Cable selection in cabling systems 1. cable selection should be considered based on comprehensive requirements of the system, technical performance, investment estimates, etc. In the cabling system, you should first determine the cable category and cabling composition (Shield cables, non-screen cables, optical cables, or connect them together ). 2. Select a cable

The minimum bending radius must be monitored for Cabling Standards. If the minimum bending radius is not met, the cable may be damaged and its performance may decrease. For example, in a copper system, high return loss usually indicates that the bending radius is not properly controlled during cable cabling. In an optical fiber system, high attenuation may occur. These effects may only appear at one wavelength. However, using the correct installation technology to prevent possible damages is equ

Why do strong and weak current cables need to be separated? This is because there is a magnetic field around the strong current, if the strong current Weak CurrentWiring distanceWhen it is too close, it will affect the weak current signal. The specific manifestation is: if it is a cable TV line, the signal will not be very clear; if it is a telephone line, the phone will be noisy; if it is a network cable, the network transmission speed will be affec

A small company encountered some problems on its LAN. After some tests, a technician determined that the copper media supporting the LAN experienced abnormal signal attenuation. What are the possible causes of this problem? UTP unshielded twisted pair cables) What are the causes of Crosstalk in cables? What are the consequences of Crosstalk in networks with high transmission frequencies? Abnormal signal att

The quality of twisted pair wires may affect the overall network performance during network construction. The connection of twisted pair wires between various devices is also very exquisite and should be connected according to specifications. This article mainly introduces the standard connection method of twisted pair wires and their connection methods with various devices. The purpose is to keep everyone familiar with the rules, improve work efficiency, and ensure the normal operation of the n

There are still many things worth learning about integrated network cabling. Here I will mainly explain to you how network cabling works in integrated network cabling, this includes network cable Testing, one-by-one enabling of computers, "Hot swapping" of Network cables, and big data copy methods. I believe you will understand this article and help you solve related problems. During the establishment of a LAN, according to the general specification o

How do I deal with lightning protection requirements of optical fiber cables during integrated cabling? With the development of the network, optical fiber is a medium used to transmit data in the Integrated Wiring System. Because of its advantages such as high transmission rate and long distance, optical fiber is increasingly used by people. As we all know, optical fiber is non-conductive and can withstand the impact of current, optical fiber also ha

Dynamic notices are undoubtedly a growing market. In the retail environment, it can run a variety of applications. For example, retail virtual notices running on UTP (unshielded twisted pair pairs), also known as Category 5 cables, include news and information content that entertain customers and stay online at the grocery store; elevator room advertisements, menu contents in fast food restaurants, etc. With the emergence of powerful computers, comple

Four flame retardant grades for cat6 Network cables Nowadays, many data centers use over six types of transmission media, so they have high requirements and require superior performance. In integrated wiring, many large data centers need to design fire prevention devices. Therefore, the cat6 Network cables of flame retardant materials are one of the most important choices, many developed countries in Europ

Before the emergence of the cat6 system, the traditional four-to-eight-core copper cable system had only five or more transmission performance levels, and the system's transmission bandwidth was only 100 MHz, the bandwidth requirements of the new six-category system will exceed 150% of the traditional five-category/super five-category system. To meet this new requirement, a large number of electrical parameters, especially crosstalk parameters, that were not previously specified in the era of fi

1. photoelectric signal conversion method For a long time, people have been using copper wires to transmit sound and information. However, more and more fiber cables have been used recently. Due to cost problems, we cannot replace all copper wires with optical fiber cables at once. However, to convert some cables into optical signals, the most important thing is

Comparison of several types of Integrated Wiring and optical fiber cables What is indispensable in the process of Integrated Wiring is optical fiber cables. What are the advantages of optical fiber cables? The cable type should be comprehensively considered from the cable usage, required transmission capacity, transmission bandwidth, and price. Cable types inclu

Recently, the same-quality carbon nano-optical fiber can carry more current than copper cables, according to the latest research from the US site University. The current transfer capability of individual nanotubes is 1000 times that of copper. However, the ability to merge nanotubes into optical fibers using other technologies cannot be achieved. However, a series of experiments show that the carbon nanotubes in wet spinning have superior conductivit

The International Cat 6 copper cabling system standards mainly include ANSI/TIA/EIA568B.2-1 in North America, and the International Standard ISO/IEC11801: 2002 also specifies the definition of Class E cabling systems, the two standards have been promulgated for more than five years. We can see that in the current wiring selection of new buildings, Category 6/Class E wiring has become the preferred choice for medium and high-end domestic users. However, after more than a decade of development, th

The challenge of shielded and unshielded cables, and which cables provide the best solution for copper Structured Cabling networks have been around for a long time. Selecting unshielded twisted pair wires (UTP) and tin foil twisted pair wires (FTP) (or the well-known shielded twisted pair wires (ScTP) in the United States) is not an easy decision. In fact, choosing appropriate shielding technologies from va

There are two international standards for the production of twisted pair wires: EIA/tia568a and EIA/tia568b. There are two main connection methods for twisted pair wires: straight-through cables and cross cables. Simply put, the straight-through cable means that both ends of the crystal head adopt the t568a standard or the t568b method at the same time, while the crossover cable is made of the t586a standar
