USB 2.0 to 3.0 Type-B Extension Cable

This 30 cm cable converts a USB 2.0 Type-B male port into a USB 3.0 Type-B female receptacle, letting you connect modern SuperSpeed peripherals to legacy host ports. It suits users adding an external SSD, camera or similar device to an older computer or panel-mount enclosure without replacing the host controller.

Panel-Mount Installation Notes

The cable is designed for panel-mount use, so the female end can be secured to a cabinet or chassis cut-out to create a fixed bulkhead connection. Gold and silver-plated contacts with a welded strain-relief resist damage from accidental tugs, though the short 30 cm length limits routing flexibility in larger enclosures.

5 Gbps Throughput and Compatibility

When paired with a USB 3.0 host and device, the link supports up to 5 Gbps, which is 10 times the bandwidth of USB 2.0. The adapter will fall back to USB 2.0 speeds if either side lacks 3.0 support, so it cannot deliver SuperSpeed performance on a purely USB 2.0 system.

Questions about this item

How do I confirm the cable is delivering the 5Gbps throughput after connecting my SSD?

Connect the cable between a USB 3.0 host port and a USB 3.0 Type-B device, then run a file transfer test; sustained speeds near 5Gbps indicate the link is operating at full USB 3.0 specification.

What connectors and cable length are included, and is any extra hardware required for panel mounting?

The box contains the 30cm extension cable with a USB 2.0 Type-B male plug on one end and a USB 3.0 Type-B female socket on the other; gold silver-plated connectors and welded strain relief are built in, so no additional parts are needed for panel mounting.

Which version should I choose if my device uses a USB 3.0 Type-B port and I need a short internal extension?

This single 30cm variant converts a USB 2.0 Type-B male connection to a USB 3.0 Type-B female port, making it the correct choice for extending a USB 3.0 Type-B device inside a cabinet or enclosure.
