SANTA CLARA, Calif., September 15, 2020 – Granite River Labs (GRL), a global leader in engineering services and test solutions for connectivity and charging, today announced that it has been approved by USB Implementers Forum (USB-IF) to perform official USB4™ Cable and USB4™ E-marker Silicon certification tests.

Although there is no USB Type-C® connector certified for USB4™, USB-IF has opened the USB4™ Passive Cable testing for official certification in order to make the USB4™ ecosystem complete. During the certification process, if your USB4™ Cable can pass the listed test items and a  Certified Connector Waiver Letter is provided, it may be sent to USB-IF for certification. Note all USB4™ Cables  need to use an approved USB4™ E-marker Silicon.
