Noise Margin

 

Upstream

Minimum noise margin upstream.

Downstream

Minimum noise margin downstream.

Output Power

Maximum fluctuation in the output power.

Attenuation

 

Upstream

Maximum reduction in the strength of the upstream signal.

Downstream

Maximum reduction in the strength of the downstream signal.

Fast Path FEC

There are two latency paths that may be used: fast and

Correction

interleaved. For either path a forward error correction (FEC)

 

scheme is employed to ensure higher data integrity. For

 

maximum noise immunity, an interleaver may be used to

 

supplement FEC.

Interleaved Path FEC Correction

An interleaver is basically a buffer used to introduce a delay, allowing for additional error correction techniques to handle noise. Interleaving slows the data flow and may not be optimal for real-time signals such as video transmission.
