ends of a line must be made using the same standard. It is best to use only one standard network cable on the same HUB or switch. (2) When only two computers do not use hubs or switches, The 586A standard is adopted for one end of the line and 586B standard is adopted for the other end. Because the Ports 1 and 2 of the NIC are used to send data, while the ports 3 and 6 are used as the receiving data pins. The two different standards correspond to values 1, 2, 3, and 6. (3) No matter how close t

wires and the cost is significantly lower than WiMAX, but over time, once the development of WiMAX significantly reduces the cost, DSL technology will be threatened to be eliminated by WiMAX technology. Ii. WiMAX and Cable Cable Modem technology can be divided into two-way symmetric Transmission and non-symmetric Transmission. The symmetric transmission rate is 2 Mbit/s ~ 4 Mbit/s, up to 10 Mbit/s. The downlink rate of asymmetric transmission is 51 Mbit/s, and the uplink rate is 500 Kbit/s ~ 31

display screen. However, if you cannot transmit the video content to the display screen, everything is blank! In the real world, buildings were built at least in the 1980s S, and are generally not designed for the cabling requirements of the Information Age. Cabling slots and channels are generally crowded. Cables required to support high-definition videos (VGA or XGA at least) (for example, coaxial cables connected at the top of a 5 BNC connector or

To build a new broadband community, we have many options, including the Ethernet access scheme, ADSL access scheme, Cable Modem and hfc-network scheme, and optical fiber access scheme. How should we choose these access solutions? Different solutions vary in application scenarios. Let's take a look at the features of several access solutions. High-speed Ethernet solution In the broadband access technology, Ethernet has become the most widely used local network transmission method. It uses baseba

Different access network solutions have different application fields, and different technologies are used at the same time. Various technical solutions have their own advantages and disadvantages. How to choose a suitable solution, users need to think carefully. To build a new broadband community, we have a lot of options, including Ethernet access network, ADSL access network, Cable Modem, and HFC network, and optical fiber access network. How should we choose these access solutions? Different

I. Optical Fiber1. OverviewThe optical fiber is similar to the coaxial cable, but there is no mesh shielding layer. The center is the glass core of light transmission. In multimode optical fiber, the core diameter is 15mm ~ 50mm, roughly equivalent to the hair width of a person. The diameter of the Single-Mode Optical Fiber Core is 8mm ~ 10mm. The outside of the core is surrounded by a glass envelope with a lower refractive index than the core to keep

cable splitters that provide thoughtful cable protection during installation. The instructions In the box can provide various services or clear identifiers for each room. The box also provides connection ports for various types of distribution frames, and the connections for various distribution frames are easy to install and maintain. Therefore, after the In HouseTM series are packed on the cable end, all types of distribution frames with clear identifiers are displayed, and the cables are hid

With the extensive use of computers, network and Integrated Wiring have naturally become a hot topic. Correct design and layout of a network system not only improves the speed and reliability of communication, but also greatly improves the work efficiency; in cabling, the carrier for signal transmission-transmission media must be used. In a complete and stable network environment, the selection and correct utilization of transmission media are required, it is the basis for the long-term stabilit

ADSL technology, which can economically transmit several megabits of information per second on the twisted pair copper line. It supports traditional voice services, it also supports data-Oriented Internet access. After the local ADSL Access multiplexing device multiplexing data traffic, it selects a route to the group network to transmit the voice traffic to the PSTN, ISDN, or other group networks. Cable modem can provide high-speed data communication in a fiber-optic

Complies with ISO/IEC11801, TIA/EIA568A or 568B standards. Cables for information points that provide online services are allocated to the six data modules of the functional component. Then, use the network jumper to connect the switch ports of the Self-small switch or Broadband Router to the RJ45 ports on the m

The residential network is growing at a rapid rate, which is largely driven by the need to share printers or connect to the Internet with multiple home PC machines. Residential networks and video applications are also closely related, such as televisions, video recorders, DVDs, security cameras, baby monitors, and home audio and video systems. Families with residential networks can enjoy higher returns and can easily add or modify existing applications. However, it is more challenging to create

rate of 622.08 Mb/s ). This speed is selected to be compatible with SONET, which is the frame separation standard used for optical fiber lines in the telephone system. Based on T344.736Mb/s) and FDDI100Mb/s), the ATM has also appeared.ATM Transmission Media are often optical fiber cables, but coaxial cables within M or five twisted pair wires are also possible. The optical fiber can reach several kilometers. Each link is located between a computer an

testing working group is composed of technical personnel of the cabling company and the company to conduct on-going tests on all information points. For example, five types of tests are spot-checked according to 20% of all information points. After acceptance, technical personnel are responsible for routine maintenance and management of the network. Testing Instruments and testing standards Before testing, we need to select appropriate testing instruments and testing standards. Generally, we us

used on the telephone); RJ45 head according to the order of the line is divided into two kinds, one is white orange, orange, white green, blue, white blue, green, white Brown, Brown, and the other is white green, green, white orange, blue, white blue, orange, white brown, brown So there are two kinds of lines that use RJ45 connectors: (12345678 corresponds to 12345678), crossover line (12345678 corresponds to 36145278). Media and connected devices Interconnection devices for communication

electrical signal, and then converts the signal into a light signal to use the new light wave. Because digital signals can be corrected and regenerated, signal attenuation and distortion will not occur due to multiple conversions, which can ensure signal transmission quality and provide unlimited relay. Optical Relay: directly amplifying the attenuation optical signal sent from a distance to continue forward transmission. This is the simplest method, and the signal does not need to be convert

locations, the transmission rate will rapidly decline, and frequent problems requiring repeated transmission. If you must deploy a network cable near a wire, make sure that the network cable passes vertically rather than in parallel. Once upon a time, at the end of 1990s, the author encountered that the newly installed coaxial cable could not work normally. This line was originally responsible for connecting two very close buildings, after various tr

Currently, available broadband technologies include T-1, DSL and Ethernet-based man access. High cost of T-1 services, DSL is not available anywhere, especially if the user's location is too far away from the center, and the use of Metro Ethernet is limited to big cities. Now, a new technology allows enterprises to obtain dedicated, IP-based broadband connections through standard coaxial cable lines. Generally, cable networks have some limitations tha

transmitted to the user in the form of optical fiber, then, the optical terminal is converted into a pair of coaxial (BNC). If the wide-area port of the user's router is in the serial port format (for example, V.35), in order to convert the BNC to the serial port, the Protocol converter is required. That is to say, the input of the Protocol converter is a coaxial cable, while the output is a serial port. T

determines whether to forward the packet by judging whether the destination address and source address are in the same network segment, generally, a small office network device has only two interfaces, one connecting to the Internet and the other connecting to a LAN Hub or switch. Therefore, it is generally set to a default route, as long as it is not an intranet segment, all Forwarding is performed ｡ In the Wan project, the Protocol converter is a telecommunications terminal device used at bot
