SDH optical interfaces are very important in programmable switches. Here we mainly introduce the design concept of SDH optical interfaces of programmable switches. With the rapid development of modern telecom networks, the synchronous digital transmission system SDH has become the dominant Transmission Mechanism of telecom networks. SDH-based transmission networks have gradually become the dominant directio

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

Absrtact: This paper describes the colorful situation of optical network world, expounds the core technology of each series of optical Network, discusses the adaptation of optical network products to IP service, and puts forward the fusion node and intelligent Optical Network technology. Key words: Synchronous Digital

A virtual optical drive is a tool for simulating (CD-ROM) work, can be generated and your computer installed on the same optical drive can be the same virtual CD-ROM drive, the general optical drive can do the same thing as a virtual CD-ROM can do, this principle is to first virtual out of one or more virtual optical d

The new generation of intelligent optical network as a future transmission network development direction has been recognized by the industry. As a Ciena company with a history of more than 10 years, there are many unique research results and leading technologies in this field. They have more mature ideas in the composition and technology of the new generation of intelligent optical networks. ——— Editor 1.

Dense wavelength division multiplexing (DWDM) technology provides a huge transmission capacity for communication networks, and gradually becomes the mainstream transmission technology. With the maturation of DWDM technology and the rapid growth of transmission capacity, the pressure of traditional electronic switching system is increasing, and the introduction of optical switching technology is urgent. corresponding to the 3 kinds of segmentation mul

In recent years, with the explosive growth of IP business volume, China Telecom is beginning to develop towards the next generation of Sustainable Development. Building a fiber-optic infrastructure with huge transmission capacity is the physical basis of the next generation of networks. The traditional G.652 single-mode optical fiber has been unable to meet the above-mentioned development needs of ultra-high-speed long-distance transmission networks.

A friend of the author works in China Telecom and is mainly responsible for the fiber optic business of China tietong. At a recent meeting, he told me about several failures encountered during Optical Fiber maintenance. The author selects two of the most representative introductions for readers, I hope you will learn from the article and reflect on the whole process of solving the problem. Fault 1: multiplexing segment codes caused by SDH and their ha

Hung Lian 95 Information Industry Co., Ltd. Chen Jinzhang In recent years, communication network technology has been developing rapidly with the combination of computer network technology represented by Internet, among which communication, computer, radio and television are the basis of the integration of optical communication technology more attention of the world.

Cutting-edge Cable TechnologyAdd the colored optical fiber and oil paste to the rubber sleeve tube made of high modulus plastic at the same time, the optical fiber can be moved in the casing. The cable core is made by adding a strong core along the center of different cable casings. The cable core and protective materials are added to the cable.The main features of the cable are:The rubber sleeve pipe mater

After the installation of the cable wiring system, the link transmission characteristics need to be tested, among which the main test items are the attenuation characteristics of the link, the insertion loss of the connector, the return loss and so on. The following is a brief introduction to the measurement of key physical parameters of optical cable wiring and troubleshooting and maintenance in the network. First, the key physical parameters of the

Brief history of Optical Fibers As early as 1841, Daniel Colladon of Switzerland first elaborated on the idea of transmitting a beam through a water jet. Then, through a beam in the water flow across the table, he realized light propagation in the water flow through total reflection, and created the original idea of transmitting information through optical transmission. In 1880, engineer William Wheeler lig

purchase of vrouters, vswitches, and other network devices is also very important.Internet cafes have diversified network application types and have high requirements on network bandwidth, transmission quality, and network performance. network applications must integrate advanced, multi-service, scalability, and stability, it not only meets customers' needs for simultaneous transmission of voice, video, and data over a broadband network, but also supports a variety of new business data processi

Vswitch Optical Fiber ports are divided into many types, and their functions are quite different. Here we will mainly introduce some basic knowledge about common optical fiber ports of vswitches. Cascade uses both common ports and special MDI-II ports. A straight-through cable should be used when the two ports that are cascaded are normal ports (MDI-X) ports and MDI-II ports, respectively. Cross-cable shoul
