HDO206 Receiver

The HDO206 is a dual receiver module for fibre optic return path links in CATV and FTTLA networks. 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.

The receiver has an extended frequency range to fulfil DOCSIS 3.1 requirements. HDO206 has an integrated alarm receiver to enable reception of monitoring data from AC800 FTTLA node, AC810 node, CXE880 node or E62 transponder installed into E8 node or E3 amplifier.

Features at a glance:

  • DOCSIS 3.1 compatible
  • Low noise current density
  • Two independent return path receivers
  • Also high input power model available
  • Integrated node alarm receiver (AC800 FTTLA, AC810, CXE880 or E62 counterpart)
  • Monitoring of 32 nodes
  • Wide input power/output level range
  • Three output level control modes: 1) Automatic based on OMI; target output level and optical input level, 2) Automatic based on optical input level and 3) Manual
  • Small form factor family, 2 RU height
  • Fibre connectors can be located at the rear or at the front panel
