What is the difference between Category 5 and Category 6 network cables?

1. The super five types of unshielded twisted pair is a cable that appears after the improvement of part of the performance of the existing five types of shielded twisted pairs, many performance parameters, such as near-end crosstalk, attenuation crosstalk ratio, return loss, etc., have been improved, but its transmission bandwidth is still super five types of unshielded twisted pair can also provide up to 1000mb s of transmission bandwidth, but often need to rely on the support of high special equipment. As a result, Tongdu is often only used for 100MB S Fast Ethernet to enable desktop switchback to computer connections. 3. The parameters of the six types of unshielded twisted pair cables have been greatly improved, and the bandwidth has also been extended to 250MHz or higher.

A4. Category 6 unshielded twisted pair cable can support Gigabit Ethernet very well and achieve a transmission distance of 100m. 5. As a long-term basic investment, the integrated wiring should fully consider the potential needs of the network and the development of the wiring system, therefore, under the condition that the funds allow, it is recommended to choose six types of products to build the wiring system.

The difference between Category 5 and Category 6.

Category 5 network cable is a transmission bandwidth of 100MbpsThe outer skin of the network cable is marked with the "cat5" logo. Category 6 network cable is a transmission bandwidth of 1000MbpsThe "cat6" is used in gigabit networks, and its performance is much higher than that of Category 55 twisted pairs.

The following details the differences between Category 5 network cables and Category 6:

First, the appearance of the structure is different

The identification of the Cat5 line is CAT5, and the logo of the CAT5E line is CAT5E, which is the current mainstream product; The identification of the Category 6 line is cat6.

There is no isolation belt in Category 5 and Category 5 cables, and there is an insulated cross isolation belt in Category 6 network cables. The thickness of the wire diameter, if you compare, you will find that the line diameter of the sixth class line is thicker than the line diameter of the fifth class line, of course, it is also more expensive.

Second, the transmission rate is different

The maximum transmission rate of Category 5 is 100m, while the maximum transmission rate of Category 5 and Category 6 is 1000m. However, the transmission performance of Category 6 lines is higher than that of Category 5e cables, and an important difference between Category 6 lines and Category 5e cables is the improved performance in terms of crosstalk and return loss. Owners who are not familiar with this only need to check the internal structure and appearance of the network cable, in the home network decoration.

If the economy allows, it is recommended to choose six types of lines, with stronger anti-interference ability, after all, now the technology is becoming more and more developed, and smart home will become the mainstream. However, it is not recommended to buy network cables on the network Category 5 cable: Category 5 cable has been eliminated, the maximum transmission rate of the network is 100mbps, and there may be Category 5 lines on the market pretending to be more than Category 5 cables.

3. Appearance identification

The five types of lines have a thinner diameter and a "logo" on the skin, which has now been eliminated. For more than Category 5 wires, the network cable table has the logo of ", and the wire core is much thicker than that of Category 5 wires. Category 6 wires, there is a "cross skeleton" in the middle of the network cable to separate the pairs, reducing crosstalk, and the skin of the network cable has a "logo".

Fourth, the core specifications are different

The diameter of the core of the Category 5 wire is basically disappeared from the market and replaced by the Category 5 wire. The standard of Cat5e wire is 24AWG, that is, the core diameter is. The standard for Class 6 wire is 23AWG, that is, the core diameter is.

1. The difference between appearance labeling:

On the insulating skin of the network cable, there will be a string of black English, and the super five network cable will have the words cat5e; The CAT6e cable says cat6e.

Category 5 cable is CAT5, Category 6 cable is CAT6, and there is also CAT3 (Category 3 network cable) circulating in the market.

2. Differences in structure:

Peel off the insulating skin of the network cable, you can see that there are 8 small wires in the network cable, each 2 are wound together to form a pair, a total of 4 pairs - this is the origin of the name "twisted pair".

4 pairs of twisted pair cables of CAT5e network cables, directly wrapped in insulating skin; In the Cat6e network cable, a cross skeleton is added in the middle of the insulating holster, and each pair of twisted pair cables is fixed in the groove of the cross skeleton.

3. Performance differences:

The transmission speed of the CAT5e network cable can reach up to gigabit (1000mbps);

The transmission speed of CAT6e network cable can reach up to 10,000 Mbps (10,000 mbps).

Answer: 1. The identification of different categories of super five is cat5e, and the identification of category six is different transmission speeds, and the six types of network cables are mainly used in gigabit networks, and the maximum transmission speed can be up to 10,000mbps. The performance is much better than that of the Category 5e network cable. The Category 5e cable can transmit up to 1000MB s, but it is usually used in a 100MB s network.

1. Different classifications: CAT5E and CAT6 are two different types of network cables, CAT5E belongs to the super five types of network cables, and CAT6 belongs to the six types of network cables. Although the classification is different, both work on the same principle, both have the same type of RJ-45 plug, and are able to plug into any Ethernet jack on a computer, router, or other similar device.

2. Different transmission bandwidth: the transmission frequency bandwidth of CAT5E is 100MHz, while the transmission frequency bandwidth of CAT6 is 250MHz, and there is an obvious gap between the two.

3. The difference in maximum transmission speed and distance: Cat5E network cable is used in Gigabit Ethernet, with a transmission distance of up to 100m and a transmission speed of 1000Mbps. The CAT6 cable can provide up to 10Gbps transmission speed in 250MHz bandwidth.

CAT6 is best suited for applications with transfer rates of 1Gbps.

4. Different applications using 10GBASE-T: The transmission distance of CAT5E network cable and CAT6 network cable is 100M, but when using 10GBASE-T applications, the transmission distance of CAT6 network cable can reach up to 55m.

Fifth, the difference in transmission performance: the CAT6 network cable has an internal splitter, which can reduce interference or near-end crosstalk (NEXT), compared with the CAT5E network cable, it also improves the far-end crosstalk (ELFEXT), and the return loss and insertion loss are lower, therefore, the performance of the CAT6 network cable is better.

When using computers and wires, people often ignore the choice of network cables. If the network cable is not selected properly, it will affect the transmission of signals, affect the network speed, and affect the good use of the computer. There are many types of network cables, so what is the difference between Category 6 and Category 5 network cables?

From the point of view of identification, the identification of the fifth class is cat5, and the identification of the sixth class is cat6; From the perspective of transmission speed, Category 5 is mainly used for 100 Gigabit networks, while Category 6 is mainly used for Gigabit networks, and Category 6 has faster transmission speeds; From the perspective of internal structure, the interior of Category 5 is generally four pairs of lines, while the interior of Category 6 will be set up with a skeleton to reduce crosstalk between signals.

What are the ways to purchase network cables?

1. Look at the network cable identification.

On the outer skin of the network cable, there is a letter identification of the network cable, and we can judge its type by the letter identification. Generally speaking, cat5 refers to Category 5 network cable, which can be used for networks below 100 megabits, while the letter cat6 refers to Category 6 network cables, which can be used for gigabit networks. And the high-quality network cable, the letters on the outer skin are clearly visible, while the font of the inferior network cable is not very clear.

2. Look at flexibility.

In order to meet the needs of different network uses, generally speaking, Category 5 and 6 network cables mostly use copper wires as conductors, which are soft, flexible and not easy to break. When we buy, we can feel its feel, if the feel is soft, good bendability, it means that the quality is better, if it feels hard, difficult to bend, it means that the quality is poor.

3. Burn with fire.

When purchasing, we can put the network cable under the fire to burn for a while, to observe whether its skin will become soft, if the skin is not soft, there is a certain burning phenomenon, it means that the quality is not up to standard, if the skin is soft, not burning, it means that the quality is good.
