Are Category 55 cables the same as RJ45 cables?

Category 55 cable and RJ45 cable are not the same, Category 5e cable refers to the network cable. RJ45 cable refers to ** wire.

This category is different from the others, and they are all different ones as a whole, and not all of them are the same.

Of course, these two types of cables are different, and they are different in terms of cost performance.

Hello, these two are different cables. You can choose according to your actual needs.

RJ should still be the same for four or five days, and this computer should send things, and it is very difficult to choose what some philosophies think this is still a card.

Enhanced Category 5 unshielded twisted pair is a cable that has emerged after some of the performance of existing Category 5 shielded twisted pair has been improved.

Is the computer the same as that of the fifth-generation store? It's definitely not the same for me.

Copied the computer, the sound is relatively good, the day is serious, the computer should be the same effect, who would think that this weather is better taboo.

Don't be, this should be the specific cable those who borrowed the professional introduction to me to learn more about this aspect of the details.

Is it the same for the super 5 force cable R2 to the 45 super 5 cable? It's the same.

It must be different, because the model of this cable is different, so the function in it is also different.

CAT-5E is a CAT5e network cable, while HSYV-5E is a CAT5e twisted pair cable, the two have different names, but they are used on the network is the same, so the two are the same thing.

UTP stands for Unshielded Twisted Pair, which means unshielded twisted pair. 5E means CAT5e cable, and UTP 5E means CAT5e unshielded twisted pair cable.

The Category 5e unshielded network cable is composed of an unshielded twisted pair cable of a certain length and an RJ45 crystal head, and there are 8 network cables in the line, each two of which are entangled, so there are 4 network cables, and the reason for this is to reduce the impact of electromagnetic radiation and external electromagnetic interference as much as possible.

Main uses: Category 5A twisted pair cables are mainly used for communication companies or network companies to deploy outdoor short-distance links.

The maximum effective communication distance of ordinary Cat5 line is 100m, and the maximum communication distance of Cat5e can be 300m. And the service life of the outer protective layer is much longer than that of the ordinary Category 5 line.

Most of the wires connected to the router or switch from the cell gateway or the whole floor gateway are Category 5e cables.

The above content refers to Encyclopedia - Super Category 5 Line.

Category 5 or Category 5e is a standard to measure the speed of the transmission rate of twisted pair (network cable).

There is a difference: the higher the number before the 'class', the faster it transmits. At present, there are 3 categories commonly used, super 5 categories, 6 categories, and more high-end 7 categories (6a categories).

In the case of Category 5 twisted pairs, it has a standard transfer rate of 100Mbps. What is the concept? That is to say, '100 megabits can be transmitted in one second', usually 8 bits = 1 byte in storage, then 100mbps 8=, that is, megabytes can be transmitted per second.

However, the transfer of the past is not necessarily a valid encoding, according to the 80% encoding efficiency calculation, that is, a 100M file, can be transferred in 10 seconds.

In addition, the faster than Class 5 and Class 5 are Class 6 and Class 7 (Class 6a). The standard rate of Category 6 is 1000Mbps (commonly referred to as Gigabit), while the rate of Category 7 can reach 10000Mbps (commonly referred to as 10 Gigabit or 10Gbps). As for how fast the transfer speed is, you can calculate it according to the calculation above.

By the way, don't think that with a Category 6 network cable, you can reach gigabit speeds.

The deployment of 6 types of network cables only means that your cabling has the conditions to achieve gigabit speed, not that your network speed can reach gigabit, and the specific amount of bandwidth you apply for depends on how large the bandwidth you apply for at the operator.

The main differences are:

in the diameter of the conductor, that is, the size of the core. Class 5 is 26AWG (approximately equal to Class 5 is 24AWG (approximately equal to.

From the transmission, Category 5 is 100M+, and Category 5 is 10M+.

There are a variety of network cables on the market, in addition to international brands, I recommend the better ones in China: Ampsimon, Simon, Saimone. These brands have precision wiring technology.

Compared with imported brands, the quality is comparable. But be sure to look for the "Precision Series"!

"Super five categories"Refers to the Category 5 Unshielded Twisted Pair (UTP—Unshielded Twisted Pair) unshielded twisted pair cable is composed of multiple pairs of twisted pairs and a plastic sheath. Category 5 refers to the five different quality levels defined by the International Electrical Industry Association for twisted pair cables.

Category 5 network cable supports 100 megabits, which is suitable for bandwidth networks within 100 megabits.

Super 5 network cable supports Gigabit, suitable for bandwidth networks within 1000 megabits, because it can support higher bandwidth, so Super 5 network cable is better.

Category 5 wire: This type of cable increases the winding density, and is coated with a high-quality insulating material, with a transmission rate of 100MHz, which is used for voice transmission and data transmission with a maximum transmission rate of 10Mbps, mainly used for 100Base-T and 10Base-T networks. This is the most commonly used Ethernet cable.

Category 5e line: Category 5 has reduced attenuation, less crosstalk, and has a higher attenuation-to-crosstalk ratio (ACR) and signal-to-noise ratio (structural return loss), smaller time delay difference, and the performance is greatly improved. Category 5 cables are mainly used for Gigabit Ethernet (1000Mbps).

Everyone should not know what Category 5 network cable and Category 5 network cable are, whenever it is mentioned Category 5 network cable and Category 55 network cable, it is confusing. Aren't all network cables the same? Why are there so many differences, so today I will tell everyone what the super five network cable means!

