What is the difference between Ca5e, Cat6, and Cat7?

Category Five (CAT5): The transmission frequency is 100MHz, used for voice transmission and data transmission with a maximum transmission rate of 100Mbps, mainly used in 100BASE-T and 10BASE-T networks. This is the most commonly used Ethernet cable. This type of cable increases the winding density and coats a high-quality insulating material. Now the Category 5 cable is basically not used much.

Category 5e (CAT5e): The transmission frequency is 100MHz, mainly used for Gigabit Ethernet (1000Mbps). It has small attenuation, less crosstalk, higher attenuation and crosstalk ratio (ACR) and signal-to-noise ratio (Structural Return Loss), and smaller delay error, and the performance is greatly improved. In actual projects, although Category 5 cables can also transmit gigabit, it is only recommended for short-distance gigabit transmission. Long-distance gigabit transmission may be unstable. This is also a common fault in the project, and it is easy to ignore. The problem.

Category Six (CAT6): The transmission frequency is 250MHz, which is most suitable for applications with transmission rates higher than 1Gbps, mainly for Gigabit Ethernet (1000Mbps). Category 6 twisted pair is different from Category 5 or Category 5 super twisted pair in appearance and structure, not only an insulating cross frame is added, but the four pairs of twisted pair are placed on the four sides of the cross frame respectively. inside a groove, and the diameter of the cable is also thicker.

Super six or 6A (CAT6A): the transmission frequency is 200 ~ 250 MHz, the maximum transmission speed can also reach 1000 Mbps, mainly used in gigabit networks. Category 6e cable is an improved version of Category 6 cable. It is also an unshielded twisted pair cable specified in ANSI/EIA/TIA-568B.2 and ISO Category 6/Class E standards. Compared with other aspects, there is a big improvement.

Category Seven (CAT7): The transmission frequency can reach at least 500 MHz and the transmission rate can reach 10 Gbps. It is mainly to adapt to the application and development of 10 Gigabit Ethernet technology. This line is the latest shielded twisted pair in the ISO Category 7.

The main difference between various types of wire

Difference 1: The difference in loss, an important difference between Category 6 cable and Category 5e network cable is the improved performance in terms of crosstalk and return loss. It is recommended to use Category 6 network cables directly for home decoration.

Difference 2. The thickness of the wire core is different. The wire core of the super five type network cable is between 0.45mm and 0.51mm, and the wire core of the six type network cable is between 0.56mm and 0.58mm. The network cable is much thicker;

Difference 3: The cable structure is different. The outer surface of the super five-type network cable has the “CAT.5e” logo, and the six-type network cable has the most obvious “cross frame”, and the skin has the “CAT.6″ logo.
