Twisted pair cable can be divided into unshielded twisted pair (UTP) and shielded twisted pair (STP).
Shielded twisted-pair cable is wrapped by aluminum-platinum outer layer to reduce radiation, but does not completely eliminate radiation, shielded twisted-pair cable is relatively expensive, installation is more difficult than unshielded twisted-pair cable.
Non-shielded twisted-pair cable has the following advantages: no shielded jacket, small diameter, saving the space occupied; light weight, easy to bend, easy to install; will minimize or eliminate the near-end crosstalk; flame retardant; independence and flexibility, suitable for structured integrated wiring.
Twisted pair of common models are as follows:
One type of wire (CAT1): mainly used for transmission of voice (one type of standard is mainly used for telephone cables before the early eighties), different from data transmission.
Category 2 cable (CAT2): Transmission frequency of 1MHZ, used for voice transmission and data transmission at a maximum rate of 4Mbps, commonly found in older token networks using the 4MBPS specification of the token passing protocol.
Category 3 cable (CAT3): Transmission frequency of 16MHz, used for voice transmission and data transmission at a maximum transmission rate of 10Mbps is mainly used for 10BASE--T, the cable specified in the ANSI and EIA/TIA568 standards.
Category 4 cable (CAT4): transmits at 20MHz for voice transmission and data transmission at a maximum rate of 16Mbps is used primarily for token-based LANs and 10BASE-T/100BASE-T.
Category 5 cable (CAT5): transmits at 100MHz for voice transmission and data transmission at a maximum rate of 100Mbps for data transmission, mainly used for 100BASE-T and 10BASE-T networks. This is the most commonly used Ethernet cable, which has increased winding density and a high-quality insulation.
Ultra Category 5 cable (CAT5e): Transmits at 100MHz and is mainly used for Gigabit Ethernet (1000Mbps). With low attenuation, less crosstalk, and has a higher attenuation to crosstalk ratio (ACR) and signal-to-noise ratio (StructuralReturnLoss), smaller time-delay difference, performance has been greatly improved.
Category 6 cable (CAT6): Transmission frequency of 250MHz, best suited for applications with transmission rates higher than 1Gbps, mainly for Gigabit Ethernet (1000Mbps). Category 6 twisted-pair cable is somewhat different from Category 5 or Ultra Category 5 twisted-pair cable in both appearance and structure. Not only is there an insulated cross-bone added to place the four pairs of twisted-pair wires in each of the four grooves of the cross-bone, but the cable is also thicker in diameter.
Super Category 6 or 6A (CAT6A): the transmission frequency is 200 to 250MHz, the maximum transmission speed can also reach 1000Mbps, mainly used in gigabit networks. Super Category 6 cable is an improved version of Category 6 cable, also an unshielded twisted-pair cable specified in ANSI/EIA/TIA-568B.2 and ISO Category 6/Class E standards, with major improvements in crosstalk, attenuation and signal-to-noise ratio.
Category 7 cable (CAT7): Transmission frequency up to at least 500MHz, transmission rate up to 10Gbps, it is mainly to adapt to the application and development of 10 Gigabit Ethernet technology. This cable is the latest type of shielded twisted pair cable in the ISO Class 7/Class F standard.

Ultra Category 5 and Category 6 network cable connection to use and is not different, only the use of the occasions and the cost of different.
Super Category 5 cable is identified as "CAT5E", with a bandwidth of 155M, is currently the mainstream product;
Category 6 cable is identified as "CAT6", with a bandwidth of 250M, Category 6 unshielded twisted pair cable can be very good to support Gigabit Ethernet and realize 100m transmission distance. Category 6 cabling systems are widely used for server room cabling and horizontal cabling that retains the ability to be upgraded to Gigabit Ethernet. Category 6 unshielded twisted-pair cable, although more expensive, is slowly becoming the new favorite of integrated cabling because of its very good compatibility with Super Category 5 cabling systems and its ability to support 1000Base-T very well.
If you consider the future application needs of the network, the theory should be installed the most advanced cabling products, because the installation of cables is often difficult to re-update the replacement, basically, a cabling system should be applied for at least 10 years as a standard, to be able to support the performance of 4 to 5 generations of network equipment updates, if the future of the network equipment needs better cables in order to improve the speed of data. Then, the use of Category 6 cable instead of Category 5 cable is unavoidable, but these cables are very expensive to reorganize the project, so even though the price of Category 6 products is slightly more expensive relative to Category 5 products, but in order to reduce the problem of network upgrades in the future, Category 6 products are still worth considering.
