USB Cable Applications

Shenzhen KW-LINK Electronic Co.,Ltd | Updated: Jun 05, 2017

    USB, is a generic serial bus abbreviation, and its Chinese abbreviation as "through the string", is an external bus standard, used to regulate the computer and external equipment connection and communication. Is applied in the PC field interface technology. The USB interface supports plug-and-play and hot-swapping of devices. USB at the end of 1994 by Intel, Compaq, IBM, Microsoft and other companies jointly proposed.USB CABLE

   Universal serial bus is connected to the computer system and external devices, a serial bus standard, but also an input and output interface specifications, is widely used in personal computers and mobile devices and other information and communication products, and extended to the photographic equipment, digital TV (set-top box), game consoles and other related fields. The latest generation is USB 3.1, the transmission speed of 10Gbit / s, three-stage voltage 5V / 12V / 20V, the maximum power supply 100W, the new Type C plug is no longer positive and negative.USB CABLE

    At present, the computer's USB interface has been widely used, generally each computer has a number of USB port. When the USB communication distance of more than a few tens of meters, the use of cable connection programs and even wireless solutions have been unable to achieve, only the current fiber can achieve USB remote communication. This article describes a number of optical through the realization of USB remote communication program.

USB port has become the most important external interface of the computer, almost all external interfaces can be replaced. The USB specification specifies that the USB communication distance is up to 5 meters (with USB-HUB). There is also a USB remote extender with RJ-45 cable, which is said to be 50 meters. Farther USB communication is currently only possible with fiber: multi-mode fiber farthest 4Km, single-mode fiber farthest 40Km.USB CABLE

   First understand the usability of USB, also understand the importance of USB. According to the versatility of the use of several commonly used external interface queuing: USB ≥ Ethernet port> serial> PS / 2, print port and so on. USB port can be easily converted out of the Ethernet port, serial port and PS / 2 port, print port, and even audio, video port and so on. In turn, the serial port and PS / 2 port, print port, etc. can not generate USB port, because the USB specification is more complex. Only the Ethernet port plus power can generate USB port, and the need for specialized software support. Of course, the computer's internal bus interface is the most versatile: the desktop PCI port, the notebook's PCMCIA port can generate USB port, and no driver.
