When you have to connect the computer with a USB device such as a scanner or best color laser printers, you will need a cable extension USB for the installation. The USB specifications for this kind of connection mention the possibility to have cables that include an active repeater chip, also known as passive extension cables. 16 feet is the maximum optimal distance for the USB extension, anything longer than that, may result in data loss and damage to the USB equipment. Several cable extension USB items can be inter-connected for a longer-distance solution, but even so, the cords cannot be bound together for more than 80 feet.

Basically, the connection is the basis for the entire cable extension. USB ports on notebooks and desktops pose no compatibility problems with various USB devices. If you want high quality transfer rates of up to 480 Mb per second, you should use double-shielded cable extension USB cords. Most cables are compatible with all computers, both Mac and PC and the compliance applies to any high-speed USB, 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.

The cable extension USB connectors are different, a distinct one for each part of the cable, such as A male or A female. The A female gets into the computer port while the A male makes the link with the next cable, in case the scanner or the printer requires further extension. The truth is that as a replacement to serial devices, the USB cable connection is a lot easier and more reliable. And the usage has almost no limitations at all if we think that the USB technology stays at the basis of every modern electronic device. Modern notebook and desktop versions no longer incorporate serial ports, and neither mouses nor keyboards have serial connectors.

A cable extension USB cord is not frequently required by users. Most PC owners have enough length in the cables and do not need extensions. Or they prefer to use a device which does not need wires or any other connecting attachments other than a plain Wi-Fi connection such as wireless color laser printer. 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 the connection of 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.
