2.5.1. Cable Performance Optimization Methodology

Go to Cable Performance Optimization Methodology User Documentation

In high-speed networking, signal integrity is everything. Whether it’s 100G, 400G, or 800G links, ensuring a low bit error rate (BER) is key to maintaining stable, high-performance data transmission. Two critical tuning parameters—RX Output Equalization and TX Input Equalization—play a major role in making sure transceivers and hosts work together smoothly. However, manually adjusting these settings is time-consuming and inconsistent, especially as data rates increase.

This test suite provides an automated optimization framework that uses PRBS-based BER testing to dial in RX Output Equalization and TX Input Equalization for the best possible signal integrity, aligning with IEEE 802.3ck and CMIS standards.
