I have just ordered one of the new Nov 2018 MacBook Airs that only come with Thunderbolt 3 (USB-C) ports.



Does there exist a Thunderbolt 3 to Gigabit ethernet adapter?



Notes:



  1. I am aware of the many USB-C to gigabit ethernet adapters that exist -- but I am looking for an adapter that takes advantage of Thunderbolt 3, the lower latency, and lower overheads. For example, on my old MacBook Air (2014), I use a Thunderbolt to Ethernet adapter ---> NOT a USB to Ethernet adapter.


  2. I am aware I can buy a Thunderbolt 3 to Thunderbolt adapter, and then plug in my Thunderbolt to Ethernet adapter ... but I don't want a double dongle. Who does?


Just looking for a simple clean solution.



Note on the USB-C to Ethernet that Apple sells (Belkin)



If you read the reviews on the USB-C to Ethernet adapter that Apple officially sells (made by Belkin), there are a number of reviews that suggest that speed is throttled by using the USB-C adapter (compared to Thunderbolt).



A review by Elias A states:




"Compared the old macbook dongel that has thunderbolt with this one. Got close to 1000Mbits. With this Belkin USB-C dongel I get around 200-300 Mbits"




A review by William S states:




Not really gigabit
This adapter is only recognized as a 100BaseTX, even if you try to set it manually. Returned it and bought a Thunderbolt 3 (USB-C) to Thunderbolt 2 adapter since I already had an old Thunderbolt to Ethernet adapter from Apple. This combo may not be elegant, but it gives me full gigabit speed




It is these reviews that prompted my question. There are other reviews that note that Thunderbolt also involves lower system resources than USB-C.

          Thunderbolt 1 supports 10GB symmetric (10GB each way), Thunderbolt 2 is 20GB symmetric, and Thunderbolt 3 is 40GB symmetric. USB-C on Macs support USB3.1, which supports 10GB symmetric.



          For Ethernet, nearly all devices now support Gigabit Ethernet at most, which is 1GB. 10GB Ethernet is, as expected, 10GB, though few devices support this, and even fewer homes or even businesses have it.



          Even the fastest Ethernet, 10GB, is easily supported by USB-C, so offering a Thunderbolt 3 to Ethernet adapter serves no benefit. For this reason, most such adapters are USB-C, which does support the full speed of Ethernet. Note that if you were to extend Thunderbolt using a Thunderbolt cable in order to reach say, your router, Thunderbolt is limited to cable lengths of half a meter, after which speed slows. (Thunderbolt cables are probably too expensive to even consider this option.)



          Simply purchase the Belkin USB-C to Ethernet adapter and enjoy your highspeed Ethernet.

          The only Thunderbolt 3 Ethernet adapters I'm aware of are either part of TB3 docks or really bulky 10GigE Ethernet adapters.
          A USB-C GigE adapter will do just fine. I got one by Aukey for about 10€ which works pretty much just like the TB2 Ethernet adapter from Apple (it even looks the same). Same speed (100+ MB/sek realworld speed to my NAS), no latency or overhead issues.

            We use the Belkin USB-C on all our thunderbolt 3 Macs and get speeds far in excess of the review people. I would expect they either got a bad adapter (it happens - even the best hardware companies can't ship every product perfect - that's what warranty support and service are for - to fix that).



            We've never had a case where we needed to get a more expensive 10 GB adapter in our experience. We also get 500 to 700 MBps from the MacBook which only does USB with the Belkin adapter.



            I would get those until you have a specific case you can't fix with networking checks and quality switches rather than spend more on an exotic combination of 10 GB adapters that run $200+ from the good vendors:



            • https://www.sonnetstore.com/collections/thunderbolt-10gbe-adapters/products/solo-10g

            • https://www.sonnetstore.com/collections/thunderbolt-10gbe-adapters/products/twin-10g-thunderbolt3-edition

            Sonnet's Thunderbolt 2 adapters do very well in our high bandwidth use cases - MacPro serving files or accessing a SAN as do their thunderbolt to SFP adapters. They are pro supported and designed gear for always on use. We rarely if ever need to put them in a design studio or for ProSumer use, but if you have the funds, these are fun adapters that really work well.



            For 95% of our use cases - the Belkin is the adapter to choose.

                      Sonnet's Thunderbolt 2 adapters do very well in our high bandwidth use cases - MacPro serving files or accessing a SAN as do their thunderbolt to SFP adapters. They are pro supported and designed gear for always on use. We rarely if ever need to put them in a design studio or for ProSumer use, but if you have the funds, these are fun adapters that really work well.



                      For 95% of our use cases - the Belkin is the adapter to choose.

                        We use the Belkin USB-C on all our thunderbolt 3 Macs and get speeds far in excess of the review people. I would expect they either got a bad adapter (it happens - even the best hardware companies can't ship every product perfect - that's what warranty support and service are for - to fix that).



                        We've never had a case where we needed to get a more expensive 10 GB adapter in our experience. We also get 500 to 700 MBps from the MacBook which only does USB with the Belkin adapter.



                        I would get those until you have a specific case you can't fix with networking checks and quality switches rather than spend more on an exotic combination of 10 GB adapters that run $200+ from the good vendors:
