I. Overview The industry has been concerned about the characteristics of network data cable skins, such as whether the skin can meet the standard of flame retardant or low smoke, the presence of a high ignition point, fire resistance, and a halogen with the latter characteristic that releases poisonous gas in the combustion. Network wiring professionals and the vast number of network users even in different regions of the standard organizations, ther
1. Overview With the development of information society, network technology has become more and more complex, and as the cornerstone of the network, keel-network cable appears more important. In the current network, there are three kinds of cable media: Optical cable, coaxial cable and digital twisted
The local area network is the individual computer or the terminal, uses the communication line to connect each other, follows certain agreement, carries on the information exchange, realizes the resource sharing. Among them, communication lines, that is, transmission medium commonly used: twisted-pair, coaxial cable, optical fiber and so on. From the cost-performance and maintainability, most LANs use unshielded twisted pair (utp-unshielded Twisted Pa
Cables are the main cause of electromagnetic compatibility problems in the system. Therefore, in practice, it is often found that when the external drag cable on the device is removed, the device can pass the test smoothly. When electromagnetic interference occurs on the site, if you unplug the cable, the fault will disappear. This is because the cable is an effi
Integrated wiring system emerged Architectural pursuit of integration, intelligence, broadband, personalized information and communication network, integrated wiring System (PDS) emerged. With the rapid development of FTTB and FTTH technology, the indoor cable has been widely used in the building integrated wiring system (including horizontal and vertical wiring system). because of the special environment of indoor application, the indoor optical
How to differentiate between dual-screen and unshielded Network cables and dual-screen network cable shielding As a part of the Integrated Wiring Design and Construction, the network cable is the basic medium for most information transmission systems. Its importance is self-evident. What is the main role of this article in resolving and shielding the network cable
Have you ever had a working environment that is against your experience? But if you're in the same boat as a cable, you might be able to cause data transfer errors or network delays, or you might be able to damage the entire cable if you drive on the cable. For this, ordinary commercial cables are not even immune to the possibility. In fact, the popular commerci
Cabling Security One of the most recognized authorities is the American Insurance Business Laboratory (UL), a non-profit organization that is committed to establishing and maintaining safety standards for a wide variety of industries. UL for the wiring industry provides a large number of quality inspection services. The services provided include the following: included in the UL list. Check wiring and related hardware security levels. UL test. According to the Tia/eia wiring standard set out
Introduction With the increasing market demand for symmetric digital cables (hereinafter referred to as digital cables) for integrated cabling, many optical cable manufacturers have begun to develop and produce such cables for this manufacturer to meet market demands. At the same time, the manufacturer found that although the digital cable and the early municipal cable
the reason the network cable was unplugged: Reason one: Because the network cable interface with magnetic field or magnetic interference phenomenon caused by computer network instability computer will be prompted to be unplugged. Solution: Call local network operators to send someone to detect the problem by accessing the network cable without interference.
Basic wire and cable knowledge The manufacturing of wire and cable is completely different from that of most mechanical and electrical products. Mechanical and Electrical Products are usually assembled into parts, multiple parts are installed into a single product, the product is measured in the number of units or pieces. Wire and cable are measured in length. A

At present, lan construction has been very common, and the integration of Ethernet cards on computers is already a standard configuration. The traces of LAN are everywhere around us. A simple small LAN composed of several computers in the family, large Internet cafes in public entertainment venues, campus networks on campus, office networks in the company, and so on are all examples of local area networks. Although they have various networking modes, the current LAN networking mode is still domi

There are many things worth learning about in the Metro optical fiber cable network. Here we mainly introduce the comprehensive comparison of the optical fiber lines in the Metro optical fiber cable network. How to build a Metro optical fiber network? First, it should be based on the network structure of the man. Second, according to the construction idea of the man, the topology of the network should be fl
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
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
