Frequently Asked Questions
How far can a USB repeater or extension device actually go? It depends on the extension method. A high-quality passive USB 3.x cable can reach up to about 5 m (approx. 16 ft), while active USB extension cables, also referred as USB repeater cables, can reach up to 30 m (approx. 98 ft). USB repeaters over CAT can extend USB up to 90 m (approx. 295 ft), and USB repeaters over fiber can reach up to 700 m (roughly 2300 ft).
What is the difference between an active and a passive USB extension cable? A passive USB extension cable simply extends the connection, therefore signal loss increases with cable length and joining multiple cables can reduce signal integrity. An active USB extension cable, also referred as a USB repeater cable, includes a built-in repeater circuit that restores signal integrity, allowing USB data to travel reliably over longer distances with minimal loss.
Does a USB repeater or extension device need an external power supply? Not always. Newnex active USB repeater cables are bus-powered and do not require an external power supply. Some compact repeaters and hubs are also bus-powered, while higher-power solutions, including certain USB fiber and CAT repeaters, require an external power input.
Which USB Repeater or Extension Device type should I choose? Choose mainly based on the connection distance and installation environment. Active copper cables are ideal for in-room runs up to about 30 m (approx. 98 ft). USB repeaters over CAT are well suited for commercial in-wall installations using standard network cabling, with a typical distance up to 90 meters (approx. 295 ft) and USB repeaters over fiber are best for longer distances over 90 meters or environments requiring EMI immunity.
Do Newnex USB repeater or active cable work with older USB devices? Yes. The latest Newnex USB extension solutions, including active cables and repeaters, are backward compatible with previous USB generations such as USB 2.0 and USB 1.1.
