Operation Data / Defect Indication
Noise Margin Maximum upstream and downstream noise margin.
Attenuation Maximum reduction in the strength of the upstream and downstream signal.
Fast Path FEC Correction
There are two latency paths that may be used: fast and 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
Fast Path CRC Error
The number of Fast Path Cyclic Redundancy Check errors.
Interleaved Path CRC Error
The number of Interleaved Path Cyclic Redundancy Check errors.
Loss of Signal Defect
Momentary signal discontinuities.
Fast Path HEC Error
Fast Path Header Error Concealment errors.
Interleaved Path HEC Error
