What this cable delivers

The Plugable TBT4-40G2M is an active Thunderbolt 4 cable that carries 40Gbps data, 100W power delivery and video for dual 4K or single 8K displays. It suits anyone who needs full Thunderbolt performance at a two-metre reach.

Installation and common pitfalls

Plug the male-to-male connectors into any Thunderbolt 4, Thunderbolt 3, USB4 or USB-C port; the Intel chipset handles negotiation automatically. The only frequent issue is expecting dual-display output from M1 MacBooks, which support only one external screen.

Who should buy and who should not

Creators and professionals who want certified 40Gbps throughput, 100W charging and long-distance display support will benefit. Buyers who only need basic USB charging or data at shorter lengths can use a simpler, less expensive cable.

Questions about this item

How can I verify the cable is delivering 40Gbps data and 100W power after connecting it?

The Thunderbolt certification guarantees 40Gbps transfer and 100W 20V/5A delivery; your host's Thunderbolt control panel will show the active link speed and negotiated power contract.

What comes with the TBT4-40G2M and do I need a separate power adapter?

Only the 2-meter active cable is included; no power adapter is required because the cable carries up to 100W directly from the host or dock.

Should I choose the 2-meter version or a shorter length for dual 4K 60Hz displays?

The 2-meter active design maintains full 40Gbps bandwidth for dual 4K 60Hz or single 8K 30Hz without signal loss, so length is a matter of reach, not performance.
