There are many things worth learning about the optical fiber access network. Here we will mainly introduce notes on emerging technologies of optical fiber access networks. At present, the world's optical fiber copper withdrawal has become a trend in the Construction of optical fiber access networks. The FTTx Access Net

Over the past decade, the intensity of land use in the Pearl River Delta region has continued to rise. In 2013, Dongguan mingpu optical magnetic Co., Ltd. drew a piece of land of up to 50000 m² yuan in Dongguan stone platoon, and resolutely planned an independent development base. When all the bases are built, together with the original factory production, the annual output of mingpu will reach 2 billion. In the face of rising land intensity, declinin

In this age when laptops are already popular in conference rooms, business people take notebooks to demonstrate PowerPoint and electronic meeting minutes, and when laptops are already popular in classrooms, students even use notebooks to read books for open exams. With the notebook computer is becoming an integral part of people's lives, the new problem comes, the blind pursuit of price-performance is caused by the body weight unscrupulous in the shoulders of people, that is, "pole effect." Peo

Fiber-optic Ethernet switches are still quite common. So I have studied the comprehensive performance of various types of fiber-optic Ethernet switches. I would like to share with you here and hope they will be useful to you. Fiber-optic Ethernet technology is the integration and development of the two mainstream communication technologies, namely, Ethernet and optical network. It integrates the advantages of Ethernet and

As the application of the GMPLS/ASON technology in intelligent optical networks began to scale, we began to realize that the construction and development of transmission networks not only included the transmission hardware technology, the unified network management and control of the transmission network are also two difficulties for network construction and equipment technology development. GMPLS/ASON Control Plane extends from SDH to WDM and CE, and

The port of the core switch is mainly of the optical fiber type, but the price of the optical fiber port of the switch is very expensive. You must note that the optical fiber port of the switch is not stacked and can only be used for Cascade. Analyzes the connection methods and basic types of the optical fiber ports of

Along with the social progress and development, as well as people's growing material and cultural needs, communication to large capacity, long-distance direction of development has been an inevitable trend of development. Since the light wave has a very high frequency (about 300 million MHz), that is, it has a very high bandwidth to accommodate huge communication information, so the use of optical waves as a carrier for communication has been the goal

Computer startup in the "My Computer" to find the optical drive icon, naturally is not used, this fault is generally the optical drive driver is missing or damaged, optical drive interface bad, optical drive data line damage, optical drive jumper error, and so on.This failur

Photoelectric Mouse is a kind of hardware device that detects the displacement of mouse, converts the displacement signal into electric pulse signal, and then controls the movement of the cursor arrow on the screen by program processing and transformation. The photoelectric sensor of the photoelectric mouse replaces the traditional rolling ball. This type of sensor needs to be used in conjunction with a specially designed pad with a striped or dotted pattern. Mouse Research report shows:

Virtual optical drive Daemon tools using method Although there are many kinds of virtual optical drive software, but they use the same method, first of all, the current mainstream elf virtual optical drive (Daemon Tools Lite) as an example to give you a brief introduction: First, Software Installation First download daemon Tools Lite version, Lite is a free ve

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

Any professional who has done network troubleshooting knows this is a complex process. Here are some of the most common fiber failures and possible factors for these failures, which will help users to have a base guess on network failures. Fiber breakage is usually caused by physical extrusion or excessive bending of the external force; Insufficient transmission power; Optical fiber laying distance too long may cause signal loss; damage to the co

how the Win7 system uses the Daemon tools virtual optical drive The specific methods are as follows: 1, the first Internet search and Download Wizard Virtual optical Drive (Daemon Tools Lite) 4.46.1 official Chinese version; 2, because the download of the program is a compressed package, so first of all to be decompressed. Then run Setup directly to install the wizard virtual CD-ROM into the

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

1. Troubleshoot optical drive driver Windows operating bears automatically recognize the optical drive and install the driver for the optical drive, and you need to load the driver for the CD drive when you use the DOS operating system, and check the CD drive and other devices for conflicting issues. 2, troubleshoot the opt
