Does network affect speed?

I believe that many of my friends have had such questions. They have upgraded the broadband at home and replaced the optical modem and router, but the network speed has not changed? You may have overlooked the optimization of the network cable. The network cable is directly related to network speed as the transmission medium of network data. What effect does the network cable have on the network speed? Let’s take a look together~

Type of network cable

The standard network cables on the market include Cat5e network cable, Cat6 network cable, Cat6e network cable, Cat7 network cable, and Cat8 network cable. The transmission rate and frequency bandwidth of each network cable is different.

1) Cat5e network cable The network cable generally has the logo of Cat.5E, the frequency bandwidth is 100MHZ, and the transmission rate is 100Mbps. Category 5 super network cable is an upgraded version of Cat 5. It is generally used in 100M networks and supports gigabit in short distances.

2) Cat6 network cables. The network cable generally has the logo of Cat.6, the frequency bandwidth is 250MHZ, and the transmission rate is 1000Mbps. Cat6 network cable is a standard gigabit network cable. Compared with Cat 5e cable, the performance has been dramatically improved because the inner copper core wire diameter is thicker, and across the frame is added in the middle to isolate four pairs of twisted pairs effectively. Crosstalk is reduced.

3) Cat6e network cable,. The network cable generally has the logo of Cat.6A, the frequency bandwidth is 500MHz, and the transmission rate is 10Gbps. The performance is more robust than that of Category 6 network cables, and it is a 10 Gigabit network cable.

4) Cat7 network cable. There is generally a Cat7 logo on the network cable. The frequency bandwidth is 600MHZ, and the transmission rate is 10Gbps. The seven-category network cable is a double-shielded network cable with double-layer shielding of aluminum foil and aluminum-magnesium wire, and it is also a 10 Gigabit network cable.

5) Cat8 network cable. The network cable generally has the Cat8 logo, the frequency bandwidth is 2000MHZ, and the transmission rate is 40Gbps. It is a relatively high-level network cable and is generally used in high-speed broadband environments.

cable quality

Network cables generally include aluminum wire, copper-clad aluminum, and pure copper wire. When choosing a network cable, you should also pay attention to the wire core material of the network cable. The best quality is copper core wire, suitable for POE power supply and has strong continuity. When testing the network cable, you can test the network cable in an environment of 35°C to 40°C to see if the rubber of the network cable becomes soft.

As can be seen from the above, different network cables support different transmission rates and frequency bandwidths, and different wire core materials will also affect network speed transmission. Choose the network cable according to the broadband, choose the super five network cables for 100M broadband, and choose the six network cables for gigabit broadband. It is best to choose pure copper or copper-clad aluminum materials at a favorable price.
