USB

In today's world, USB has become a widely chosen communication protocol for data transfer between computers and their peripheral devices. Initially, USB was primarily used to connect devices over short distances; however, over time, the use of USB has expanded to encompass long distance applications such as medical imaging, security cameras, and machine vision. For example, when setting up multiple USB security cameras around the house and monitoring them with a single PC, the need for longer USB transmission distances is often beyond the scope of the USB-IF standard.

According to the USB-IF, each USB standard has a clearly defined maximum length, as the signal power decreases as the length of the USB cable increases. Therefore, shorter USB connections are usually more recommended.

USB Standard Length

USB is a serial bus standard for connecting computers and devices, and has been widely used in products such as personal computers and mobile devices, and it has become a fairly common communication standard.

USB Has Become a Major Signaling Technology Today

USB stands for Universal Serial Bus, and a so-called "bus" is a circuit arrangement or communication system for transferring data between components in a system. In this case, a "serial" bus transfers data one bit at a time over a single wire. However, the USB connector can transfer more than just data between components; it can also be used to transfer power and can accommodate many different hardware devices, from printers and keyboards to cell phones and flash drives.

A communication interface is an interface used for data transfer and communication between devices. Common communication interfaces include USB interface, HDMI interface, VGA interface, Ethernet interface, wireless network interface, etc. These interfaces can be used to connect computers, external devices, network devices, monitors, printers, etc. to realize data transmission and communication functions.
