The difference between network cable category 5 and category 6
The difference between Category 5 and Category 6 of network cables is as follows:
1. Internal structure: the internal structure of the 6 network cable is added to the cross skeleton, and the 4 pairs of cables of the twisted pair are placed in the 4 grooves of the skeleton, and the cross skeleton in the cable rotates the angle due to the change of length. However, Category 5 lines do not have this construction. 2. Copper core size: The copper core of Category 5 network cable is less than 0.45 mm, while the specification of Category 6 network cable is between 0.56 and 0.58 mm.
3. Transmission bandwidth: Category 5 network cables allow 100Mbps transmission, suitable for 100 megabit and 10 megabit networks. Category 6 network cable exceeds 1,000Mbps, mainly suitable for gigabit data transmission, so from the perspective of transmission performance, Category 6 network cable far exceeds the Category 5 network cable standard.
Category 7 network cable
The latest twisted pair in ISO/IEC 118017/F standards, which is mainly to adapt to the application and development of 10 Gigabit Ethernet technology. BUT IT IS NO LONGER AN UNSHIELDED TWISTED PAIR, BUT A SHIELDED TWISTED PAIR, SO IT CAN PROVIDE A COMPREHENSIVE ATTENUATION-TO-CROSSTALK RATIO OF AT LEAST 500MHZ AND AN OVERALL BANDWIDTH OF 600MHZ, MORE THAN TWICE THAT OF CAT SIX AND SUPER SIX CABLES, AND A TRANSMISSION RATE OF UP TO 10Gbps. In the seven types of cables, each pair of wires has a shield, and together the four pairs have a common large shield.
From a physical point of view, the additional shielding layer allows the CAT 7 wire to have a larger wire diameter. ANOTHER IMPORTANT DIFFERENCE IS ITS ABILITY TO CONNECT HARDWARE, AND THE PARAMETERS OF THE SEVEN TYPES OF SYSTEMS REQUIRE THAT ALL PAIRS OF WIRES AT 600MHZ PROVIDE AT LEAST 60DB OF INTEGRATED PROXIMAL STRING. THE SUPER FIVE SYSTEM ONLY REQUIRES 43DB AT 100MHZ, AND THE VALUE OF CLASS SIX AT 250MHZ IS 46DB.
What is the difference between CAT 6 and CAT 5?
First, the subject is different
1. Category 6 network cable: It is a cable that meets the CAT-6 standard.
2. Super Category 5 network cable: It is Super Category 5 unshielded twisted pair and Super Category 5 shielded twisted pair.
Second, the specifications are different
1. Category 6 network cable: using single-core bare copper with specification 23AWG as conductor, polyethylene polymer material as insulator, and flame-retardant polymer material with gray color for outer skin material.
2. Super Category 5 network cable: the outside is wrapped by a layer of metal material to reduce radiation and prevent information from being eavesdropped. At the same time, it has a high data transmission rate, but the price is higher and the installation is more complicated.
Third, the characteristics are different
1. Category 6 network cable: cable center cross isolation ensures NEXT performance and reasonable construction bending radius. It can be used for voice, integrated service data network (ISDN), ATM 155Mbps and 622Mbps, 100Mbps TPDDI.
2. Super Category 5 network cable: The word CAT5 should be printed on the outer breadcrust of the twisted pair cable, indicating that the twisted pair is a CAT 5 twisted pair of AMP (the most reputable twisted pair brand).

The difference between a CAT 6 network cable and a CAT 5 network cable
First, the transmission frequency is different
1. Category 6 network cable: the transmission frequency is 250MHz.
2. Category 5 network cable: the transmission frequency is 100MHz.
Second, the use is different
1. Category 6 network cable: most suitable for applications with transmission rates higher than 1Gbps, mainly used for Gigabit Ethernet (1000Mbps).
2. Category 5 network cable: used for voice transmission and data transmission with a maximum transmission rate of 100Mbps, mainly used for 100BASE-T and 10BASE-T networks.
Third, the characteristics are different
1. Category 6 network cable: There are certain differences from Category 5 or super 5 twisted pair in appearance and structure, not only increasing the insulated cross skeleton, but also placing the four pairs of wires of the twisted pair in the four grooves of the cross skeleton, and the diameter of the cable is thicker.
2, five types of network cable: is the most commonly used Ethernet cable, this type of cable increases the winding density, jacket a high-quality insulation material.

