Could the CAT5e network cable be used in a gigabit network?

April 26, 2021

Recently, a customer consulted in the background that the home is being renovated, and the Category 5 Network Cable has been laid, and now he wants to implement a gigabit network. So can the super five network cable reach the speed of gigabit? Let’s let the editor of Kaiweier answer it for you now


The CAT5e network cable has the CAT5 unshielded network cable and the CAT5 shielded network cable. The shielded cable is mainly made of better wires and an extra layer of shielding. In the decoration, it is inevitable that it will be pulled together with the power cord in many cases.
At this time, the shielding layer can well shield the electromagnetism generated by the power cord, which greatly reduces the interference to the transmission signal of the network cable in the shielding layer. Make the signal transmitted in the network cable more stable and reduce the occurrence of data packet loss.
Theoretically, Category 5e network cable can be used for Gigabit Ethernet.

Cat5e network cable, the outer skin is marked with "CAT5e", the transmission bandwidth can be as high as 1000Mb/s, but it is generally only used in a 100Mb/s network, and only connects the desktop switch to the computer.
Because the Super Category 5 unshielded network cable needs the support of expensive special equipment.

Extended information:

The advantages of the super five network cable:

Because users' wireless routers, NAS, desktops and other devices require wired connections, the 100M transmission provided by Category 5 cables cannot be supported. It is recommended that users change to at least Category 5 cables.
When decorating, try to lay the network cables in Category 6 or Super Category 6 and above to avoid the situation that later cables cannot be upgraded in the wall.

The UTP currently in use can be divided into three types, four types, five types, super five types, six types, and super six types.
Among them: Type 3 UTP meets the requirements of Ethernet (10Mbps) for transmission media and is an important transmission medium in early networks; Type 4 UTP is later than Type 3 due to the introduction of the standard, and the transmission performance is not compared with Type 3 UTP. How much to improve,
So generally used less;

Category 5 UTP has become the preferred medium for fast Ethernet (100Mbps) because of its low price and high quality; the application of Category 5 UTP is gigabit Ethernet (1000Mbps). To achieve gigabit speed,
In addition to using a good network cable, you also need to support the equipment at both ends of the network cable.
