CableMAX USB 3.0 A-to-A Extension 3 ft

This CableMAX cable extends a USB 3.0 connection by three feet using a male-to-female Type-A layout. It targets users who need to reposition a printer, scanner or other peripheral away from the host port without replacing the device cable. The fully shielded, moulded construction aims to preserve signal integrity in typical desktop environments.

Sustained throughput with shielded twisted-pair

The cable uses high-quality shielded twisted-pair wiring to maintain the USB 3.0 signalling rate during prolonged transfers. By reducing electromagnetic interference, the design helps the link sustain its rated 4.8 Gbps capability rather than falling back after a short burst. This makes it suitable for long-duration scans or bulk print jobs that keep the bus active for minutes at a time.

Practical limits of the USB 3.0 interface

USB 3.0 defines a maximum raw throughput of 4.8 Gbps, which is ten times the 480 Mbps ceiling of USB 2.0. Real-world speed will be lower due to protocol overhead and host-controller scheduling, and the three-foot length is chosen to stay within the standard's loss budget without active signal conditioning. The cable cannot overcome bandwidth limits imposed by the host or device themselves.

Questions about this item

Does the cable generate noticeable heat or draw extra power during all-day transfers?

The passive Shielded Twisted Pair construction carries the signal without active components, so it adds no measurable heat or power draw beyond the host and device themselves.

What ports must my computer and peripheral already have for this cable to work?

Both ends need a standard USB Type-A socket — the host side accepts a USB 3.0 A male plug and the device side presents an A female receptacle.

Will this cable slow down a USB 2.0 printer or scanner I want to keep using?

It is backward compatible, so a USB 2.0 device will still operate at its native 480 Mbps rate when connected through the extension.
