They are designed to provide fast data transfer rates and support multiple protocols, including data transfer, video output, and power delivery.Thunderbolt cables use the PCI Express and DisplayPort protocols to enable high-speed data transfer and video output over a single cable. They are known for their versatility and ability to connect a wide range of devices, including external storage drives, displays, docking stations, audio interfaces, and other peripherals.Thunderbolt cables come in different versions, with Thunderbolt 3 being the most common.
