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

The fiber channel refers to the network channel (FC. Since fiber and re have only one word difference, many misunderstandings have emerged. FC only represents the fiber channel, rather than the fiber channel. The latter is translated as an "Fiber Channel", and even a disk w

IP protocol-based fiber channel FCIP or FC/IP is an IP protocol based on the storage network technology, which is developed by the Internet Engineering workgroup IETF. FCIP allows optical fiber channels to transmit data between SAN devices on an IP network. This capability also facilitates data sharing in a geographically dispersed enterprise. FCIP is a method for transmitting storage data through an IP net

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

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

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

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
