USBC to Ethernet Cable: One Connection, Fewer Joints

Two parts means two connections and two things to lose. A single cable removes one of each.

The cable contains the same controller an adapter would. The only difference is that the RJ45 end is fixed rather than a socket.

What the Controller Does

Conversion

It converts Ethernet frames to USB transfers. The operating system sees a network interface.

Negotiation

It negotiates speed with the switch, usually 10, 100 or 1000 Mbps.

Addressing

It carries its own MAC address.

Power

It draws from the USB-C port, a very light load.

Choosing and Using

  1. Decide whether you will reuse existing patch cables or prefer one piece.
  2. Check the speed tier of the controller.
  3. Check the fixed length suits the route.
  4. Test the negotiated speed after connecting.
  5. Keep the adapter version as a spare if the cable is permanent.

FAQ

Is the cable better than an adapter?

For fixed use, yes, because there is one fewer joint and one fewer part to lose.

Does it transfer at gigabit speed?

If the controller is gigabit and the host port is USB 3 class.

Can I change the length?

No. The RJ45 end is fixed. The adapter version accepts any patch cable.

Do I need a driver?

Usually not for mainstream controllers.