1. The division of five types of network cables is determined according to the electrical properties of twisted pair cables, each of which will represent a different quality level. These types of network cables have become our first choice because of the advantages of being cheap and cheap, and they contain four pairs of copper unshielded twisted pair cables equipped with RJ-45 connectors.

2. Category 5e network cable, that is, Category 5e twisted pair, there are two classifications, namely Category 5 unshielded twisted pair and Category 5 shielded twisted pair. Category 5e optimizes some of the performance on the basis of the existing Category 5 shielded twisted pair cables.

The above is what the super five network cable I brought to you means, I believe you will be clear after reading this article.

The UTPs used today can be divided into four types: Category 3, Category 4, Category 5, and Category 5. Among them: Category 3 UTP adapts to the requirements of Ethernet (10Mbps) for transmission medium, and is an important transmission medium in early networks; Class 4 UTP is generally less used and basically eliminated because the standard was launched later than Class 3, and the transmission performance is not much improved compared with Class 3 UTP!

Category 5 UTP has become the preferred medium for Fast Ethernet (100Mbps) due to its low price and high quality; Where Category 5e UTP comes into play is Gigabit Ethernet (1000Mbps).

The twisted pair in the computer LAN can be divided into two categories: unshielded twisted pair (UTP) and shielded twisted pair (STP): the STP is wrapped by a layer of metal material to reduce radiation and prevent information from being eavesdropped, and at the same time has a high data transmission rate, but it is higher and the installation is more complicated; UTP is no metal shielding material, only a layer of insulating rubber wrapping, relatively cheap, flexible networking. Except for some special occasions (such as serious electromagnetic radiation, high requirements for transmission quality, etc.) STP is used in wiring, UTP is generally used

CAT5e network cable model.

It is recommended to go to the specialty store to see, because there are brands.

It's not the same thing to say here.

There are generally many kinds of network cables, such as: Category 5 network cables, Category 5 network cables, Category 6 network cables, Category 6 network cables, etc., but many people are not very clear about the difference between these network cables, so what is the difference between Category 5 and Category 5 network cables? Let's take a look with the small scattered Qing clan.

1. The skin logo is different.

The words "cat5e" are generally marked on the outer skin of the network cable of the super five network cables, and the words "cat5e" are generally marked on the outer skin of the network cable of the five network cables.

2. The scope of use is different.

The bandwidth of the Category 5e network cable is generally 155M, which can be used to support the network of 100 megabits and above, and can also be used in the local area network, so it is a more popular network cable product on the market. The bandwidth of the five types of network cables is generally 100M, which can only be used to support networks below 100 megabits.

3. The rate of transmission signal is different.

The rate of signal transmitted by the Category 5 network cable can generally be as high as 100MHz, and the rate of the signal transmitted by the Category 5 network cable is generally below 100MHz, so the performance of the Category 5 network cable is generally better than that of the Category 5 network cable.

4. The size of the outer diameter is different.

The outer diameter of a CAT5e cable is generally thicker than that of a CAT5e cable.

5. The internal configuration is different.

A tenacle cable is generally added to the internal structure of the Category 5 network cable, while a tensile cable is generally not added to the internal structure of the Category 5 network cable.

6. The transmission distance is different.

CAT5e cables can generally transmit effective distances of up to 300 meters, so they are often used by communication network companies to deploy connections between outdoor short distances. The effective transmission distance of the five types of network cables generally does not exceed 100 meters, so it can only be used for short-distance communication applications.

7. The number of internal copper core wires is different.

When transmitting data, Category 5 network cables generally use 4 pairs of copper core cables for transmission, so they can generally support duplex applications, while Category 5 network cables generally use 2 pairs of copper core cables for transmission when transmitting data, so they can generally only support half-duplex.

The above is a detailed introduction to what is the difference between Category 5 and Category 5 network cables, I hope it can help you distinguish between Category 5 and Category 5 network cables. When you choose a network cable, you must choose according to the actual situation and your own needs, so as to avoid problems.

The difference between Category 5 and Category 5 network cables: 1. The wire skin identification is different: Category 5 network cable is cat5, and Category 5 network cable is the highest speed is different

The maximum signal rate transmitted by the five types of network cables is 10MHz; The highest rate of signal transmitted by the CAT5e cable is 100MHz, and its performance is better than that of the CAT5 cable, and some indicators have also been improved. 3. Different network cables: Category 5 network cables use two pairs of copper core cables to transmit data, supporting half-duplex; The Category 5e cable uses four pairs of copper core cables to transmit data and can support duplex applications.

4. The effective transmission distance of the ridge is different: the effective transmission distance of the five types of network cables does not exceed 100m, which is more suitable for short-distance communication applications; The communication distance of the Category 5e network cable can reach up to 300m, which is mainly used for communication network companies to deploy outdoor short-distance branches. At present, most of the network cables used to connect routers and cell gateways are Category 5e network cables.

5. The protective layer outside the Category 5 network cable is better than the protective layer of the Category 5 network cable, and the service life is much longer than that of the Category 5 network jumper. 6. Category 5 network cable is the basis of Category 5 unshielded twisted pair cable, and the performance of end crosstalk, attenuation crosstalk ratio, return loss and other performance of Category 5 unshielded twisted pair cable has been greatly improved, but its transmission bandwidth is still 100MHz.

7. The CAT5e network cable has reduced attenuation, less crosstalk, and has a higher attenuation to crosstalk ratio (ACR) and a lower time delay difference, and the performance has been greatly improved.
