A peripheral product that Apple announced earlier along with the new computer Mac Studio series, the Thunderbolt 4 Pro cable (3 meters) was priced at HK$1,169 and attracted attention. Now there are people who disassemble this expensive line to see why this line is sold at this price.
The media ChargerLAB published a video on YouTube regarding dismantling the Thunderbolt 4 Pro cable (1.8m), which also sold for HK$949 in Hong Kong. I started to disassemble the cable from the outside, and found that it uses a waterproof and dustproof braided outer layer. This braid uses a thermoplastic elastic material TPE and a film with a mask function to wrap the wire heavily. After disassembling it, it can be found that there are a total of 19 wires wrapped in it, of which 5 wires are tinned copper wires for power supply, and the other wires are made of pure copper or silver-plated materials, and there are also 2 white plastic wrapping live wire for USB 2.0 transfer and Thunderbolt 3 compatible.
In the connector part, you can see that the cable is protected by a rather hard plastic hard shell and a brass sleeve. It contains an Intel chip, which is responsible for the Thunderbolt connection.
According to ChargerLAB, the Thunderbolt 4 Pro cable is made of a variety of high-quality materials to make it less susceptible to external interference that might affect transfer speeds. For users who need to transfer a large amount of data, it can improve work efficiency, and appreciate that this cable is a type of material rich in many cables, suitable for use with high-end computers.
