What is the difference between 5A5E and what does Class 5E mean?

1. The internal structure is different. The internal structure of the six types of network cables 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 of the cable ** rotates with the change of length. There is no cross skeleton inside the Category 5 network cable.

2. The size of the copper core is different. The copper core of the five types of network cables is below, and the standard of the six types of network cables is different for the external labeling. The outer skin of the five types of network cables will be marked with the word "cat5"; The outer skin of the six types of network cables will be marked with the word "cat6".

4. The scope of application is different. Category 5 network cables are mainly used for 100 Gigabit networks and 10 Gigabit networks, and have been replaced by Super Category 5 cables. Category 6 network cables are mainly used in gigabit networks, and their transmission performance is much higher than that of Category 5e network cable standards.

The Category 5e network cable is the Category 5e cable.

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 for voice transmission and data transmission with a maximum transmission rate of 100Mbps, 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.

structuralreturn loss), smaller time delay difference, and greatly improved performance. CAT5 line.

Mainly used for Gigabit Ethernet (1000Mbps).

The 5E network cable is an AMP network cable, and the cat5e logo indicates that the network cable is a Category 5 cable.

With the development of network technology, the physical layer transmission protocol 1000BASE-T based on Category 5 also has the transmission capacity of Gigabit Ethernet (1,000,000,000 bit s), which realizes a smooth transition from 100 Gigabit to Gigabit while retaining the original cable.

Therefore, after automatic negotiation between the devices at both ends, the Cat5 cable can work at 100MHz at 10BASE-T, 100BASE-TX (Fast Ethernet), and 1000BASE-T (Gigabit Ethernet) and other technologies to undertake different rates of Ethernet transmission media. In order to ensure the transmission quality, the transmission distance of the five types of lines is generally within 100 meters.

The 5E network cable is the super Cat5e network cable.

Super Category 5"It refers to the Category 5e unshielded twisted pair (UTP) and the Category 5e shielded twisted pair. An unshielded twisted pair cable consists 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.

Twisted pair cables in computer LANs 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. At the same time, it 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.

Network cables are divided into five types of lines, super five types of cables, and so on. Then, there are shielded Cat5e wires and there are unshielded Cat5e wires. There is a shielded anti-interference, but because there is a shielding layer inside, the cost is also higher, so it is more expensive.

The common twisted pair cables are Category 3 cables, Category 5 cables, super Category 5 cables, Category 6 cables, and the latest Category 7 cables.

The former has a thin wire diameter and the latter has a thick wire diameter, and the models are as follows:

Class 1 cable: mainly used to transmit voice (a class of standards is mainly used for ** cables before the early eighties), different from data transmission.

Category 2 line: The transmission frequency is 1MHz, which is used for voice transmission and data transmission with a maximum transmission rate of 4Mbps, which is commonly found in the old back-to-back token network that uses the 4Mbps specification token passing protocol.

Category 3 cable: The cable specified in the ANSI and EIA TIA568 standards, the cable has a transmission frequency of 16MHz for voice transmission and data transmission with a maximum transmission rate of 10Mbps is mainly used for 10BASE--T.

Category 4 cable: This type of cable has a transmission frequency of 20MHz and is used for voice transmission and data transmission with a maximum transmission rate of 16Mbps, mainly with a leakage cover for token-based LAN and 10BASE-T

Category 5 wire: This type of cable has a winding density added to the key source, and is coated with a high-quality insulating material with a transmission rate of 100MHz for voice transmission and data transmission with a maximum transmission rate of 100Mbps

Class E network cable is a super Category 5e cable. 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 100Mbps, mainly used for 100BASE-T and Latong 10BASE-T networks.

This is the most commonly used Ethernet cable.

The words "cat5e" are generally marked on the skin of the super five network cables, and the words "cat5e" are generally marked on the skin of the five network cables. The outer diameter of the CAT5e cable is generally thicker than that of the CAT5 cable.

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).

Indication is different: Category 5 network cable is often marked with "cat5", which is suitable for broadband below 100 meters. The Super Five has "cat5e", which is mainly used in gigabit networks, and is also widely used in the setting of local area networks, which belongs to the current mainstream network cables.

Category 5 line, the abbreviation of the English brother is: catIt is a communication cable commonly used for voice transmission, that is, the ** line. The common ** line is much thinner than the network cable, but the network cable can be used as a ** line.

The first issue of network cable cognition, serious science series, teaches you how to recognize the difference between six types of network cables and five types of network cables, which is very easy to understand.
