China Telecom Shanghai (hereinafter referred to as Shanghai Telecom) disclosed its goal after broadband acceleration when it announced that it would start its fifth broadband acceleration this year, it is planned that the coverage of optical networks will increase by 1 million to 7.8 million, and the number of optical network users will increase by 1 million to 3.6 million. At the same time, Shanghai Teleco

method of optical fiber access network. "Large Capacity, small bureau" means that the number of users covered by the OLT increases, and new requirements are raised for the features of the OLT system capacity, backboard bandwidth, port density, and coverage distance, at present, there are large-capacity OLT devices in the industry, including 960G switching capacity, 40G bus, 8 PON ports, 10 Gbps uplink ports, and 60KM long-distance PON technology. Mul

-to-manage, low-investment, and high-income Internet cafe network is extremely important. selecting an appropriate network access method is the key to achieving this, the 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

, its unique design in many aspects can satisfy enterprise users who have special requirements on routers. It is a rare high-quality product in the router market. General evaluation:In enterprise network usage, stability is crucial. It can be said that "stability prevails over everything". Therefore, when purchasing a vro, the stability of the vro should be considered first, at the same time, reliability, security, and ease of use should also be considered. Of course, the price cannot be ignored

government buildings. In the initial stage, we will first provide broadband Internet services for users. In the later stage, we will need to carry out IPTV, VoIP and other value-added data services. This plan mainly takes into account the access of households, and the commercial, school, and institution will be adjusted based on actual conditions in the future. This network can provide sufficient bandwidth for high-quality data access services and IP

As one of the most important devices in the storage system, fiber channel switches are widely used. I believe many consumers do not know how to buy them, the following is a detailed analysis of the selection of fiber channel switches. The fiber channel network built through the fiber channel (FC) switch is called Fabri

Fiber-optic access broadband is faster and more stable than ADSL transmission, so many friends now choose the fiber-optic access when they install broadband. But when I installed the FTTB dialer under Windows XP, I encountered a problem: 　　 Cause of failure In Windows XP, follow the steps under Windows 98 to inst

, thousands of households are connected to catv TV stations on the same axis of copper wires. Recently, Internet connections have been started and used in local telephones. The higher the speed, the more channels, and two-way communication has been started. It is difficult to transmit high-frequency electrical signals from the same axis over a long distance. Therefore, to increase the communication distance, a large number of amplifiers must be used, and the cost will also increase. If

I. Overview As information technology is increasingly developed, data transmission is extremely important, in order to meet the needs of high-speed local computer networks, conference television, video-on-demand applications, and other applications, it is becoming an important topic of material science to seek information transmission media with a higher speed and Information Transmission volume. At present, in the process of information transmission, we can use copper cables with metal as media

The urgent needs for high-speed data services and the future needs for video services provide unprecedented opportunities for broadband access, and various broadband access technologies are emerging. The ATM-based PON combines the capabilities that ATM is suitable for providing comprehensive broadband services. The upstream and downstream communication bandwidths

At present, the optical fiber access network has been widely used in urban construction. So I have studied the principles and precautions for the construction of the urban optical fiber access network. I would like to share with you here and hope it will be useful to you. With the increasingly fierce competition in the communication industry, business development is also becoming more and more diversified,

sun and rain, the water is split from the thin area of the outer skin, make the external conductor metal layer or metal mesh) corrosion. When the fault is checked with A multimeter, If the measured loop resistance is much higher than the original cable loop value, it proves that the outer conductor is seriously corroded. If the measured loop value is infinite, it indicates that the outer conductor is broken after corrosion. In short, there are many methods for detecting coaxial cables. As long

After reviewing the network development process, we will all feel that the network is evolving with each passing day, and network applications have been updated and upgraded almost every several years, the continuous development of network applications puts forward higher bandwidth and other related performance requirements to people. With the popularization and application of gigabit and 10-Gigabit networks, in our traditional cabling system, currently, copper cable systems can only be used for

The wireless broadband technology has been favored by many people. Its excellent performance has become a leader in wireless technology. Even so, it also has many drawbacks. So what is the bottleneck of its development? Let's take a look at the problems in the development of wireless broadband access products. As a new access technology, broadband wireless access
