    Anyone come across one?

    I'm looking for:
    40Gbps
    USB 3 (10gbps)
    100w

    Apple sells a belkin one, but its 60w. If there aren't any, I may just pick that one up while it's on sale.

    CalDigit also sells those via their website. Even a 2 meter one.

    Unfortunately, you cannot get a cable that is both more than 0.5m and has USB 3 backwards compatibility.

    This is because cables longer than 0.5m are active (rather than passive). This is reflected in the specs for the Belkin cables you mentioned.

    However, CalDigit sells a 0.5m, 40GBps, USB 3, 100W cable.

    I'm fine with 0.5 meter, but I can't find a 100w version.

    Your wording is not correct here. What you meant is that you cannot get a cable longer than 0.5m that does Thunderbolt AND USB. USB does support cables longer than 0.5m though (even at USB3.1 Gen 2 speeds), it is part of the standard (see table on page 27; also check out the zip-file from USB-IF with the full specs). The same applies to Thunderbolt although those cables will be active and that breaks backward compatibility with anything that isn't USB2.0.

    @MrX8503 check out CalDigit's page about their Thunderbolt 3 cables: CalDigit Thunderbolt™ 3 Cables. Mind you, they only tell the Thunderbolt side of things. Basically their cables are just beefier which allows for a higher current to flow through the cable.

    I must respectfully disagree - "backwards compatibility", and the topic of the thread, meant I was obviously talking about a Thunderbolt 3 cable.

    Hmm, it should support full USB 3 Gen 2.

    (Regarding availability, they used to have them readily available on Amazon - I would speculate that they are withholding inventory as it is the cable bundled with their Thunderbolt 3 docks.)

    Possibly. I didn't want to take the risk so I got the Belkin cable from Apple. It's also approved by Nathan K. I can live with 60w.

    Hopefully someone reviews Caldigit's 0.5m cable soon. It may be the only cable that has no compromises other than length.

    You didn't state that anywhere in your reply so for anyone landing on this part of the discussion it is most definitely not obvious what you were talking about.

    Regarding the CalDigit cables, check out 9to5mac's hands-on of the 1 and 2m cables.

    He doesn't review the 0.5m unfortunately.
