Aurora Digital Return Receiver

The highly efficient Harmonic RDR 4002 return digital receiver uses state-of-the-art technology to increase system reliability and enables operators to expand network services. The use of Harmonic’s digital return path solution in a network offers advantages including:

• High package density (ten RDR 4002 units in a three rack-unit platform provide 40 return data streams)

• Outstanding performance over long links, since the performance of a digital return transmission system

• is independent of link loss over the operating range of the receiver

• Increased system reliability and reduced operational

• costs as a result of greater network segmentation

The RDR 4002 works in conjunction with Harmonic’s NDT series return digital transmitters. It  mounts  in  the  HLP  4200  chassis  and  takes two optical data streams at up to 3.1 Gbps. Each input is demultiplexed into its two component data  streams,  resulting  in  four  independent  data streams received per module. These are converted back to analog waveforms by four digital-to-analog (D/A) converters
