How to distinguish and use Gigabit Ethernet cable and 100M Ethernet cable in weak current engineering?

The choice of network cable in the integrated wiring system is very important. Is the network cable selection the same in computer networks and video surveillance systems? When do you use Gigabit Ethernet cable and when do you want a 100M network cable?

In the era of Internet information communication, people's dependence on the network is becoming more and more serious. The speed of the network directly affects our daily life. Do you know that the network cable is also divided into different rates? For example, 100M network cable, Gigabit network cable. Then, in what kind of scenario, the 100 Mbps network cable is used, and in what kind of scenario, the Gigabit network cable is used. This article will explain in detail.

How to distinguish between Gigabit network cable and 100M network cable

Gigabit network cables and 100 megabit network cables are generally distinguished by the specification or parameters of the network cable.

(1) Gigabit network cable

In general, the transmission rate of Cat6 Category 6 cable is 1000 Mbps, while the transmission rate of Cat6a Category 6 and above is more than 10 Gbps. Therefore, the Cat6 Category 6 cable is called Gigabit cable.

(2) 100M network cable

Usually, the main transmission rate of Cat5e Super Category 5 cable is between 100 Mbps and 1000 Mbps. It can also be used for Gigabit transmission under certain conditions, but the effect is not good. The main transmission rate of Cat5 Category 5 cable is 100 Mbps, so Cat5e will be used. The Super Category 5 network cable and the Cat5 Category 5 network cable are called 100M network cables.

But in fact, we need to know that the cable specification guarantees the electrical transmission performance, not the network speed. The actual network speed is not only related to the network cable, but also has a great relationship with the terminal equipment.

How to choose Gigabit network cable and 100M network cable

Faced with different network transmission requirements, Gigabit Ethernet and 100M Ethernet cables can play different roles. When the required transmission rate is mainly 1000 Mbps, the Gigabit network cable is used; when the required maximum transmission rate does not exceed 1000 Mbps, the 100M network cable can be used. The following shows the related cases of Gigabit Ethernet and 100M Ethernet:

(1) Cat6 Category 6 Gigabit Cable – Horizontal Cabling Solution

When you need to carry out horizontal cabling of Gigabit networks, you can choose Cat6 Category 6 unshielded (UTP) Ethernet Gigabit Ethernet cable with card slot protection design and RJ45 connector for stable transmission of Gigabit network. As shown below:

(2) Cat5e super five types of 100M network cable – Ethernet fiber optic transceiver wiring scheme

The Cat5e Super Category 5 unshielded (UTP) card slot 100 Mbps cable is designed for connection to Ethernet media transceivers and Ethernet switches. As shown below:

Can Gigabit and Baiwei cable be universal?

In the 100M network, the Cat5 Category 5 100M network cable uses only 4 cores in the process of transmitting network signals. In the Gigabit network, the Cat6 Category 6 network cable uses 8 cores in the transmission network signal. The four cores of the Cat5 Category 5 network cable can not transmit and receive at the same time as the Gigabit network transmission, that is, the four cores can only realize the Gigabit network to receive data or send data. The two cannot be simultaneously performed, but the specifications of the network port are the same. Therefore, the Cat5 Category 5 100M cable and the Cat6 Category 6 Gigabit cable cannot be fully versatile.

The Cat5 Category 5 network cable has not been adopted any more. Today, the 100M network cable mainly refers to the Cat5e Super Category 5 network cable. The Cat5e Super Category 5 network cable is the same as the Cat6 Category 6 network cable. It is an 8-core twisted pair cable. Therefore, Cat6 Category 6 can be used. The network cable can be used for 100-megabit transmission. It can also be used for Gigabit transmission under certain conditions by Cat5e super five network cable. It can be used universally.

However, it is worth noting that the Gigabit cable crystal head and the 100M cable crystal head are not universal. Their copper cores are different in size, so the size of the internal holes is also different.

to sum up

In fact, we can see from the above that the Gigabit Ethernet cable and the 100M Ethernet cable are a relatively rough division. If you really want to subdivide, you need to divide it with Cat5, Cat5e, Cat6, Cat6a, etc., and then according to the parameters. Analysis and purchase.
