What is Thunderbolt?
▪ A display interface that is used for data transfer
Thunderbolt version 1 and 2
Thunderbolt version 1 and 2 used a physical connector that
were backwards compatible
Thunderbolt 1 - history
Thunderbolt 1 is the first product in the series that was integrated into the MacBook Pro laptop in the year 2011. It achieves a data rate of 20Gbps in such a way that it bears four channels of 10 Gbps each for data transmission. It uses the architecture of the Mni-DisplayPort connector under the protocol 4 x PCIe 2.0 DisplayPort 1.1a.
Thunderbolt 2 - History
Difference between Thunderbolt 1 and 2
Although Thunderbolt 2 is physically identical to its previous version, it stands out with the feature of channel bonding to simultaneously display as well as transfer a complete 4K video. While Thunderbolt 1 has 4 channels, Thunderbolt 2 combines two channels so overall it has two channels, each of 20Gbps.
Thus with the same bandwidth as Thunderbolt 1, Thunderbolt 2 causes less overhead and enables more efficient transfers.
Thunderbolt 3 - history
Thunderbolt 3 shares close similarities with the USB Type C connector. It supports a connection speed of 40Gbps per second. It is capable to supply two 4K displays simultaneously and transfer the audio as well as video files at the same time. Quick Notebook charging is another attractive feature. It was launched in the market in late 2015. Later, USB 4 was released in August 2019 based on the specification of Thunderbolt 3.
All Thunderbolt version 3 will support USB-C, but not all USB-C
we’ll support Thunderbolt 3
Max cable length for max speed is 1.6ft
What is the data transfer over cables for Thunderbolt?
Supports speeds of up to 40 gigabits per second for data transfer over cables