Types of Coaxial Cable CoaxialCable network cable kitchen organizer na kitchen organizer Coaxial cable (CoaxialCable) is a cable that has two concentric conductors, and the conductors and shielding are **** with the same axis. The most common coaxial cable consists of copper wire conductors isolated by insulating material, on the outside of the inner layer of insulating material is another layer of ring conductors and their insulators, and then the whole cable is wrapped by a jacket made of polyvinyl chloride or Teflon material.
OpticalFiberCableTypes of network cablesKitchen organizerKitchen organizerOptical cables (opticalfibercable) are manufactured to meet optical, mechanical, or environmental performance specifications, it is the use of one or more optical fibers placed in a cladding sheath as a transmission medium and can be used individually or in groups of communication cable assemblies. Fiber optic cable is a certain number of optical fibers in accordance with a certain way to form the core of the cable, the outer jacket, some also covered with an outer jacket, to achieve optical signal transmission of a communication line.
Part2: Mastering the network purchase method to ensure the quality of the Internet 1 network cable material which is good? Pure copper copper wire is the best and highest quality network cable wire, suitable for POE power supply, small resistance to avoid the loss of electricity in the transmission process. Aluminum wire quality is second to copper wire, only suitable for short distance POE power supply, resistance than copper wire, home or small office terminals, switch lines can be.
Copper clad aluminum wire such as aluminum wire outside the plating of a layer of copper, due to the skin effect, the conductive ability of aluminum wire has a certain degree of enhancement, resistance is larger, only suitable for short-distance POE power supply.
Source website: copper clad iron wire such wire in the iron wire outside the plating of a layer of copper, because of the skin effect, the conductive ability of the iron wire has a certain degree of enhancement, resistance is larger, not suitable for POE power supply. Source Site: Iron core wire iron core wire such wire resistance is large, not suitable for POE power supply, only suitable for short distance transmission and the network speed requirements are not high. Source site: hybrid wire hybrid wire inside part of the wire using copper, part of the wire using aluminum, only suitable for short-distance use, can be used for POE power supply, the crystal head connection method is strict. 2 network cable which is good network cable purchase method to identify the identification of the identification of the three types of cable is "CAT3", the identification of the five types of cable is "CAT5". "CAT5", the identification of ultra-five cable is "CAT5E", the identification of category six cable is "CAT6". Feel with your hands high-quality network cable generally use copper wire as the core of the wire, relatively soft, low-quality wire added other metal elements, relatively hard, not easy to bend, easy to break the line in use. With a knife to cut off the plastic skin to reveal the core line, white core line is flower white, fake goods are usually pure white or flower color is not obvious. Good netting winding density is moderate, the direction is counterclockwise. Burning with fire with 35 ° C to 40 ° C high-temperature test, the genuine network cable outside the rubber skin will not become soft, the real network cable outside the rubber has a flame retardant, while some of the fake does not have a flame retardant.
Part3: Difference Between Switch and CatDifference Between Switch and Router1Difference Between Switch and CatKitchen OrganizerKitchen OrganizerThe modem is affectionately known as a "cat" based on the harmonic sound of Modem. The cat has at least two ports, one for the telephone line and one for the network cable, and its function is to convert the signals from the telephone line into digital signals and pass them to the computer, and then convert the digital signals from the computer into telephone signals and transmit them out, so as to realize that the computer can access the Internet through it and the telephone line.
Kitchen storage na kitchen storage switch: you can make the connection switch of multiple computers to form a local area network to achieve simultaneous Internet access function, and access to the switch for any two network nodes to provide exclusive access to the electrical signal path. That is, 100M bandwidth, no matter how many computers are connected, theoretically each computer's bandwidth reaches 100M.
2 switch and router difference kitchen organizer kitchen organizer switch is a network cable to access the Internet, but everyone access to the Internet is dialing separately, each using their own broadband, everyone access to the Internet has no impact. And the router than the switch more than a virtual dialing function, through the same router Internet access to the computer is **** with a broadband account, everyone online to affect each other.
Switches work at the trunk layer, and switches are addressed according to MAC addresses. Routers work at the network layer and address based on IP addresses, and routers can handle the TCP/IP protocol while switches can't.
The switch can enable multiple computers connected to it to form a local area network (LAN), and if there is a proxy server, it can also realize simultaneous Internet access and all the computers on the LAN are *** enjoying its bandwidth rate. But the switch does not have the router's function of automatically recognizing the address to which the packet is sent and arrives. Routers can automatically recognize the address of packets sent and received, routers are equivalent to the police on the road, responsible for traffic guidance and directions.
