In addition to an extra-long passive USB4 cable (CAC-2509) that lacks certification, the company has launched an adapter (CAC-2507) for connecting two cables. For users who need to cover particularly long distances, the company has introduced the CAC-2509 cable. According to Club3D, it can transfer data over more than 30 feet while remaining a passive cable. Club3D does not mention a price in its press release, but initial retailers are already listing it for over $100. It is unlikely that two CAC-2509 cables could be connected this way to create a 60-ft link.
