The USB-C dream is to have a single cable that provides connectivity to my external displays, ethernet, USB hub, etc.
All of the components will be stored in a drawer or mounted out of view. A single, long USB-C and/or Thunderbolt 3 cable will connect the hidden messy components to the laptop on the clean visible workspace, as if you were in an Apple Store.
Unfortunately, nearly all of the USB-C and Thunderbolt 3 accessories, dongles, hubs, and docks that I want to use feature a 6-inch or shorter "pigtail" cable for connectivity to the laptop:
If I use such a device, it forces all of the DisplayPort, HDMI, ethernet, and USB hub cables to be located inches from my laptop. They cannot be hidden behind the display or mounted to the back of the desk.
What options exist for converting such a short pigtail cable to instead use a longer, nicer Apple cable?
- USB-C Coupler?
- USB-C Extension Cable?
- Some kind of USB-C hub?
- Converting the pigtail cable to a receptacle?
- Somehow opening or splicing the dock cable?
Any solution should of course pass through all of the connected ports and accessories. It should also work... which the reviews of many products state they do not.
Is there anything in the USB-C or Thunderbolt 3 spec that prevents these types of solutions from being used?
