Broadband access technology is still quite common, so I have studied the two new broadband access technologies that are currently emerging. I would like to share them with you here and hope they will be useful to you. In the past decade, two new modulation and demodulation technologies, Cable Modem and ADSL Asymmetric Digital user line, have emerged. Cable Modem implements data transmission up to 10 mbH/s on a hybrid optical fiber/coaxial network (HFC

With the continuous development of the Communication Industry, broadband access technology is constantly being innovated. Here we will introduce two new access technologies and make a detailed comparison, I believe that the access industry will develop better in the future. In the past decade, two new modulation and demodulation technologies, Cable Modem and ADSL Asymmetric Digital user line, have emerged. Cable Modem implements data transmission up to 10 mbH/s on a hybrid optical fiber/

VroInLanThere are many types of LAN interfaces to match different routes, such as the AUI port and SC port. LAN interfaces are mainly used to connect routers and local area networks. Because there are also a variety of LAN types, this determines the LAN interface types of routers. Different networks have different LAN interface types, common Ethernet interfaces include AUI, BNC and RJ-45 interfaces, as well as FDDI, ATM, optical fiber interface, these networks have the corresponding LAN interfac

connection between different networks, in order to prevent different voltages through the network cable transmission damage device. In addition, data mercury can also play a certain role in lightning protection of equipment. Rj-45 and BNC connector: RJ-45 is a network interface with twisted pair as transmission medium, which is used most frequently in 100mbps network. The BNC uses a thin coaxial cable as the transmission medium. Signal light: Aft

Ethernet (EtherNet)Originally created by Xerox, the Ethernet was developed jointly by DEC, Intel and Xerox three companies in 1980 as a standard. Ethernet is the most widely used local area network, including standard Ethernet (10Mbps), Fast Ethernet (100Mbps), Gigabit Ethernet (Mbps), and 10G Ethernet, all conforming to the IEEE802.3 Series standard specification.(1) Standard EthernetThe first Ethernet only has a 10Mbps throughput, and it uses the access control method of the CSMA/CD (carrier-l

What about the coaxial coarse cable? Coaxial thin cable?The radius of curvature of optical cable cannot be less than 30cm.The radius o

. Laying optical fiber cables should not be twisted;B. The bending radius of the optical fiber cable must be greater than 30;C. Protection steel pipes should be added to the exposed parts of optical fiber cables, and steel pipes should be firmly fixed on the walls;D. PVC should be added when the optical fiber is worn in the underground pipeline;E. Indoor cabling of optical cables should be installed in cable Trough;F. The optical fiber laying should have a margin for expansion and contraction, a

Network Interconnection device lecture Network Interconnection device Overview When connecting a computer to a computer or workstation to a server, in addition to using the connection media, you also need some intermediary devices. What are the main intermediary devices? What role does it play? This is a concern in network design and implementation. We divide commonly used connection devices into the following types: I. network transmission media interconnection Device When a network line is con

(that's, run) application programs such as a Web browser program, and e-mail client program, or an E-mai L Server program.In this book, host = End system.Hosts is somnetimes further divided into the categories: clients and servers. Note, do not assume that the server is not a terminal or host, although they provide services (search engines, mailboxes, etc.), but for the internet, they are not different from other terminals, are running the application. Servers has a large data center on th

SC type, whether in the 100base-fx, or in the 1000BASE-FX network. SC interface Core in the connector, as shown in Fig. 3, is a 100BASE-FX network SC Fiber Interface module, the right image of a 4 sc fiber optic interface of the fiber switch. There are also 2 SC fibre interfaces in the switches shown in Figure 2. 　　 　 Figure Three 　　 From Figure 2 and Figure 3, the SC interface appearance of the switch shows that it is very similar to the RJ-45 interface, but the SC interface appears to be

There are also 2 SC fibre interfaces in the switches shown in Figure 2.Figure Three From Figure 2 and Figure 3, the SC interface appearance of the switch shows that it is very similar to the RJ-45 interface, but the SC interface appears to be more flat and the gap is shallow. Mainly look

by efficient use of fiber and copper wire.The CATV is one of the representatives. In order to send TV programs, the coaxial line made of copper wire will be connected with CATV television station. Recently, Internet connections have started and applications have been made to local telephones, with more speed, more channels, and two-way communication. The coaxial axis is difficult to transmit high frequenc

achieve error-free transmission . If the channel bandwidth W or signal-to-noise ratio S/n has no upper limit (of course, the actual channel can not be such), the channel limit information transfer rate C also has no upper limit. The transmission rate of information that can be achieved on the actual channel is much lower than that of Shannon's limit transmission rate. The Nyquist theorem indicates that the rate of transmission of the code element is limited;Shannon formula gives th

broadcasting sector are currently engaged in the development of interactive video services, which, by convention, have a two-way high-bandwidth Fibre Channel, while the broadcasting department has been operating video business for a long time and has a large number of one-way High-bandwidth cable video lines. The advantage of the telecommunications sector is the existing Fibre Channel, but the Subscriber access line is still twisted, bandwidth is not enough, the solution is to use asymmetric di

The information panel is the installation equipment of the information module, and it is also the lid of the concealed square box. Here we choose the two-port information panel, one is the information mouth, one mouthful is the telephone mouth. (Figure 3) 5. Crystal Head Crystal Head Here we choose to be RJ45 crystal Head, this enables us to unify the use in the RJ45 information module and the information panel, such convenient one network cable simultaneously over the data and the telephone i

Vro interfaces are very important for network connection and routing functions. Here we will give a comprehensive explanation of vro interfaces and connection knowledge. A vro has powerful network connection and routing functions. It can be physically connected to a variety of different networks, which makes the router interface technology very complex, the more high-end router interfaces there are, the more network types it can connect. Vro ports include LAN ports, WAN ports, and configuration

A network testing instrument that combines multiple test functions to test the functions of the UTP or coaxial cable product when a twisted pair or coaxial cable site is added, moved, or changed. Whether you are an electrical contractor, a professional who pro

From figure 2 and Figure 3 right figure Switch SC interface appearance can be seen that it and RJ-45 interface is very similar, but SC interface seems more flat, the gap is lighter. Mainly look at the contact chip is what type, if it is 8 pieces of Copper shrapnel, It is the RJ-45 interface, and if it is a copper column inside is SC Fiber Interface. 3.
