ExtremeUSB®: protocol, benefits, availability and applications

Universal Serial Bus (USB) is the most successful interface in the history of the PC, with well over ten billion USB devices in the global market and counting. Due to its flexibility and simplicity, USB has become the de-facto standard for peripheral connectivity spanning broad markets and applications.

USB is designed to allow many peripherals to be connected using a single standardized interface. It provides an expandable, fast, bi-directional, low-cost, hot-pluggable, plug and play serial hardware interface allowing computer users to connect different peripheral devices into a USB port and have them configure automatically, ready for use.

As versatile as USB may be, it is restricted to an operational distance limitation of 5 meters for USB 1.1/2.0 and approximately 3 meters for USB 3.0. This persistent drawback to USB functionality was resolved by the introduction of ExtremeUSB®.

Introduced by Icron Technologies, ExtremeUSB is a series of patented technologies designed to overcome USB’s distance limitations.

This white paper takes a look at the USB specification and describes how the ExtremeUSB protocol works transparently to enable USB functionality up to 10 kilometre distances.
