One-foot USB 3.0 extension

This JacobsParts cable adds 30 centimetres to a USB 3.0 link using a Type-A male plug on one end and a Type-A female port on the other. It suits anyone who needs a short reach increase for a peripheral without replacing the original cable. The blue jacket makes it easy to spot behind a desk. It is not for users who need a longer run or a different connector type.

Build integration

Plug the male end into the host or hub and attach the existing device cable to the female end; no drivers or external power are required. The extension frees a port that would otherwise be blocked by a bulky connector or a tight chassis cut-out. It does not add latency or reduce the bandwidth available to the attached device. Builders who need to bridge a larger gap should look for a longer cable.

Sustained-load behaviour

The cable maintains the full USB 3.0 signalling rate during continuous transfers because its conductors and shielding meet the specification for the standard. Backwards compatibility with USB 2.0 means older peripherals still operate at their native speed without negotiation errors. Signal integrity holds over the full 1 foot length even under heavy bulk-endpoint traffic. Users expecting active repeater performance for runs beyond this length will not get it from this passive cord.

Questions about this item

Will the 1 ft length limit the 5 Gbit/s signal under sustained use?

At 30 cm the cable meets the USB 3.0 length specification, so full 5 Gbit/s throughput is maintained.

Does the cable run hot or draw extra power during all-day transfers?

It is a passive copper cable with no active electronics, so it adds no measurable heat or power draw.

What port must my computer already have for this cable to work?

A standard USB 3.0 Type-A port — the cable plugs directly into it and provides a Type-A female socket.
