Thunderbolt™ Certification Program
The Thunderbolt™ Certification Program aims to assist manufacturers in the design and development of devices that comply with Thunderbolt™ 5 specifications. We provide compliance tests, performance tests, and other validations to ensure that Thunderbolt™ products create an exceptional user experience through high-speed transmission (up to 80 Gbps / 120 Gbps) and OS interoperability across Windows, ChromeOS, and macOS.
Prior to the actual certification test, Allion assists customers in performing pre-test services to provide a clear understanding of how a product measures against the official certification test. Using the same test environment and procedures as the actual certification, our Thunderbolt™ technical consultants discover errors, identify root causes, and propose solutions. We also facilitate the submission of certification applications to Intel’s Thunderbolt web-cert portal.
In addition to standard certification tests, Allion provides comprehensive interoperability test services for Thunderbolt™ devices, ensuring your product is fully compatible with the broad ecosystem of Thunderbolt™ 3, 4, and 5 devices — including cables, docks, storage devices, eGPUs, and monitors.
Thunderbolt™ 5 Certification
Allion is authorized by Intel as one of the first test labs to provide certification testing for Thunderbolt™ products (Host). Intel officially announced Thunderbolt™ 5, the 5th generation of Thunderbolt™ technology, delivering up to 80 Gbps bandwidth (and up to 120 Gbps for bandwidth-intensive scenarios such as high-resolution displays). Allion has been an Intel-authorized Thunderbolt Authorized Test Center (ATC) since Thunderbolt 4, and now extends full certification support to Thunderbolt™ 5.
Thunderbolt™ 5 brings significant improvements over Thunderbolt™ 4, including:
- Higher bandwidth: Up to 80 Gbps (bi-directional) and 120 Gbps (uni-directional with Bandwidth Boost)
- USB4 Version 2 (USB4v2) compliance: Thunderbolt™ 5 is built on the USB4v2 physical layer (25.6 Gbps per lane), compared to TBT4’s CIO/USB4v1 Phy.
- DisplayPort 2.1 support: Enables UHBR10 and UHBR20 for ultra-high resolution displays.
- 2 and EPR (Extended Power Range) support for higher power delivery.
- New cable ecosystem: Support for Passive 80G and Active TBT5 cables.
- Expanded topology support: TBT5 SPD, TBT5 BPD, and complex daisy-chain topologies.
Thunderbolt™ 5 and USB4v2™ share the same physical layer, but are certified through different programs. Thunderbolt™ 5 certification is managed by Intel and includes additional requirements for performance, interoperability, and display support that go beyond the USB4v2 baseline. Vendors wishing to use the Thunderbolt™ name/icon/logo must pass Intel’s Thunderbolt™ 5 certification program. Those who only require USB4v2 branding may follow the USB-IF’s USB4v2 certification process.
Allion now offers Thunderbolt™ 5 Host Certification
Allion currently provides Thunderbolt™ 4 and Thunderbolt™ 5 host and device certification testing. Well-trained engineers and state-of-the-art testing instruments are ready to serve our customers. Thunderbolt™ 5 Host Testing services include Electrical Validation (EV) and Functional Validation (FV) to validate signal integrity and interoperability of your products, respectively.
Thunderbolt™ 5 EV covers the following physical layer categories:
- USB4v2 Phy – 25.6 Gbps TX/RX (Preset Calibration, TX Eye + Jitter, RX Tolerance)
- USB4v1 Phy – 20 / 20.6 Gbps TX/RX
- 2 20G Phy
- USB2 Phy
- DisplayPort 2.1 Phy (UHBR10 / UHBR20)
- TBT5 Power (80 Gbps / 120 Gbps)
- 2 / EPR (Extended Power Range)
- Return Loss & Integrated Return Loss (IRL) @ 25.6 Gbps
Certification stages:
- Stage 1. Pre-EV (pre-compliance check)
- Stage 2. EV Cert – USB4v2 Electrical CTS (USB-IF authorized lab)
Thunderbolt™ 5 FV covers the following topology and scenario categories:
- TBT3 SPD / TBT3 BPD topologies
- USB2 / USB3.X topologies
