Plugable supports USB-C host cables up to two meters overall for its USB-C docking stations. The guide describes checking the original cable's specifications on its attached flag and choosing a replacement that matches or exceeds them. A longer cable must preserve the complete host connection requirements.

Plugable also describes combining its one-meter extension with the original one-meter cable for a two-meter total. It does not support third-party extensions, signal repeaters, or longer overall runs. Measure the actual desk route before moving a dock far from the host, rather than adding multiple extensions after the setup is installed.
