HDO204接收机
The HDO204 is a quadruple receiver module for fibre optic return path links in CATV networks. The module features front panel RF test point and optical input connectors can be factory installed at the rear or at the front panel.
Features at a glance:
- Four return path receivers in one module
- Wide input power/ output level range
- Three output level control modes: Manual, Automatic based on OMI, target output level & optical input level and Automatic based on optical input level
- Integrated A/B route backup switches as a standard feature
- Automatic power save mode
- Small form factor family, 2 RU height
- Fibre connectors can be located at the rear or at the front panel
