Protection of Ethernet Lines

With Industry 4.0, the importance of Ethernet technology is increasing every day. It is estimated that 26 billion devices will be connected to the internet in 2020. This trend is also reflected in factories. Thanks to its flexible structure and compatibility, Ethernet has spread rapidly since its inception in 1970. Starting at speeds of 3 Mbps, it now continues at gigabit speeds. The transition to gigabit Ethernet has given rise to LAN technologies and numerous communication lines. Today, Ethernet uses many types of media, from coaxial cables to twisted pair cables and fiber optics. A typical Ethernet can provide speeds ranging from 100 Mbit/s to 1000 Mbit/s. But how are Ethernet lines protected from lightning and overvoltage?

Ethernet lines can easily absorb sudden overvoltage surges.

Why Do Ethernet Lines Get Damaged?

• Sudden overvoltage or lightning strike on power, data, or telecom lines
• Electromagnetic field caused by lightning strike
• Potential differences causing surges from lightning strikes

Equalizing potential in data lines is important to protect against surges.

Protecting Ethernet Lines with Surge Protectors

Protecting Ethernet lines requires sensitive D-class protection devices. The correct product must be selected according to the type of Ethernet line. As we always emphasize, layered protection is crucial for Ethernet line protection. In the following image, you can see a real network center consisting of Ethernet, modem, ADSL, and computers being protected with surge protectors.

1- Main Panel Protection B+C class
2- 10-line Krone protection
3- Equipotential bar
4- Type 2 C class surge protector (3-phase)
5- Single-phase Type 2 surge protector Up<1500 V
6- Type 3 POE Protection Surge Protector
7- RJ11 Protection Up<250 V
8- Socket Protection Type 3
9- Data Line Protection Type 3 Up<40 V
10- Type 3 Monitoring Device Protection connected directly to socket
11- Type 2 ADSL, Modem, Twisted Pair surge protector
12- Socket protection directly protects the computer Up<100 V

Ethernet lines host many complex devices. Therefore, each device must be considered individually for protection. Since the Up protection level varies for each device, a special product must be chosen.
