Introductions: Interfaces (ports) and Cables
Thunderbolt is the brand name of a hardware interface that allows the
connection of external peripherals to a computer. Thunderbolt 1 and 2 use the
same connector as Mini DisplayPort (MDP), while Thunderbolt 3 uses USB
Type-C. It was initially developed and marketed under the name Light
Peak,[1] and first sold as part of a consumer product on February 24,
2011.[2]
Thunderbolt combines PCI Express (PCIe) and DisplayPort (DP) into one serial signal, and additionally provides
DC power, all in one cable. Up to six peripherals may be supported by one connector through various
topologies.
Thunderbolt 2
At the physical level, the bandwidth of Thunderbolt 1 and Thunderbolt 2 are identical, and Thunderbolt 1
cabling is thus compatible with Thunderbolt 2 interfaces. At the logical level, Thunderbolt 2 enables channel
aggregation, whereby the two previously separate 10 Gbit/s channels can be combined into a single logical 20
Gbit/s channel. Intel claims Thunderbolt 2 will be able to transfer a 4K video while simultaneously displaying
it on a discrete monitor.
Thunderbolt 2 incorporates DisplayPort 1.2 support, which allows for video streaming to a single 4K video
monitor or dual QHD monitors. Thunderbolt 2 is backwards compatible, which means that all Thunderbolt
cables and connectors are compatible with Thunderbolt 1.
