Advanced Imaging Reveals the Sophistication of Apple’s Thunderbolt 4 Pro Cables. Apple’s premium Thunderbolt 4 “Pro” cables, which come with a steeper price tag than your typical USB-C cables, are available in lengths of 1 meter (priced at 79.00 euros), 1.8 meters (149 euros), and 3 meters (179.00 euros). They offer impressively fast data transfer speeds: up to 40 Gbps with Thunderbolt 3, Thunderbolt 4, and USB 4, and up to 10 Gbps with USB 3. This makes them notably swifter than standard USB-C cables.
To shed light on why these cables command a higher price, Lumafield employed an x-ray scanner akin to those utilized in computed tomography. The results provide a deeper dive into the internal structure and materials that contribute to the cable’s enhanced capabilities.
Though previous studies have already touched upon the materials and the inherent intricacy in crafting these cables, Lumafield’s examination offers a fresh perspective. By harnessing the Neptune scanner, an industrial-grade CT scanning technology, they managed to generate a detailed 3D portrayal of both the outer and inner facets of the cable. This approach enables a visualization of otherwise hidden features.
One key revelation from the scan was Apple’s implementation of a 9-layer PCBA (Printed Circuit Board Assembly) alongside all 24 connector pins.
In addition to the advanced internal engineering, Apple’s Thunderbolt “Pro” cables are lauded for their compatibility with DisplayPort (HBR3) video devices and charging capabilities of up to 100W. The external black braided sheathing enhances the cable’s lifespan while ensuring a tangle-free experience.
For professionals or individuals who frequently handle data-heavy tasks and seek optimal transfer speeds of up to 40 Gbps, these cables, available on Amazon and Apple Stores, are a fitting choice.
