All Thunderbolt docking stations include the appropriate Thunderbolt cable in order to connect the docking station to the host computer. As of this writing, all Plugable Thunderbolt host cables that are included with Plugable Thunderbolt docking stations are 1.0 meter (approximately 3.3) feet in overall length.

For reference, the specifications of all Plugable Thunderbolt cables are printed on a small white cable flag attached to the cable itself.

If the original 1.0 meter long Thunderbolt host cable is not sufficient for a specific use case, longer cables of up to 2.0 meters (approximately 6.6 feet) in overall length can be purchased separately from Plugable. An example of such a cable is the Plugable TBT4-40G2M cable

Plugable does NOT support using Thunderbolt host connection cables that are over 2.0 meters in overall length with any Plugable brand product.  

Plugable does NOT support the use of any type of Thunderbolt extension cable or any type of signal repeater in conjunction with our products.

Please note, Plugable can only guarantee the performance and compatibility of Plugable brand cables.
