Maybe many people do not have a special understanding of the man optical cable line. Next we will introduce in detail the overall design and technical application of the man optical cable line. 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 topol

Broadband optical fiber access network is a common access method, but its implementation is complicated. We need to make full preparations in the early stage, A reasonable plan can be designed to avoid problems in subsequent work. 1. Principles of broadband optical fiber Access Network1) Guiding Ideology of networkingMeet the rapidly growing business needs and support various application systems. It provide

In various technical means to achieve broadband access, the optical fiber access network is the most suitable for future development solutions, especially the ATM Passive Optical Network (ATM-PON) it is almost an economical and effective way to integrate broadband access. Outside China, china Southern Bell, France Telecom, British Telecom, CNET, Japan NTT, Germany Telecom, KPN, SwissCom, SBC, Telecom Italia

Absrtact: The development of telecommunication service needs new and more intelligent Optical Network support, Nortel Network Company's Optera series product has the main performance of new optical network, conforms to ITU-T's automatic switched Optical network standard--G.ASTN. Firstly, the structure of the automatic Switched

Failure phenomenon: When the optical drive problems, the general performance of the optical drive is flashing, can not read disk or read disk performance decline; When the optical drive reads the disk, the blue screen crashes or displays "Unable to access the disc, the device is not ready" and so on. The following, the author according to the CD-ROM installation

, large enterprises, government agencies, institutions, and other branches have their own local area network, and how reliable and secure interconnection between the LAN, forming the national and even the global group user intranet, to achieve office networking, improve efficiency, This also requires network operators to provide good quality and price solutions. In the connection of the special line interconnection, at present, the domestic 2M below the use of Ddn and FR, with the increase in

advent of optical fiber communication technology, the large potential bandwidth capacity of nearly 30THz has brought the flourishing opportunity to the communication field, especially since the information superhighway was put forward, the optical technology began to permeate the whole communication network, and the optical fiber communication has the trend of a

The rapid development of optical network technology has brought people completely transparent access capabilities and unlimited bandwidth resources. However, in order to truly take advantage of the advantages of light technology, service providers also need to optimize and integrate IP services to ultimately build a light Internet that suits the future business development needs. This is the initial reason for the generation of IP optimized

1. What is GBIC? GBIC is short for Giga Bitrate Interface Converter. It is an Interface device that converts Gigabit electrical signals into optical signals. GBIC is designed for hot swapping. GBICIs an Interchangeable product that complies with international standards. The gigabit switches designed with GBIC interfaces share a large market share due to flexible exchange.2. What is SFP? SFP is short for small form pluggable. It can be understood as an

The optical fiber access network is worth learning a lot. Here we mainly introduce the current situation and development trend of the access network in China's communication industry, including the TMN status of the access network and the remote network management technology of the optical fiber access network, for your reference only. I. Current Situation and Development Trend of access networks in China's

What's going on with the automatic eject of the optical drive? Problem Description: Netizens just bought a new computer, found that the optical drive is always bouncing out of their own and automatically bounce in. have been so repeatedly, in the end what is the fault? Consult our computer engineer! CD-ROM automatic eject explanation: Under normal circumstances, when the

After reasonable management, two kinds of distortion factors (dispersion and self phase modulation) in optical fiber can cancel each other, so that the optical soliton can play its role. The color closing causes the pulse signal containing a group of wavelengths to diverge gradually with the increase of the transmission distance. Self-phase modulation (SPM) spreads the spectrum of light pulses horizontally.

1. photoelectric signal conversion method For a long time, people have been using copper wires to transmit sound and information. However, more and more fiber cables have been used recently. Due to cost problems, we cannot replace all copper wires with optical fiber cables at once. However, to convert some cables into optical signals, the most important thing is to convert the electrical signals into

The Next Generation Network (NGN) is a hot topic in communication industry at present. As for the next generation optical network, taking SoftSwitch technology as the core, using high-capacity High density wavelength division system, large capacity optical switch with automatic configuration function, a new generation of optical routers, all kinds of low-end

Notebook Optical drive failure problem resolution, notebook optical drive The most common fault is mechanical failure, the second is the circuit fault, and the fault in the circuit caused by improper adjustment of the fault is much more than the fault of the components, so in the dismantling or maintenance of optical drive equipment, do not casually adjust the in

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 impurities and oh-, so that the light in the transmis
