Cable sequence, twisted pair wires, and direct connections

A lan is to connect individual computers or terminals using networks to exchange information and share resources according to certain protocols. Commonly used network cables include twisted pair wires, coaxial cables, and optical fiber cables. Twisted Pair wires can be divided into shielded twisted pair wires (STP) and unshielded twisted pair wires (UTP) based on whether they are added with the screen layer of a wire mesh ). Most local networks use unshielded twisted pair wires (UTP-unshielded t

Smart Community cable selection and Comparison

What is Smart Community cable used? In the construction of digital communities, cable selection is one of the crucial links. Currently, several schemes are adopted: 1. Twisted Pair wires; 2. coaxial cables; 3. optical fiber cables.

Network cable Common Fault Analysis

During project installation, due to the limited conditions, the Network cables are all made on site. Generally, you do not need to perform an instrument test. You only need to use the indicator lights to preliminarily determine whether the network cables are turned on or off. However, the indicator lights sometimes do not reflect the network cables, some soft faults existing in the production of Network cables cannot be found at the moment. After a while, they will be gradually exposed. The foll

Cabinet cable details (1)

The horizontal twisted pair wires in the cabinet are located on the rear side of the Cabinet. In the past, the twisted pair wires were not organized or simply bundled before being immediately mounted to the distribution frame. At that time, from the back of the Cabinet, the horizontal twisted pair wires were hanging like waterfalls, or several nylon cable ties can be bundled on either side of the Cabinet. Everyone is concerned about the performance te

How Android does not debug via USB data cable

When developing an Android app, it's usually connected to the device and computer via a USB cable, but for some applications that need to use a USB device, this approach is troublesome, and the USB port of the phone is connected to the external USB device and no longer connected to the data cable. This can be done by means of a network TCPIP. That is, ADB connects devices over the network without the need f

Optical fiber and Cable

I. Optical Fiber1. OverviewThe optical fiber is similar to the coaxial cable, but there is no mesh shielding layer. The center is the glass core of light transmission. In multimode optical fiber, the core diameter is 15mm ~ 50mm, roughly equivalent to the hair width of a person. The diameter of the Single-Mode Optical Fiber Core is 8mm ~ 10mm. The outside of the core is surrounded by a glass envelope with a lower refractive index than the core to keep
