AI Technical Summary
How to test the data transmission reliability of communication devices with internal code FEC function, especially when the Ethernet interface supports cascaded forward error correction (FEC), and ensure the accuracy and reliability of the test.
By generating pseudo-random bit sequences or short-stressed random sequences as test data, FEC internal code encoding and modulation are performed on them. After receiving and demodulating the data, FEC internal code decoding is performed to determine the reliability of data transmission. Symbol boundary locking is performed when necessary to ensure the accuracy of the test results.
It enables accurate testing of data transmission reliability of communication devices with internal code FEC function, ensuring the accuracy and reliability of test results, and is applicable to different types of communication devices and media environments.