Category 5, super Category 5, Category 6 cable, network cable, how to distinguish
The distinction is as follows:
1. The internal structure of the six-category network cable and the five-category network cable is different, the internal structure of the six-category network cable adds a cross skeleton, and the four pairs of cables of the twisted pair are placed in the four grooves of the cross skeleton, and the cross skeleton in the center of the cable rotates the angle with the change of length;
2. The copper core size of Category 6 network cable and Category 5 network cable is different, the copper core of Category 5 network cable is 0.45mm or less, the super Category 5 network cable is 0.45mm-0.51mm, and the standard of Category VI network cable is 0.56mm-0.58mm.
3. Category 5 network cable: the outer skin will be marked with the word “CAT5″, the transmission bandwidth is 100MHz, used for voice transmission and data transmission with a maximum transmission rate of 100Mbps, mainly used for 100 Gigabit networks and 10 Gigabit networks, which have been replaced by super five Category 5 lines.
4. Super five network cable: the outer skin is marked with the word “CAT5e”, the transmission bandwidth can be as high as 1000Mb/s, but it is generally only used in the 100Mb/s network, only to realize the connection of the desktop switch to the computer, because the super five unshielded network cable should be supported by expensive special equipment.
5. Category 6 network cable: The outer skin is marked with the word “CAT6″, which generally refers to unshielded network cable, which is mainly used in gigabit networks, and its transmission performance is much higher than that of super five network cable standards.
Extended Information:
The type of network cable
Twisted pair can be divided into unshielded twisted pair (UTP) and shielded twisted pair (STP).
The outer layer of shielded twisted pair cable is wrapped by aluminum platinum to reduce radiation, but it can not completely eliminate radiation, shielded twisted pair is relatively expensive, and it is more difficult to install than unshielded twisted pair cable.
Unshielded twisted pair cable has the following advantages: unshielded jacket, small diameter, saving the space occupied; Light weight, easy to bend, easy to install; Minimize or eliminate near-end crosstalk; It is flame retardant; Independence and flexibility for structured cabling.
Common models of twisted pair are as follows:
Class I cable (CAT1): mainly used to transmit voice (a class of standards was mainly used for telephone cables before the early eighties), different from data transmission.
CAT2: TRANSMISSION FREQUENCY 1MHZ FOR VOICE TRANSMISSION AND DATA TRANSMISSION WITH A MAXIMUM TRANSMISSION RATE OF 4MBS, COMMONLY FOUND IN OLDER TOKEN NETWORKS USING THE 4MBPS SPECIFICATION TOKEN DELIVERY PROTOCOL.
Category 3 (CAT3): transmission frequency 16MHz, used for voice transmission and data transmission with a maximum transmission rate of 10Mbps is mainly used for cables specified in the ANSI and EIA/TIA568 standards.
CAT 4 (CAT4): The transmission frequency is 20MHz, for voice transmission and the transmission rate up to 16Mbps is mainly used for token-based LANs and 10BASE-T/100BASE-T.
CAT 5 (CAT5): The transmission frequency is 100MHz, used for voice transmission and the highest transmission rate of 100Mbps data transmission, mainly used for 100BASE-T and 10BASE-T networks, which are the most commonly used Ethernet cables, this type of cable increases the winding density, jacketed with a high-quality insulation material.
CAT 5e (CAT5e): The transmission frequency is 100MHz, mainly used for Gigabit Ethernet (1000Mbps).
With small attenuation, less crosstalk, and higher attenuation-to-crosstalk ratio (ACR) and signal-to-noise ratio (StructuralReturn Loss), smaller time delay difference, the performance is greatly improved.
CAT 6 (CAT6): The transmission frequency is 250MHz, which is best used for applications with transmission rates higher than 1Gbps, mainly for Gigabit Ethernet (1000Mbps).
Category VI twisted pair has certain differences from Category V or Super Category V twisted pair in appearance and structure, not only increasing the insulated cross skeleton, placing the four pairs of twisted pair wires in the four grooves of the cross skeleton, but also the diameter of the cable is thicker.
Super Class 6 or 6A (CAT6A): The transmission frequency is 200~250 MHz, and the maximum transmission speed can also reach 1000 Mbps, which is mainly used in gigabit networks.
The Super Category 6 cable is an improved version of the Category 6 line, which is also an unshielded twisted pair cable specified in the ANSI/EIA/TIA-568B.2 and ISO Class 6/E standards, which has greatly improved crosstalk, attenuation and signal-to-noise ratio.
CAT 7 (CAT7): The transmission frequency can reach at least 500 MHz and the transmission rate can reach 10 Gbps, which is mainly to adapt to the application and development of 10 Gigabit Ethernet technology. This wire is the latest shielded twisted pair in the ISO Class 7/F standard.