To give a few examples, the router is a small post office, an address (IP), responsible for a place to send and receive (personal computer, a server, so your home to the Internet to this thing), the switch is a large postal center in the province, responsible for an address to the various small places in the contact. Simply put, the router is in charge of entering the network, the switch is only in charge of distribution, the router is for you to find a way to let you go online, the switch is only responsible for opening the door, the switch above the router you can not get on the Internet. Routers provide firewall services. Routers only forward address-specific packets and do not transmit packet transmissions that do not support routing protocols and unknown destination network packet transmissions, thus preventing broadcast storms.
Part4: how to connect the network cable network cable connection diagram 1 home network and office network difference between the kitchen organizer kitchen organizer kitchen organizer most of the use of twisted-pair cable in the family (that is, the general network cable), generally divided into T568A and T568B two kinds of wiring order, the information module end of the access method is divided into the T568A module and the T568B module two kinds of ways, two kinds of termination methods corresponding to the order of the wiring is as follows
T586A mode ① white green ② green ③ white orange ④ blue ⑤ white blue ⑥ orange ⑦ white brown ⑧ brown;
T586B mode ① white orange ② orange ③ white green ④ blue ⑤ white blue ⑥ green ⑦ white brown ⑧ brown.
2 home network cable wiring advice kitchen organizer na kitchen organizer in the network wiring before, first of all, you should understand their own living room environment and the use of each room, what place can be trenching buried line, what place can not? At the same time to understand the family's network needs, what place to surf the Internet? What place to watch TV? You should have a number in your own mind. According to their own vision to draw a design sketch, and then according to the room's power distribution box, cable TV inlet and telephone line, network cable into the account location, to determine the location of the distribution box and splitter. The general power distribution box should not be easily moved; the distribution box for telephone line and network line should be selected in a place that does not affect the aesthetics and is easy to operate, taking into account the router and switch to be put in, so it should be designed as a larger distribution box; cable TV is designed in the inlet to be able to place two TV distributors in a box. It is recommended that we use parallel wiring, and telephone lines and network lines were used 4-core and 8-core (Category 5) line, for convenience, telephone lines and network lines through the same PVC pipe (theoretically, telephone lines and network lines should be separate wiring, spacing of 10cm to avoid mutual interference), taking into account the family telephone and Internet use at the same time a very short time, will not cause major interference. If there are multiple computers to access the Internet at the same time, just add a broadband router or switch at the main wiring.
3 office network wiring recommendations kitchen organizer kitchen organizer 1, comprehensive: office wiring needs to meet a variety of different analog or digital signal transmission needs, all the language, data, graphics, monitoring equipment wiring combined in a standard wiring system, equipment and information outlets only a standard connecting cable through the standard interfaces to connect them can be.
2, reliability: office cabling system using products must be certified by international organizations, cabling system design, installation, testing to ANSIEIA/TIA568A and GB/T50311-200 for the cabling standards, follow the domestic cabling specifications and test specifications.
3, flexibility: each office in the end how many information points, office cabling not only to meet the user's current needs, but also in line with the user's expectations for the future of the information system unity; and data, voice twisted-pair cabling should be interchangeable, constituting a complete set of cabling system.
4, reasonableness: the office of strong and weak wiring direction should be reasonable with each other, do not interfere, and to beautiful appearance; users also use the computer's power supply, telephone, network cable should be easy to operate, easy to operate and maintain in the future.
5, wired and wireless complementary: according to the building's specific architectural environment and office requirements, long-term or temporary use of the network and so on, to decide whether to use wired wiring or wireless; in general, it is a combination of wired and wireless, to play their respective strengths, to achieve the purpose of our office online.
4 network cable outlet connection kitchen organizer na kitchen organizer with a wire stripping tool or crimping pliers cutter in about 10 centimeters long from the head of the wire will be twisted pair of outer wrapping stripped, revealing four pairs of twisted pair of wires. Begin wire stripping, do not detach the pairs until the corresponding pairs are pre-pressed into the striking posts. Follow the color coding indicated on the information module to select our preferred wire pattern (it is best to use only one wire pattern consistently in a wiring system, otherwise it is difficult to check if the wiring is messed up and the network does not go through). After all the wires are pressed into each slot, use a tool to press the module and the wire, press down hard to snap the wire inside the module, and cut off the excess first. It is the information module that will hit the wire to the 86 box panel, so that the wall network cable outlet is installed.
Part5: the difference between the network cable and telephone line network cable and telephone line *** with 1 network cable and telephone line difference between the kitchen storage na kitchen storage a, the role of the different
1, the telephone line through the ADSL, will be the computer's digital signals modulated into an analog line number propagation through the telephone line to the other end of the telecommunication side of the analog signal demodulation into a digital signal later. Internet access is less modulation step.
