Purpose-built extension

The SIIG JU-CB0811-S1 is a 20m USB 3.0 active repeater cable that extends a Type A connection beyond standard length limits. It targets installers and integrators who need to bridge long runs to cameras, storage or interactive displays without signal degradation.

Build integration

The cable carries a male Type A plug on one end and a female Type A receptacle on the other, weighing 1.5 kg with a supplied 5V 2.0A power adapter. Two cables can be daisy-chained to reach 40m when the external adapter is used, freeing the host port from supplying bus power to downstream devices.

Sustained operation

Fully shielded construction and an operating range of 0 to 50°C support error-free 5Gb/s throughput during continuous transfers. The plug-and-play design requires no driver installation on Windows 7, Vista or XP, and the adapter accepts 100-240VAC input for stable performance across extended sessions.

Questions about this item

Does the 20 m length still deliver the full 5 Gb/s rate under sustained use?

Yes, the active repeater design maintains USB 3.0 speeds up to 5 Gb/s across the full 20 m run.

How much heat or noise does the built-in electronics add when the cable runs all day?

The repeater operates passively within a 0–50 °C range, has no fan and draws up to 2 A from the included 5 V adapter, so it adds no audible noise.

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

A standard USB 3.0 Type A port is required on the desktop or notebook.
