  • Page 91: Lane Bert

    6.0 Lane BERT The Lane BERT test is used for validating the physical interface of the optical module (QSFP28-DD, QSFP28, QSFP+, OSFP). It helps verify the performance and integrity of the optical module by checking bit error and BER per optical lane frequency offset measurement per lane.

    Aggregate and per optical lane BER and bit error count are measured, as well as pattern loss in seconds. Go back to top Go back to TOC 6.1.2 Lane BERT Signal Signal (Page 1-2) The Signal tab (fiber ports only) displays the receiving (RX) and transmitting (TX) optical level measured by the QSFP28, QSFP-DD, QSFP+ or OSFP transceiver.
  • Page 93 The received signal frequency and offset is measured and preformed on the optical interface. Current: Indicates the frequency of the input signal. Offset: Indicates the difference between the standard rate and the rate of the input signal. Min (ppm): Indicates the difference between the standard rate and the minimum deviation detected in the input signal. Max (ppm): Indicates the difference between the standard rate and the maximum deviation detected in the input signal.
