Not Just a Thunderbolt 3 Cable
Thunderbolt 3 brings data transfers at speeds up to 40Gbps over USB-C, enabling a superset of standard USB-C to truly become one compact port that does it all—delivering the fastest, most versatile connection to any dock, display, or data device.
For the first time, one port can connect numerous Thunderbolt devices, any display, and billions of USB devices (additional adapters may be required). Thunderbolt 3 cables are primarily used for connecting docking stations, high performance data storage solutions, peer-to-peer networking, and more.
Note: This cable is incompatible with Qualcomm Quick Charge and other (non USB-IF Power Delivery) “Fast Charge” technologies.
The Plugable TBT3-40G80CM cable is foremost designed as a Thunderbolt 3 cable, but it is also a universal USB-C cable for use with USB-C computers, phones, tablets, docking stations, accessories, and more. It supports all USB-C cable features, including USB 3.0 and USB 2.0 data lines, wire gauge supporting up to 5A charging via the USB-IF PD (Power Delivery) standard 100W max (5V-20V), and support for reporting its capabilities as an electronically marked cable.
A Cable That Does It All
Massive 40Gbps Bandwidth
Because the cable is designed for Thunderbolt 3, it is also capable of supporting data transfer speeds four times as fast as standard USB-C cables. The available 40Gbps bandwidth allows for dual 4K 60Hz video outputs (or a single 5K output) and up to 100W (20V, 5A) capabilities when used with compatible systems and Thunderbolt 3 accessories. Please note for USB-C usage this cable is limited to USB-C 3.0 (5Gbps).

What is the maximum length Thunderbolt cable that can be used to connect a Plugable Thunderbolt docking station to the host computer?
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.
