Usb Extension Cable

The connection between a computer and a printer or scanner can usually be achieved by means of a cable extension usb cord. According to the usage instructions, the USB technology is compatible with the so-called passive extension cables, containing an active repeater chip. 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 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.

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 makes the link with the next cable, in case the scanner or the printer requires further extension. The USB connection has become all practical with the massive replacement of the former serial cable. 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 no longer incorporate serial ports, and neither mouses nor keyboards have serial connectors.

The need for a usb extension repeater cable cord is not exactly common occurrence. Most PC owners work well to the regular cable length and do not have to look for 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, 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.
