Usb Extension Cables
The connection between a computer and a printer or scanner can usually be achieved by means of a cable extension usb cord. 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. The maximum optimal distance for the USB extension is 16 feet, anything beyond this, may result in damage of the USB equipment and data loss. 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. 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 work with with Macs and PCs alike and any high-speed USB corresponds to the compliance protocol, whether it is 1.0, 1.1, or 2.0. The built-in electronics provide reliability to the USB cables maintaining a good operation mode both at longer distances or peripherally.
The cable extension USB connectors are different, there is one type A male and one type A female, each for a distinct part of the cable. The A female connects to the computer port while the A male connects to 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 any portable or desktop device now incorporates and solely relies on USB technology. Modern computer and notebook versions no longer incorporate serial ports, and neither mouses nor keyboards have serial connectors.
A usb 2.0 active extension cable cord is not frequently required by users. Most PC owners have enough length in the cables 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 the connection of office electronics, thus networks can be created on 16-foot distances.
