Plugable’s New Thunderbolt™ 3 cables

Today Plugable is releasing the latest additions to our growing line of Thunderbolt™ 3 products: our 40 GB 0.5 meter (TBT3-40G50CM), 20 GB 1 meter (TBT3-20G1M), and 20 GB 2 meter (TBT3-20G2M) Thunderbolt 3 cables.

Our new line of three Thunderbolt 3 cables allows for the connection of all types of Thunderbolt 3, USB, and DisplayPort devices to a Thunderbolt 3 enabled system and provides our customers choice and flexibility in terms of the cable length, bandwidth, and cost.

Thunderbolt 3 brings data transfers at speeds up to 40Gbps over USB-C, enabling a superset of standard USB-C to truly enable 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).

The Plugable Thunderbolt 3 40Gbps USB-C Cable (TBT3-40G50CM) is 50cm long (1.65 feet) and supports data transfer speeds four times faster (40Gbps) than standard USB-C cables. 40Gbps bandwidth allows dual 4K@60Hz video (or a single 5120×2880@60Hz) output and up to 60W charging capabilities when used with compatible systems and Thunderbolt 3 accessories. The cable is electronically marked (e-marker) with an IC to assist in negotiation of charging rates and USB-C alternate modes, and allows for daisy chaining up to six Thunderbolt devices.

For those who prefer a longer cable and don’t require Thunderbolt 3’s maximum 40Gbps bandwidth, the Plugable Thunderbolt 3 20Gbps 1m/3.3’and 2m/6.6′(TBT3-20G1M & TBT3-20G2M, respectively) cables support twice the speed and bandwidth (20Gbps) of standard USB-C cables. Single 4096×2160@60Hz (4Kp60) video output and up to 60W charging capabilities with compatible systems and Thunderbolt 3 accessories. The cable is electronically marked (e-marker) with an IC to assist in negotiation of charging rates and USB-C alternate modes, and allows for daisy chaining up to six Thunderbolt devices.

Our Thunderbolt 3 cables join our existing family of Thunderbolt 3 Dual Display adapters the TBT3-DP2X and TBT3-HDMI2X and will also pair well with our upcoming Thunderbolt 3 docking stations ( to provide even more expansion capabilities.

    Any timing on when you (or anyone really) will be releasing an active thunderbolt cable (40gbs) 2 meters in length?

      Hi Mike,

      Thanks for posting! We don’t have a timetable yet for an active 2 meter cable, but as soon as we do we will make a new post. To the best of my knowledge, designs for such a cable are still being validated by Intel’s engineers.

      Thank you,

      Plugable Technologies

    Bob, can you comment on the interchangeability of your cables? I already have a couple of your USBC-C100 cables. can I continue to use them with your Thunderbolt 3 docks and computer?

    Intel was very vague about this. Even now I am trying to source a 100w, Thunderbolt 3 cable. (Either 20gbps or 40gbps. Active or passive.) But for the life of me I cannot find one. Supposedly they are unobtanium.

      Hi Nathan,

      Thanks for posting! Thunderbolt 3 devices must be connected to host systems via Thunderbolt 3-branded (i.e; Intel-certified) cables to ensure proper device functionality. So while the Thunderbolt 3 cables can be used instead of USB-C cables, the reverse is not true.

      To represent it another way:
      Thunderbolt 3 device -> Thunderbolt 3 cable -> Thunderbolt 3 host

      USB-C device -> USB-C (or Thunderbolt 3) cable -> USB-C (or Thunderbolt 3) host

      Regarding 100W TBT3 cables, while they aren’t yet available hopefully that’ll change over the next year. (There hasn’t yet been a device or host which supports 5A via PD as far as we’ve seen, so a bit of a chicken/egg scenario.)

        Thanks Bob! Really appreciate the expert advice. I’ll go ahead and add this to my wishlist for when I get the Google Pixel. 🙂 According to Benson, it (and most devices currently on the market) are still Gen1/5gbps.

        The 2m one seems to be my current best bet for a “futureproof + long cord”. When the Kalby Lake based Surface Pro 5 comes out, hopefully it will ditch that proprietary MS connector and I can relegate this cord to charging+Thunderbolt 3 on that, instead of charging+USB3.1Gen1 for the Google Pixel.

        I’m with you on the 5a device issue. Again, hopefully Microsoft will pave the way with Thunderbolt 3 on the Surface, like they did AltMode with their Continuum dock.

    A 90 degree angled TB3->TB3 adapter would be perfect for users, wo want to use an wall mount. 🙂

      Thanks for feedback David! While we can’t make any guarantees regarding future products, your interest provides us with some good insight for things to consider in the future.

      Just want to second this. 90 degree adapters that can attach to an existing cable would be an amazing product. With the bend radius of existing cables, it means they extend 5-6 inches from the device before their direction can be changed.

    • Sperry Reply

      Same here! 90 degree TB3 cable is something the market is in need of.

    I need a 2m long USB-C cable to connect a MacBook 12″ with an LG ultra fine 4k display. It needs to carry 4k video from the Mac to the monitor – and Power Delivery back to the Mac (29W) – without using Thunderbolt 3 which neither device supports.

    Will your 2m Thunderbolt 3 cable achieve this? thx.

    • Joshua Henry Reply

      Thanks for asking! We have not had a chance to test our Thunderbolt 3 cables with USB-C LG monitors. On paper it should work, but there could be trouble using a cable longer than what the monitor was shipped with. USB-C can be quite sensitive to interference.

    When I touch the cable, my docking station is disconnected. Are all your cables of such a poor quality?

    • Joshua Henry Reply

      Hi John,

      As with any mass produced consumer electronics product issues sometimes can and do occur. We offer at least a 1-year warranty or longer on all of our products and are happy to replace the cable if needed.

      We’ve not had many issues with our Thunderbolt 3 or USB-C cables, so I expect that a replacement cable will probably resolve this issue for you unless there is some kind of damage to the USB-C/Thunderbolt 3 port on your computer or possibly the dock itself. Just contact us at and we’ll be more than happy to assist you with this issue.

      Best wishes!
