Thunderbolt™ 3 and Thunderbolt™ 4 solutions

UL Solutions provides Intel Corporation-approved Thunderbolt™ 3 and Thunderbolt™ 4 testing service. Thunderbolt 3 increases the speed of Thunderbolt via USB-C® up to 40 Gbps, creating a compact port that supports a fast and versatile connection to docks as well as display and data devices. Thunderbolt 3 ports also supply up to 100W of power that can increase charging speeds to devices.

Thunderbolt 4 is the next-generation connectivity solution that is capable of transferring data, outputting a display and even providing power. Thunderbolt 4 builds on the innovation of Thunderbolt 3 connectivity. Thunderbolt 4 provides a 40 Gbps connection for data and video and also provides 100W of power over a single connection. It is the most comprehensive Thunderbolt specification yet with compliance across the broadest set of industry-standard specifications – including USB4™, DisplayPort™, and PCI Express (PCIe®) – and is fully compatible with prior generations of Thunderbolt and USB products.

UL Solutions’ Thunderbolt laboratory testing covers electrical and functional testing on Thunderbolt 3 and Thunderbolt 4 hosts such as laptop and desktop computers.