2, bandwidth issues. Telephone line is affected by the physical bandwidth, the general bandwidth will not be too high (the maximum broadband value of 8M), the physical bandwidth of the network cable is relatively high (good cable can reach 1000M or even more)
Two, the interface is different
Why is it that the cat connected to the telephone interface, and the network interface connected to the top of the response is nothing, this is because of the signals from the phone line over the cat to be converted and processed in order to be forwarded to the network equipment. This is because the signal from the phone line has to be converted and processed by the cat before it can be forwarded to network devices, such as computers, routers, hubs and switches. If you connect it directly, then it is an analog signal that cannot be recognized, which is equivalent to no signal. In other words, the cat plays a role in the middle, is the conversion of the signal and simple processing, specifically the phone line over the analog signal into a digital signal to the network equipment, the network equipment to send digital signals converted to analog signals sent out through the phone line.
2 network cable and telephone line **** with good? Kitchen storage na kitchen storage options network cable and telephone line *** with a network cable method in small and medium-sized enterprises, especially small business network system is common. Some network managers for the enterprise to save money on integrated wiring considerations, in the telephone and network to do a neutralization, choose network cable and telephone line *** with a network cable method as a solution to the current situation. In order to avoid the later management as well as maintenance and troubleshooting considerations, it is not recommended that the telephone and network common a network cable.
Part6: Network common failure analysis and treatment 1 line failure Kitchen organizer Kitchen organizer line failure is the most common situation is that the line does not work, diagnose this failure can be used ping to check the line at the far end of the router port whether the line is still able to respond, or to detect whether the traffic on the line still exists. Once you find that the remote router port is not available, or there is no traffic on the line, the line may have failed. There are several ways to handle this. The first is to ping the router ports at both ends of the line to check if the ports at both ends are down. If one of the end ports is not responding then the router port may be down. If the near end port is down, check to see if the port plug is loose and the router port is down; if the far end port is down, notify the other side of the line to check. After this troubleshooting, the line is often clear. If the line is still not working, one possibility is the problem of the line itself, to see if the line is cut off in the middle; another possibility is the router configuration error, such as routing loop. That is, the far end of the port route and pointed to the near end of the line, so that the line is connected to the far end of the network users can not be, this kind of failure can be diagnosed using traceroute. The solution to the routing loop is to reconfigure the static or dynamic routing of the router ports.
2 Router Failures Kitchen Organizer Kitchen Organizer In fact, many of the cases of line failures involve routers, so it is also possible to attribute some line failures to router failures. However, the line involves routers at both ends of the line, so it is important to consider line faults that involve more than one router. Some router failures involve just the router itself; these failures are more typically high router CPU temperatures, high CPU utilization, and too little router memory headroom. The most dangerous of these is a high router CPU temperature, as this can cause the router to burn out. And both too high router CPU utilization and too small router memory margin will directly affect the quality of network services, for example, packet loss rate on the router will increase as the memory margin decreases. To detect this type of failure, you need to use a tool such as the MIB Variable Browser to read out the relevant data from the router's MIB variables. Usually, the network management system has a specialized management process that constantly detects the router's critical data and gives timely alarms. The only way to solve this kind of failure is to upgrade the router, expand the memory, etc., or re-plan the topology of the network. Another type of router failure is its own misconfiguration. For example, the configuration of the wrong type of protocol, the configuration of the wrong port and so on. This kind of failure is relatively rare, in the use of the early configuration of the router basically will not appear.
3 host failure kitchen organizer kitchen organizer host failure is a common phenomenon is the host of improper configuration. For example, the host configuration of the IP address conflicts with other hosts, or IP address is simply not in the subnet range, which will lead to the host can not connect. For example, the network segment range of the Taizhou Radio Management Bureau is 172.17.14.1-172.17.14.253, so the host address is only valid if it is set within this segment range. There are also some service setting failures. For example, improper E-Mail server settings result in not being able to send or receive E-Mail, or improper domain name server settings will result in not being able to resolve domain names. Another possibility for host failure is host security failure. For example, the host has no control over the redundant services such as finger, rpc, rlogin, etc. on it. Malicious attackers can attack the host through the normal services or bugs of these redundant processes, or even get the superuser privileges of the host.
4 Other failures of the host kitchen organizer kitchen organizer kitchen organizer such as improper **** enjoyment of the local hard disk, etc., will lead to malicious attackers to illegally use the resources of the host. Discovering host failures can be a difficult task, especially with malicious attacks by others. Possible vulnerabilities can usually be prevented by jian watching the host's traffic, or scanning the host's ports and services. When an attack on a host is detected, possible vulnerabilities should be analyzed and prevented immediately, and network administrators should be notified of the attack. Now, municipalities have installed firewalls, if the firewall address permissions are not set properly, it can also cause connection failures of the network, as long as attention is paid to the setup of the use of firewalls, such failures can be resolved.
