I. Overview Nowadays, with the development of information technology, data transmission is very important, and it is an important subject of materials science to seek faster speed and more information transmission media for the application of high-speed computer local area network, conference TV and VOD. At present, in the process of information transmission, it is possible to use copper wire with metal as medium, quartz fiber with quartz glass as me

With the development of Internet cafes in recent years, the demand for network bandwidth has become more and more large. Traditional twisted-pair access because of the slow rate of data transmission, resulting in low network performance in Internet cafes, severely restricts the expansion of the size of Internet cafes, the adoption of new access methods has become irresistible. Optical fiber is more than traditional twisted pair to provide more networ

The application of optical fiber in various optical networks determines the requirements of optical fiber technical performance. For short distance optical transmission networks, the emphasis is on multimode fibers that are suitable for laser transmission and wider mode bandwidth to support larger serial signal transmission capacity. For long-distance submarine optical cable transmission system, in order t

This article will discuss, is not a specific case of fiber cabling, but the wiring of some of the points of attention to make a hint, in order to have the interest of friends for reference. First of all, we should understand the optical fiber communication. Fiber is the abbreviation of optical fibre, consisting of fine glass filaments about 0.1mm in diameter. It

A few years ago, people thought that the unshielded twisted pair copper cable had reached its limit in the fifth category of MHz. Many users and manufacturers turned their attention to the optical fiber and thought that the optical fiber is an inevitable transitional path for IT facilities. The optical fiber solves the disadvantages of unshielded twisted pair wir

Shenzhen first mai communication technology Co., Ltd Yellow River Vibration Fiber to the HOME--FTTH access technology as the future final, once and for all broadband access solutions, in Japan and the United States has been widely used (a total of about 5 million users), in China has been more and more attention. As the first company specializing in the development and production of optical fiber to the Ho

I. Optical Fiber1. OverviewThe optical fiber is similar to the coaxial cable, but there is no mesh shielding layer. The center is the glass core of light transmission. In multimode optical fiber, the core diameter is 15mm ~ 50mm, roughly equivalent to the hair width of a person. The diameter of the Single-Mode Optical Fiber Core is 8mm ~ 10mm. The outside of the

Detailed description of the fiber library in nodejs This article mainly introduces the fiber (fiber path) Library in nodejs. This article describes the installation, API introduction, and method usage examples of node-fiber ers. For more information, see Fiber/Optical

The optical fiber connection loss is an important parameter in the performance index of the optical fiber communication system. The loss value directly affects the overall transmission quality of the optical transmission system. During the optical fiber cable construction and maintenance testing, the use of scientific testing and analysis methods is extremely imp

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. Based on the comprehensive wiring specifications and the characteristics of Enterprise LAN construction, the selection of o

1 Overview At present, after completing the network transmission infrastructure construction, China's major communication operators have made full use of the bandwidth of the existing transmission link and sought new value-added communication services to increase business profits. The implementation of e-commerce and e-government, as well as the development of telephone bars, Internet cafes, and other small-and medium-sized Telecom customers have seen the recent boom in Man and the increase in

Optical fiber category (1) There are many types of optical fibers and various classification methods. From the material point of view According to the materials used for optical fiber manufacturing, there are Z optical fiber, multi-component glass optical fiber, plastic package layer Z core optical

The following are the two major causes of fiber loss:1 Optical fiber intrinsic lossThe intrinsic loss of optical fiber is the inherent loss of optical fiber, mainly due to the defects of the optical fiber machine matrix material quartz glass and the metal transition impuriti

brands to form an oligopoly market. Because the data center wiring market is specialized to the product, the product quality and the reliability request is far higher than the traditional wiring market, especially the optical fiber product application technology, the wiring brand still has the quite disparity, but the large-scale data center project construction and the application, has promoted the optical fiber
