Recently, USB-IF announced the availability of certification for USB4 80Gbps Passive Cables. USB4 40Gbps Passive Cables that have already been certified can also achieve certification through the USB-IF Qualification by Similarity (QbS) Program. For new USB Type-C Passive Cables seeking USB4 80Gbps certification, the Test Group B-8 requirements are identical to those for USB4 40Gbps certification.
Reminder: To qualify for QbS or obtain new USB4 80Gbps certification, manufacturers should update the USB Power Delivery declaration as follows:
1. Update the XID of Cert Stat VDO
2. Set Passive Cable VDO requires B2…0 to 100b (USB4 Gen4)
3. If EPR is supported, sets B6…5 to 10b (5A)
4. Set B10…9 to 11b (50V)
5. Set B17 to 1b (Cable is EPR Mode Capable)
According to USB-IF requirement, all USB-C to USB-C cables must be labeled with their speed and efficacy to pass USB-IF compliance. Authorized testing labs are required to verify that cables use the correct Logo. If the cables do not use the 60W or 240W(EPR) logo, they will fail the consistency test.
