When you have to connect the computer with a USB device such as a scanner or a printer, you will need a cable extension USB for the installation. According to the usage instructions, the USB technology is compatible with the so-called passive extension cables, containing an active repeater chip. The maximum optimal distance for the USB extension is 16 feet, anything beyond this, may lead to data loss and damage to the USB equipment. A possibility to make the distance longer is to connect several cable extension USB devices but not more than 80 feet, which would be approximately four regular cables bound together.

Basically, the connection is the basis for the entire cable extension. USB ports on notebooks and desktops are perfectly compatible with devices. Usually double shielded, extension cables USB applications make transfer rates possible at up to 480 Mb per second. Most cables work with with Macs and PCs alike and any high-speed USB corresponds to the compliance protocol, whether it is 2.0, 1.1 or 1.0. The reliability of USB cables results from the existence of incorporated or built-in electronics that make good performance possible even at long or peripheral distances.

There are usually two types of cable extension USB connectors, there is one type A male and one type A female, each for a distinct part of the cable. The A female gets into the computer port while the A male connects to the next cable, if you need further extension with the printer or scanner devices. The truth is that as a replacement to serial devices, the USB cable connection is a lot easier and more reliable. And the usage is omni-present if we think that any portable or desktop device now incorporates and solely relies on USB technology. Modern notebook and desktop versions don’t have serial ports any more, and neither mouses nor keyboards have serial connectors.

The need for a cable extension USB cord is not exactly common occurrence. Most PC owners work well to the regular cable length and do not need extensions. Market statistics indicate that Mac users, who have a lower number of USB ports are usually the first to seek USB connectors to match their electronic devices. Cable extension USB cords will usually function for connecting office electronics, which makes them necessary for networks, multiple office usage and lots of situations when the distance between one appliance and another is larger than 16 feet.
