A tester can complete the test of copper cables and optical cables, certification and documentation Record Filing automatically calculates the optical fiber margin and passes/does not pass the test results automatically at both wavelengths simultaneously measuring the two optical fiber cables stored in copper and optical fiber cables new model: DSP-FTA440S, DSP-FTA430S, DSP-FTA420S products function high-speed network makes the optical fiber in the construction and campus network environment can
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
With the rapid development of broadband multimedia service and optical fiber communication technology, optical fiber communication technology has been used more and more widely in the access network. In the past, optical fiber network is mainly to meet the needs of transmission network construction, access to the layer of fiber optic cable needs less, a small number of access layer cable is generally direct
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
The metropolitan area Optical cable line is mainly the pipeline optical cable, supplemented by the aerial and other laying way very few optical cables, its characteristics are: The line section is relatively short, can be divided into local trunking, user access network backbone and user to introduce optical cable, optical fiber
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
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
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
1, test the speed of network cable The transmission speed of the network cable is the most effective way to discriminate the quality of the network cable. In order to be closer to the actual use of the environment, while reducing the external interference link, the author recommends the use of two-machine direct-linked way. At the same time in order to ensure th
high-speed optical fiber cables need to be correctly selected as appropriate testing instruments. Laser and LED The laser emitting power is very high, and the emitted light is very concentrated. The light emitted by LEDs is usually scattered and the power is low. Compared with LEDs, lasers can send high-speed pulses, which is also the main reason for using lasers in high-speed networks. For Single-Mode Optical Fiber Links, Fabry-Perot laser light sources are usually used. The new VCSEL (Vertica
When dealing with computer networks, it is inevitable that network cables should be used frequently. In fact, the production of Network cables is very simple, that is, to insert the 4-to-8-Core Cable of twisted pair wires into the crystal head according to certain rules, therefore, the materials required for the production of such network cables only need twisted pair wires and crystal heads. The required tools are also relatively simple. Generally, o
In the installation of the project, due to the limited conditions, are on-site production of network cable, generally do not use instrumentation, only through the pilot indicator to determine whether the guide, but the indicators can not really reflect the quality of the network cable, the production of some of the soft fault is not found, after a period of time will gradually exposed, The following are som
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
As optical fiber transmission technology matures and the price of Optical Fiber becomes lower and lower, traditional coaxial cable transmission is increasingly unable to adapt to the development of optical network today, it has the advantages of low transmission loss, long transmission distance, working bandwidth, and strong anti-interference ability, making it the most ideal carrier for optical network communication. The optical fiber is made of extr
Fiber-optic communication is favored because of its advantages such as large capacity, high transmission information quality, long transmission distance, stable performance, anti-electromagnetic interference, and strong corrosion resistance. Especially in the last decade, with the increasing demand for broadband services, optical fiber communication has been vigorously developed. At present, the total length of optical fiber cables in China's communications industry has reached more than 2 milli
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
