FEC BER Test

The FEC BER Test collects the pre-FEC and post-FEC BER data. The pre-FEC BER is the bit error rate before the FEC is applied. The post-FEC BER is the bit error rate after the FEC is applied.

Setup

  1. Test duration

Method

  1. Enable FEC on TX ports.

  2. Clear FEC counters.

  3. Measure pre-FEC BER and post-FEC BER on RX ports.

  4. Report the time-series data of the pre-FEC BER and post-FEC BER.
