This USB Repeater Cable is not a passive extension cable. It is an active device. The USB signals going in and out of the extension cable are buffered to assure signal quality and the meeting of the USB's Electrical and Timing Specifications. Using passive cables for the porpose of extension will result in signal errors and is not recommended.

This USB Repeater Cable allows a USB device to have its cable length extended by up to an additional 80 feet* by serially connecting these 16 foot cables. The USB Repeater Cable acts as a transparent USB Hub and buffers all downstream and upstream data traffic.

* Although it is possible to use multiple USB Repeater Cables in a row (up to 5), users should verify that adding the cables do not affect the operation of the USB device.
