Plugable's Thunderbolt dock guidance describes replacing an included host cable with a supported longer cable when needed. It gives a two-meter Plugable Thunderbolt cable as an example and notes that the cable flag identifies specifications. This preserves a single defined host link instead of adding uncertain intermediate connections.

The company does not support Thunderbolt extension cables or signal repeaters with these products and guarantees its own branded cable combinations. Check the dock's current cable guidance before rearranging a workspace. The connection carries video and other dock traffic, so its reliability affects much more than simple USB peripheral detection.
