USB4 Cable 3.3 ft 40Gbps 100W

This Jansicotek TJ-A323 cable carries USB4 Gen 3x2 signals over a 3.3 ft braided USB-C to USB-C link. It delivers up to 40 Gbps data throughput, 100 W Power Delivery and 8K video at 60 Hz in a single bi-directional cord.

Suits Thunderbolt 4 and USB-C hosts.

The cord works with Thunderbolt 4, Thunderbolt 3 and USB 3.2/3.1/3.0 hosts that have USB-C ports. It cannot connect to older USB-A ports or to devices that require a proprietary docking connector.

40 Gbps USB4 Gen 3x2 throughput

The decisive figure is the 40 Gbps maximum data rate. If your workflow needs that bandwidth for external storage or dual 4K displays, this cable meets it; if you only need 10 Gbps or 20 Gbps, a lesser cable will suffice.

Questions about this item

What length and connector type does the Jansicotek TJ-A323 cable use for fitting between devices?

The cable is 3.3 ft long with USB C male connectors on both ends, bi‑directional and reversible.

How do I install the cable to get 40 Gbps data and 100 W charging, and what step is often missed?

Plug each USB C end into a Thunderbolt 4 or USB4 port that supports 40 Gbps and PD 3.1; the common miss is using a port limited to lower speeds or power.

When will the built‑in E‑marker chip need attention or the cable require replacement?

The E‑marker chip is passive and needs no maintenance; replace the cable only if the braided jacket, connectors or signal integrity become damaged.
