LANs are now used not only for PCs, but also for security systems such as ITV surveillance cameras, etc. Here, we will introduce lightning countermeasures for LANs in office internal networks.
While wireless LANs are becoming more and more popular, wired LANs are still used in some office networks from the perspective of transmission speed, radio wave conditions, and security measures. When implementing lightning protection for PCs, it is also essential to take measures for LANs. If a server or PC is damaged by lightning, there is a possibility that the data will be lost.
In addition, when buildings are connected to each other on the same site by LAN cables, there is a risk of lightning surges entering from outside and a risk of potential differences due to the long wiring length, so further measures are recommended.
