What is a Category 6 line and the difference between a Category 5 line and a Category 6 line

Category 6 lines. Yes, the transmission frequency of the cable is 1MHz 250MHz.

The transmission frequency of the Category 6 line is 1MHz 250MHz, and the Category 6 cabling system should have a large margin of comprehensive attenuation crosstalk ratio (PS-ACR) at 200MHz, which provides 2 times the bandwidth of the Category 5 line.

It is 100m, 155m for Category 5, and 200m for Category 6.

In short-distance transmission, Category 5, Category 5, and Category 6 can all reach 1Gbps, and the transmission performance of Category 6 cabling is higher than that of Category 5 and Category 5 standards, and it is most suitable for applications with transmission rates higher than 1Gbps.

Category 6 unshielded oxygen-free copper network cables.

The identification of the six types of unshielded network cables is: Cat 6, which is used for gigabit network, is now the hot new favorite of the weak current industry, and is composed of 4 pairs of twisted pair cables, 1 tensile rope, plastic sheath and cross. The colors of twisted pair are white-green, green, white-orange, orange, white-brown, brown, white-blue, and blue.

Compared with the super five network cables, the six types of unshielded network cables add an insulated cross, the cross with the length of the network cable changes and the rotation angle, the four pairs of twisted wires are placed in the cross plus four grooves, improve the balance characteristics of the cable and crosstalk attenuation, six types of unshielded network cable can generally reach about 10 years of life under normal use.

300 meters of network cable, the resistance of the six types of oxygen-free copper network cable is smaller than that of the super five categories, the super five categories are generally about 35 ohms, and the six types of network cables are only about 20 ohms, the performance is much higher than the super five types of network cables, <>

Six categories"It is mainly used for data transmission between switches, routers and computer jacks, and can also be used to transmit data such as medical CT scans and computer rooms, as well as other places that require massive data exchange and transmission.

Resources.

Category 6 line: used in communications, computers.

<>Category 5 network cable can undertake the transmission task of 100 Gigabit network speed, and Category 6 network cable can transmit Gigabit network speed in addition to 100 Gigabit network speed. When using Gigabit optical fiber, Category 5 network cable can only reach the transmission speed of 100 Gigabit network speed, and if Category 6 network cable only opens 100 Gigabit optical fiber, it can also produce the transmission effect of 100 Gigabit network speed. Category 6 cable performance in terms of crosstalk and return loss has been greatly improved, and the twisted pair has an additional insulated cross skeleton.

The logo of the Category 5 network cable on the outer skin is cat5, and the symbol of the Category 6 network cable is cat6.

The difference between Category 5 and Category 6 network cables:

1. The structure is different. There is an empty rack inside the 6th category, which can put 4 wires in the slot, which can play a fixed role, while the 5th category does not.

2. The wire core is different. The diameter of Class 6 is between millimeters, while the diameter of Class 5 is only millimeters at most, and it can be seen with the naked eye that the thickness of the two types of wires is different.

3. The logo is different. The outer packaging of Class 6 is written as cat6, and class 5 is written as cat5.

4. The performance is different. The former has a wide range of applications, and is not affected by shielding, and the transmission speed is very fast, and the performance far exceeds the latter.

Precautions for purchasing network cables.

Regardless of whether you purchase a Category 5 network cable or a Category 6 network cable, you need to pay attention to the following points when purchasing:

1. Before buying, you must remember to understand the quality of the thread, and you can use your hand to pull it to see if it will leave creases. If it can be quickly restored to its original state after wrenching, and there are no traces, it means that it is of good quality and can be purchased with confidence.

2. Be sure to remember to choose a reliable way to buy, you can go to your local store to buy, or you can buy it online. If you don't know about this aspect, then before buying, you can go to an experienced person to consult, listen to his opinion, you will definitely not go wrong, he asked to buy which model to buy.

The difference between Category 5 lines and Category 6 lines:

Category 5 network cable can undertake the transmission task of 100 Gigabit network speed, Category 6 network cable can transmit Gigabit network speed in addition to 100 Gigabit network speed, and Category 5 network cable can only reach the transmission speed of 100 Gigabit network speed when using gigabit optical fiber.

If the six types of network cable only open a hundred megabit of optical fiber, can also produce a hundred megabit network speed transmission effect, six types of network cable crosstalk and return loss performance has been greatly improved, twisted pair more than an insulated cross skeleton, there is a five types of network cable in the outer skin of the sign is cat5, six types of network cable sign is cat6.

First, the performance aspect.

The transmission performance of Category 6 network cable is higher than that of Category 5. The transmission bandwidth of the Category 5 network cable is 100MHz, while the Category 6 network cable can be used for 100MHz and can transmit gigabit network speeds. In addition, the transmission performance of the Category 6 cable is also more stable than that of the Category 5 cable, because the Category 6 cable is optimized in terms of cable crosstalk and echo loss.

2. Structure and shape.

Structurally speaking, the twisted pair in the 6 types of network cables has more cross skeletons, and the cable can be installed in the skeleton to play a good insulation effect. Secondly, the size of the copper core of the two is different, the copper core of Class 5 is below, and the copper core of Class 6 is in between: in terms of appearance, the outer diameter of the Category 5 network cable is thinner than that of the Category 6 network cable.

Three**. In terms of sales, because the Category 6 network cable has advantages over the Category 5 network cable in terms of material use and performance, it will be higher than the Category 5 network cable.

1. The internal structure of the six types of network cables and the five types of network cables is different: the internal structure of the six types of network cables has increased the 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 of the cable ** rotates with the change of length. Dou Xiang Sakura.

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 less than millimeter, the super 5th network cable is millimeter millimeter, and the standard of Category 6 network cable is millimeter millimeter.

3. Category 5 network cable: the outer skin monogram is marked with the word "cat5", the transmission bandwidth is 100MHz, which is used for voice transmission and data transmission with a maximum transmission rate of 100Mbps, mainly used for 100 megabit network and 10 trillion network, which has been replaced by super five category 5 cable.

2. Category 6 network cables: the outer skin is marked with the word "cat6", which generally refers to unshielded network cables, which are mainly used in gigabit networks, and are much higher than the super five network cable standards in terms of transmission performance.

Cat5e is a Cat5e line, and Cat6 is a Cat6 line.

The spacing of the pair of cat5e is relatively large, and the spacing of cat6 is relatively tight.

The transmission rate of CAT6 is much greater than that of CAT5E.

The cat6** is more expensive than the cat5e.

CAT5E is a general home network cable, and CAT6 is mainly used for data transmission between switches, routers and computer jacks.

The CAT6 has a thicker diameter than the CAT5E cable.

Compared with CAT5E, CAT6 adds an insulated cross-frame, and the four pairs of twisted pair wires are placed in the four grooves of the cross-frame.
