Apple’s new 3m-long Thunderbolt 4 Pro cable is now officially available to purchase for a steep $159. While that price tag might sound insane, it’s currently the longest Thunderbolt 4 cable on the market. Passive Thunderbolt cables have a maximum length of about 0.8m, but this is an active cable. That means there are chips and retimers inside of it working together to reduce signal jitter. You can check out the teardown of the 1.8m version of this cable here.
The cable supports a bevy of standards, including Thunderbolt 3, Thunderbolt 4, and USB 4 data transfers up to 40Gb/s, DisplayPort video output (HBR3), as well as up to 100W of power delivery. It’s also braided to prevent tangling, a nice feature to have, considering the price. However, if power delivery is all you’re after, check out Club3D’s new USB Type-C cables that can deliver up to 240W of power. They will probably be priced way lower, although the 40Gbps-capable one is limited to just 1m.
