Universal USB4 cable for Thunderbolt

The LUOM TJ-A323 is a 1.6ft USB4 Gen 3x2 cable with USB-C male connectors on both ends. It supports Thunderbolt 3 and Thunderbolt 4 hosts and peripherals, plus backward compatibility with earlier USB-C standards. The cable delivers up to 40Gbps data throughput, 100W Power Delivery charging, and 8K@60Hz video output for professionals and power users who need one cable for docking stations, high-speed storage and displays.

Plug-and-play installation with Alt Mode requirement

The reversible USB-C connectors make physical connection straightforward, but video output only works when the host port supports DisplayPort Alternate Mode. Without Alt Mode the cable will still carry data and power, yet no external monitor signal will appear. Users sometimes assume every USB-C port drives video; checking the port specification first avoids a non-working display setup.

Verify host capabilities before ordering

Confirm that your laptop, dock or device provides a USB-C port with DisplayPort Alternate Mode if you need 8K or dual 4K video. Ensure the charger and device both support USB PD 3.1 or earlier standards to reach 100W charging. The cable is Thunderbolt 3 and 4 certified, so it works with those hosts, but it cannot add video or high-wattage charging to ports that lack the necessary protocol support.

Questions about this item

How do I confirm the cable is delivering 40 Gbps after I connect it?

Use a compatible host and storage device that both support USB4 Gen 3x2, then run a large-file transfer; sustained read speeds near 2.8 GB/s and write speeds near 2.1 GB/s indicate the link is operating at its rated 40 Gbps.

What comes in the box and what must I supply separately?

The package contains only the 1.6 ft USB-C male-to-male cable; you must provide a USB-C power adapter that supports PD 3.1 or PD 3.0 PPS for 100 W charging and a DisplayPort Alt Mode source for 8K or dual 4K video.

Which version of this cable should I choose for 100 W charging and 8K video?

The TJ-A323 model is the only version listed and already supports 100 W (20 V/5 A) power delivery, 8K at 60 Hz, and 40 Gbps data transfer, so no alternate capacity or version selection is needed.
