structured cabling systems. At present, the signal processing electronic technology in dealing with foreign crosstalk, compared to other sources of noise, there is no very effective way. The way to suppress this noise is to improve the performance of wiring system, so that the wiring system itself has the ability to restrain noise. The research team is exploring a range of technologies to suppress noise, or develop systems for the transmission of Gigabit Ethernet in the current noise environmen
Copper and optical cables can also be divided into two basic parts of outdoor cables and indoor cables. These cables are functionally and structurally different. For indoor use of the design of the cable, there is a flame retardant type and flame retardant type of electric-grade interior has an air core, outside a laye
In a two-way cable TV system, to make reverse transmission work normally, the confluence noise must be reduced. Most of the confluence noise is formed by a space electromagnetic interference string into the reverse system. In a Bidirectional CATV system, cables are one of the most vulnerable components to interference. In order to make the reverse system work normally, four Shielded Cables with High attenua
Indoor cables, just as in their names, are cables made for indoor applications-that is, they cannot be immersed in liquid water in this environment. No more than outdoor cables, indoor cables do not use water-resistant materials or structures that reduce water penetration.

Differences between indoor and outdoor Network cables and Network Cabling Process
Differences between indoor and outdoor Network cables
As the name suggests, an outdoor network cable is a cable used outdoors. An indoor network cable is mainly used in an indoor network cable.
The biggest difference between an outdoor network line and an indoor network line is that the outdoor network line has two layers of
First, the outer skin: Indoor optical cables are generally used polyethylene or flame-retardant polyethylene vinyl, the appearance should be smooth, bright, flexible, easy to peel. Poor quality of the optical cable skin finish is not good, easy and inside the tight sleeve, aramid adhesion.
Outdoor fiber optic cable PE sheath should use high-quality black polyethylene, into the cable after the skin smooth, bright, uniform thickness, no small bubbles.
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 twis
Introduction to the selection of optical cables for indoor integrated cabling
In the Integrated Wiring System, the optical fiber cables are upgraded between floors in the vertical system, the communication cabinets are used in small spaces, and the optical fiber cables are used on the desktop, communication applications that travel through high-pressure inflat

comprehensive solution for real-time network management and control of physical layer, helping users to build an intelligent network structure-your structured cabling system. Can realize the real-time automation and the intelligent management, can use the active equipment effectively, can the accurate consummation record document, can reduce the interruption time when repairs the fault: When the structure has the error or the fault, eliminates the time which uses to look up the problem origin.
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? What is twisted pair wires? What are STP, SFTP, UTP, FTP, and ASTP? What's the cat5e d
As the load current changes and the ambient temperature changes, the power cable will undergo thermal scaling. The great thermal mechanical force is generated due to the thermal expansion and contraction of the wire core. The larger the cable core section, the larger the thermal mechanical force is generated. At the same time, the wire core and metal jacket may also produce creep due to multiple cycles of thermal expansion and contraction. Thermal scaling poses a great threat to the operation of
1. outer skin: indoor optical fiber cables generally use polypropylene or flame retardant polypropylene. The appearance should be smooth, bright, flexible, and easy to strip. Poor quality of the outer skin of the optical cable is not good, and it is easy to stick with the tight covers and.The PE jacket of the outdoor optical fiber cable should adopt high quality black Polyethylene. After the cable is formed, the outer skin is flat, bright, thin and un
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
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
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
