In the formation of local area network, in accordance with the general wiring of generic specifications, the construction should be used with "rice standard" network cable or on both sides of the crystal head set dedicated "special-shaped number", and in the cabinet to do with "rice mark" or "Number tube" corresponding to the computer identification record Many units have a small number of original computers, later, gradually added some computers, com

Wireless router Setup is more and more simple, but now is the router installation and network connection is not a lot of netizens. How to connect the router network cable? In fact, it is very simple, today's triple small series for you to share the most common 3 kinds of wireless router cable connection methods. Router network cable How to connect 3

Ethernet (EtherNet)Originally created by Xerox, the Ethernet was developed jointly by DEC, Intel and Xerox three companies in 1980 as a standard. Ethernet is the most widely used local area network, including standard Ethernet (10Mbps), Fast Ethernet (100Mbps), Gigabit Ethernet (Mbps), and 10G Ethernet, all conforming to the IEEE802.3 Series standard specification.(1) Standard EthernetThe first Ethernet only has a 10Mbps throughput, and it uses the access control method of the CSMA/CD (carrier-l

advent of optical fiber communication technology, the large potential bandwidth capacity of nearly 30THz has brought the flourishing opportunity to the communication field, especially since the information superhighway was put forward, the optical technology began to permeate the whole communication network, and the optical fiber communication has the trend of advancing to all optical network. Optical fiber communication has gone through more than 20 years in our country. The market is the life

As we all know, the network cable is one of the most basic hardware facilities for us to access the Internet and the most inconspicuous equipment. We are used to purchasing a ready-made network cable. We seldom care about how the network cable is made. We only know that the network cable must be composed of eight cores

A sound video transmission design is a very important part of the CCTV system. If a set of built systems choose cameras, lenses, monitors, and video recorders that can produce or process high-quality images, but there is no good transmission system, eventually, the images seen on the monitor will not be satisfactory. According to the "barrel rule", the final image quality will depend on the worst part of the entire system, which is often the transmission system. System designers and installers m

Now is a network of the world, the network to hundreds of millions of computers, notebooks, tablets, mobile phones together. The network connection way, divides into wired and wireless two kinds. Wired connections are basically connected by a network cable. So it is necessary to know the network cable. One, the network cable, also known as twisted pa

The application of optical fiber cables in telecommunications and long-distance communication networks has become very popular and mature. In recent years, with the application of Gigabit Ethernet and the gradual arrival of 10-Gigabit Ethernet, more and more applications of optical cables in LAN have been made. In recent years, local area networks, man networks, campus networks, and campus networks have almost all been laid with optical cables, and the proportion of optical fiber cables is growi

Internet access in China has developed very rapidly. It may not matter if many people do not know about cable modem in Internet access. After reading this article, you must have gained a lot, I hope this article will teach you more things. When cable modem uses a cable TV network for high-speed access, the general connection mode is: one end is connected to a com

Ethernet is the undisputed overlord of the Internet world. It has been firmly occupying the territory of commercial office environments in recent years. The field of control and automation is also moving towards this open, standards-based technology. Do you think the cables used at the reception desk can also meet the demanding requirements of industrial process control and automation technology environments? In fact, COTS (Popular) 5e unshielded twisted pair (UTP) Ethernet cables are very fragi

performance is required. A high-speed optical fiber cable network needs to properly select the appropriate testing instrument. Laser and LED The laser emitting power is very high, and the emitted light is very concentrated, while the light emitted by the LED is usually scattered and the power is low. Compared with LEDs, a laser can send high-speed pulses, which is also the main reason for using a laser in high-speed networks. For Single-Mode Optical

In companies, businesses, homes, schools, as long as there are networks where there are network cables, but sometimes to add a network cable from a long way through a layer of barriers to pull the network cable to the destination, It took a lot of money. The company often want to add a machine here, there to add a punching machine. To pull the network line from the ceiling, very dirty, and black, so I had

Overview Verification-check whether the bandwidth of the existing cabling system supports voice, 10/100, VoIP, or Gigabit Ethernet Fault Diagnosis-shows why the existing cabling system cannot support network bandwidth requirements, for example, there is a crosstalk at 11 meters) Search-detect the device connected to the other end of the cable and display the device configuration speed/duplex mode/line pair) Identifies unused switch ports for easy

Make the hub port indicator flashing test 10/100 Ethernet uses time domain reflection technology TDR) to measure the cable length and fault distance. A network testing instrument that combines multiple test functions to test the functions of the UTP or coaxial cable product when a twisted pair or coaxial cable site is added, moved, or changed. Whether you are an

The horizontal cable manager is mainly used for cable connections between adjacent units and devices in the cabinet. It has a combination of 1U and 2U, single-sided and double-sided cables, covered cables, and no-covered cables. Cables can be accessed from left and right, up and down, and some of them can also be used for frontend and backend access. The vertical cable
