# get
<module-index>/<port-index> PP_RXFECSTATS ?

Description

Provides statistics on how many FEC codewords have been seen with a given number of symbol errors.

Actions

get

Parameters

  1. stats_type: long integer, stats type (currently always 0).

  2. data_count: long integer, the length of correction_stats + 1. Since correction_stats has a length of n+2, the value of data_count is n+3

  3. correction_stats: long integer list, array of length data_count-1. The array shows how many FEC codewords have been seen with [0, 1, 2, 3....n, >n] symbol errors, where n is the uncorrectable error threshold, the point at which the error correction fails to recover because the symbol errors are too numerous.

Important

  • FEC codewords with <=n symbol errors are correctable.

  • FEC codewords with >n symbol errors are uncorrectable.

  1. sum_of_zero_and_correctable_fec_codewords: long integer, the sum of FEC codewords with <=n symbol errors.
