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

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

With the continuous development of the Internet, the rapid growth of voice, data and multimedia services poses higher requirements for the transmission network's transmission bandwidth, interface methods and operation and maintenance. With the development of 40g synchronous transmission technology, wavelength division multiplexing technology, and ultra-long optical transmission technology, optical transmiss

The rapid development of the Internet has led to the further prosperity of the Internet bar industry. The access methods of Internet cafes are also different, and network networking solutions are also varied. At present, the international Internet access solutions include optical fiber, ADSL, satellite broadband access and other broadband access and DDN, ISDN and other narrowband access. Among the many Internet access methods, Internet cafe operators

The following describes FTTH access technical standards and deployment solutions, including how FTTH is connected to your network. As copper prices keep rising and the cost of optical cables keep decreasing, fiber-to-household (FTTH) services that provide bandwidth much higher than metal wire access are becoming the focus of ISP (broadband operator) promotion this year, in the near future, high-speed broadband will no longer be a dream for ordinary co

There are many broadband Internet access methods. For enterprises, ADSL and optical fiber are currently popular. The full name of ADSL is an asymmetric digital user line. It is a popular broadband Internet access method and a technology that provides broadband data services through copper telephone lines. Optical fiber is short for optical fiber.

On the one hand, the performance of the network of enterprises more and more high, on the other hand, the cost of fiber also more and more It is now becoming more common to achieve high bandwidth through optical fibers, such as connecting between the two offices through fiber optics, previously connected directly through a wire. Fiber optics for enterprises may not be luxuries, but necessities. Although the light can provide a lot of bandwidth, but

The common failure of the optical drive besides the decline in the ability of the bald-headed aging, there are some unusual mechanical faults. I have recently encountered an example. An optical drive, the ability to read the disc is good, has not been repaired. Recently press out the Cangjian, feel the CD-ROM slow reaction, tray eject slowly, also so into the warehouse. After a period of time, the fault a

The most basic switching unit in optical burst switching technology is burst data. Meanwhile, BCP and burst data in OBS are separated on the physical channel, and each control group corresponds to a burst data. With the rapid growth of IP services around the world, the demand for transmission network bandwidth and switch system capacity is increasing at an unprecedented rate. Currently, DWDM technology is used in the

Cable construction is roughly divided into the following steps: Preparation → route engineering → Cable laying → cable connection → engineering acceptance. 1. Preparatory work (1). Check the design materials, raw materials, construction tools and equipment are complete. (2). To establish a high-quality construction team. This is important because optical fiber construction is more stringent than cable construction requirements, any construction of

With the gradual application of smart optical network ASON, the transmission network will gradually increase the number of intelligent network elements. As operators have invested heavily in the traditional SDH network, in order to protect the original investment and realize the smooth evolution of the traditional optical transmission network to ASON, the intelligent network and traditional devices will coe

First, the outer skin: Indoor optical cables are generally used polyethylene or flame-retardant polyethylene vinyl, the appearance should be smooth, bright, flexible, easy to peel. Poor quality of the optical cable skin finish is not good, easy and inside the tight sleeve, aramid adhesion. Outdoor fiber optic cable PE sheath should use high-quality black polyethylene, into the cable after the skin smooth,

Based on years of experience in design and construction, the author summarizes a set of practical detection methods and shares them with colleagues. Check and install After the optical cable is connected and the connector is installed, the continuity check of the optical fiber must be carried out, and all the optical fiber cables must be tested. Therefore, the pe
