the time domain reflection technology of the test instrument. Based on the location of the short-circuit point, determine whether the problem occurs at the connection point or between the cable to quickly troubleshoot the fault.
1.3 cross: this problem is generally caused by negligence during cabling. This situation is easy to appear in some brands of cables, because the core and secondary colors of these cables
course, the network performance degradation caused by the mismatch between the connectors also belongs to the above factors. Here, we will only discuss the optical fiber network.
In current generic optical fiber cabling networks, the process and quality of optical fiber cables used for cabling are generally stable, therefore, most of the characteristics of optical fiber cables consisting of optical fiber
network cabling, this article mainly introduces the correct identification and selection of five types of UTP.
1. transmission speed
The quality of twisted pair wires is one of the key factors that determine LAN bandwidth. Some manufacturers wrap line pairs used in Class 3 or Class 4 UTP cables in Category 5 UTP, which is difficult to identify for general users. The so-called "five types of UTP" cannot reach a data transmission rate of Mbps, and the

Integrated Wiring is a modular and highly flexible information transmission channel between buildings or buildings. It connects voice, data, Image devices, and exchange devices to other information management systems, as well as external devices. It also includes all cables and related connection components between the connection points of the external network or telecommunication lines of the building and the application system equipment. The detewel
More attention should be paid to the standardized installation of category 6 network cable demand
At present, although optical fiber has become a buzzword, many related projects are also being implemented. However, due to the technical level, general demand and price factors, it is not possible to form a universal demand product in the market. Currently, copper cables are still the mainstream in network cabling products. The performance of cat5e and
include:
(A) Cable Tension
Do not exceed the cable tension specified by the cable manufacturer. If the tension is too high, the cable line in the cable will be deformed against the twisting distance, seriously affecting the ability of the cable to suppress noise (NEXT, FEXT and derivatives), and seriously affecting the structured ripple loss of the cable, which will change the cable impedance, damage overall ripple loss performance. These factors are important factors in the transmission of Hi
Structured Cabling System inlet-cabling infrastructure affected
Impact on the Performance of Electronic Devices
Structured Cabling System inlet may have a major impact on the ability of cables to support high-speed data applications (such as fast Ethernet and Gigabit Ethernet. In some cases, cables that are close to the maximum link length specified by the standard (so close to the attenuation budget limit)
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 commercial 5e type unshielded twisted pair (UTP) Ethernet cable is very vulnerable to industrial s
End users, or any user who pays for the network connection failure, will pay attention to a major issue of cable, which is why the cable fails. Any network that uses optical fiber cables, its Optical Fiber Links are crucial to the performance of the entire network. Therefore, it is critical to ensure that the optical cable link is always in the optimal state. To help you understand the causes of Optical Fiber failure, Fluke network independently inves
With the rapid development of computer technology and the demand for fast communication, the demand for network speed is increasing. As a network communication platform, the bandwidth of the Integrated Wiring System is also increasing. The Integrated Wiring System has grown from Category 5 to Category 5. Currently, Category 6 and Category 7 are gradually accepted by users. After nearly four years and more than a dozen revisions, in June this year, the ANSI/TIA/EIA 568-B copper cable twisted pair
This article gives you a detailed explanation of Several misunderstandings about the requirements of the Integrated Wiring System. Many people may not be familiar with the requirements of the Integrated Wiring System. It doesn't matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will give you a better understanding of the requirements of the Integrated Wiring System, and I hope you can learn more through this article.

In the Integrated Wiring System, steel pipes are used for horizontal cables as much as possible, and bridges are used for laying trunk cables as much as possible. Then, during the construction process, do a Good Job of grounding cross-connection between steel pipes and steel pipes, between steel pipes and bridges, and between bridges and bridges. In such a pipeline, we will
based on North America's cable Fire standards UL and NEC (National Electrical Code), parts of Europe, the use of low halogen or low smoke halogen-free green cable standards.
Two. Halogen and halogen-free properties of wire and cable skins
In most parts of the world, electricity and telecommunications cables are currently installed with halogen, which emits poisonous, foggy chemicals when burned. In the fire, the halogen cable will produce acidic ga

We know that computer networks are divided into peer-to-peer mode and Client/Server (C/S)/mode based on their working modes. Peer-to-peer mode is usually used in home networks, enterprise networks generally adopt the C/S mode. This is because the same waist triangle model focuses on network sha
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

1. Three-phase alternating current (AC): An electric power system consisting of three AC circuits with the same frequency, equal potential amplitude, and Mutual Difference of 120 °.
2. One-time device: the device directly related to power generation and distribution is called one-time device. Including various high voltage circuit breakers, isolating switches, busbars, power cables, voltage transformers, current transformers, reactors, li
used in home networks, enterprise networks generally adopt the C/S mode. This is because the same waist triangle model focuses on network sharing, while enterprise networks focus more on file resource management and system resource security. In addition to the application characteristics of the peer network, it is more important that it is set up in a simple way, with low investment costs and is very easy to set up. It is very suitable for families and small enterprises to choose to use. Learni
Optical fiber is short for optical fiber. It consists of a fine glass wire with a diameter of about 1mm. Because of its high transmission bandwidth and communication capacity, especially not subject to electromagnetic interference, it is favored by the enterprise LAN Integrated Wiring.
