QNAP Active Thunderbolt 3 Cable (4.9')

The QNAP CAB-TBT315M-40G is an active Thunderbolt 3 cable that delivers up to 40 Gb/s of bandwidth across its 4.9-foot length. Each USB-C connector houses a dedicated microchip that preserves signal integrity from end to end, so large files move quickly and reliably even when your devices sit farther apart than a standard passive cable allows.

This model is purpose-built for high-speed, point-to-point links between Thunderbolt 3 computers and peripherals. Use it to connect a QNAP Thunderbolt NAS to a Mac or Windows workstation when editing 4K footage in real time, to hook a laptop to a high-performance external SSD array for rapid backups, or to tie a desktop to a Thunderbolt docking station that keeps everything on your desk running at full speed. The 1.5 m reach gives you flexible placement without cluttering your workspace.

Because the cable is engineered exclusively for Thunderbolt 3, it does not carry DisplayPort Alternate Mode or USB 3.1 Gen 1/2 signals. That singular focus helps ensure stable, top-tier performance for users who depend on the full Thunderbolt specification, such as creative professionals, IT administrators, and anyone moving data-heavy projects between fast storage and equally fast computers.
