure of a receiver, location of control points and regulating nodes. To adjust a level and slope of output signal alternate attenuator and equalizer.

Installation of the optical receiver:

Structure of a receiver allows to install it both in premises and outside in boxes protected from water penetration. It is not recommended to locate devices under impact of direct sunlight, because it can lead to breaking of allowable heating rate. Working position of a receiver is arbitrary. It is not allowed to cover a housing with any materials, which can lead to worsening of cooling during operation.
