USB's Limitation |

We are all familiar with USB (Universal Serial Bus), which lives up to its name being probably the most universal data transfer method available. The reason why so many manufactures of computers embrace it, and so many consumers require it, is because of its ease of use and seemingly unlimited array of applications. First of all, it is easier to use than almost all interfaces. Previous to USB, computers used serial and parallel ports to control devices and transfer data. These interfaces were difficult to use because you had to line up numerous pins to holes to plug the interfaces in. USB is easy, employing a plastic tongue lined with pins that inserts easily into the port. It is also impossible to insert the USB interface upside down. Another factor that makes USB so universally accepted is its 480 mbps transfer rate, pretty much skunking the transfer rate of any other inteface that is universally used by the majority of consumers. With every silver cloud is a cloudy lining, so what is USB's main drawback? USB's main limitation is its length limitation. It can only travel up to about 16 feet before the signal degrades and dies. There are a couple of solutions to this problem, however. You can either go with a USB cable with built-in active electronics (aka a repeater) for shorter distance extending, or you can go with a Cat5 extender for longer distance extending. For extending to long distances, say, 150 feet, I'd recommend Gefen's USB 2.0 Cat5 extender, part number EXT-USB-2.0. This extender uses a sender unit and a receiver unit to send the USB signal over inexpensive Cat5 cable for up to 150 feet. Article Source: http://www.ArticleBlast.com |
