HDO205 Receiver

The HDO205 is a dual receiver module for fibre optic return path (upstream) links in CATV networks. The excellent receiver sensitivity enables a very low optical input power like used in cable PON (RFoG) applications. The module features front panel RF test points and DC test points for optical input power. Optical input connectors can be factory installed at the rear or at the front panel.


Features at a glance:

  • Two independent return path receivers
  • Excellent noise current density
  • Wide input power/ output level range that enables very low optical input power used in cable PON (RFoG) applications
  • Three output level control modes: 1) Manual 2) Automatic based on OMI – target output level and optical input level, 3) Automatic based on optical input level
  • Small form factor family, 2 RU height
  • Fibre connectors can be located at the rear or at the front panel
