cable modem coax cable

three types of connections: Male to female, male to male. Mother to mother. Each of the three connectors has crossover lines and straight lines, so there is a total of 6 connections in the same way.Question 2: How to identify the cross-serial line and direct-connect serial line?Check it with a multimeter. Suppose 2 and 2 pass. The general 3 and 3 are straight serial lines. Assume that the 2 and 3 pass, 3 and 2 general are cross-serial lines.Someone confused the outside of the mother is an insul

Internet access in China has developed very rapidly. It may not matter if many people do not know about cable modem in Internet access. After reading this article, you must have gained a lot, I hope this article will teach you more things. When cable modem uses a cable TV ne

Cable Modem is developed in recent years, mainly for CATV network data transmission. Most new cable networks now use fiber-optic coaxial hybrid (HFC) networks, and their huge bandwidth and relative economics make them attractive to cable companies and newly established telecoms companies. Because

Talking about Cable Modem broadband access technology and its maintenance when talking about Cable Modem broadband access technology and its maintenance, we need to first understand what Cable Modem?1

Production and Application of direct connection network cable and Cross network cable production and application of direct connection network cable and Cross network cable (cross line) one is the standard of the T-586A, the other is the standard of the T-568B can be directly connected to two computers (NIC-to-nic) Ord

/brownStep 6: Cut bare twisted pair wires with scissors or diagonal pliers 14mm The reason for leaving this length is to comply with EIA/TIA standards, you can refer to the relevant RJ-45 connector and twisted pair wire production standards. Finally, put each wire of the twisted pair into the pin of the RJ-45 connector in sequence, the first pin should put white orange lines, and so on Step 7: Determine the twisted pair of each line has been correctly placed a

Intersection line: One is t-586a standard on the other end is the standard of t-568b can be directly connected to two computers (network card to the network card)Ordinary network cable (straight line) at both ends are generally t-568b standardSo: Need a specially made cable, or have a spare line to change it can also be changed only a head. When making the crystal head, the other end of the 1th and 3rd to s

use of cable modem technology to realize the "triple net integration" based on the original CATV network, and to build a unified The network can carry a variety of service types, flexible user interface and wide spectrum of access bandwidth from narrowband to broadband, and take advantage of the existing equipment and unique advantages of CATV network, by providing high speed Internet access method and app

Overview Single-user connectivity test Test all types of LAN cables: UTP, STP, FTP, Coax 2, 3, and 4 pairs of twisted pair cables The following wiring faults can be detected: open circuit, short circuit, cross-connection, reverse connection, and string bypass. Wrong cabling/connection location (distance from the instrument to open or short circuit) Measurement link length Easy to use, use a single knob to select a test project Portable, long

the data broadcast system. After painstaking research, our company has developed a stable and reliable system, which is equivalent to the latest foreign products, some indicators are superior to those of the overseas products. Our system can adopt completely localized front-end devices and localized data receiving cards, fully complying with the relevant DVB standards. The experiments that can be run without any modifications on the existing cable TV

the connector is pulled. When using this protective sleeve, you need to put this rubber sleeve on the twisted pair cable before the crimping RJ-45 connector,.Step 8: Repeat steps 2 through 7 before creating the RJ-45 connector for the other end. Because the workstation is directly connected to the hub, the pin connection of the RJ-45 connector at the other end is exactly the same. After the completion of the connection lines at both ends of the RJ-45

monitoring stations. It is the center for data collection and processing, with controller servers, clients, and workstations) vro, Hub/switch hub, network adapter, MODEM, printer, and related software. PMC generally adopts the primary standby mode. The monitoring station is responsible for remote automatic monitoring of optical cable lines, and tracking changes in optical fiber transmission loss. The monit

is directly connected to the hub, the pin connection of the RJ-45 connector at the other end is exactly the same. After the completion of the connection lines at both ends of the RJ-45 connector both pin and color are complete ~ The connection method is applicable to the connection between the ADSL modem and the computer Nic.The direct connection network cable is used for the connection between the ADSL

Crossover network cable for ADSL modem and hub Hub connection (and modem design is related, not all of this), hub and hub not through the connection between the Cascade, and two of computers directly through the network card interconnection. The production method and the above basically the same, but the online order is not like 568B, using the 1-3,2-6 Exchange M

The cable system is designed and constructed for the convenience of the landlord, but the landlord and the facility manager usually have no knowledge or measure of the interior of the room to ensure the proper design and installation of the cable system. General contractors and construction managers are generally not experts on telecommunication cables, nor can they take into account the best interests of t

interface connection can be. 2, telephone line access to the household network Telephone line entrance is the most we have seen before, there are still a large number of users to use this way of surfing the Internet, the connection is actually the same as the optical fiber entrance, the schematic diagram below. Schematic diagram of wire connecting to the telephone line in the household router The vast majority of households used to use telephone lines dial-up Internet, the use o

XP system cannot connect to the solution that prompts "network cable to be unplugged" Specifically as follows: 1, again check whether the network cable is not plugged, network cable has no problems. 2, check the Internet equipment, the modem has no power, the modem

construction personnel must ensure that the cables can support applications. For example, a shared receiving cable MODEM or DSL line allows multiple family members to access the Internet at the same time. However, if the cable is installed carelessly, performance may degrade. Certification testing tools, however, are more than $6000 in complexity, difficulty in

When we use computers for work, study and recreation, what are the most feared things to encounter? I think there are a lot of users will say that the network has broken the problem, that is, the computer desktop in the lower right corner of the local connection shows the network cable did not plug the good tips, why this situation? A lot of XP SP3 system users will always inexplicably encounter this situation, but their network

Comparison of IP transmission technology in cable TV networks Abstract: IP transmission technology in cable TV networks includes three forms: IP over ATM, IP over SDH, and IP over WDM, this article introduces and compares the three IP Address Transmission Technologies in detail. Key words: IP technology, cable TV network, IP over ATM, IP over SDH, IP over WD
