Surge protector for 10Gb Ethernet (Cat6A, RJ45)

MJ8-C6A is a replacement product for MJ8-CAT6S


MJ8-C6A Ethernet network surge protectors are designed for computer networks with very fast data transfer speeds up to 10 Gbit/s for the Category 6A networks with shielded cable (STP). Featured with in/out RJ45 connectors.

Their GDT/Diodes circuit gives them the discharge capacity necessary for the protection of inter-building connections. In order to cover the many various types of networking applications

The surge protector for IT networks must be installed while respecting the following principles:
  • SPDs must be installed on the both sides of the transmission line (e.g. server side and terminal equipment side)
  • The surge protector and the protected equipment must be interconnected with the bonding network of the installation.
  • The earthing conductor (between the earth output of the SPD and the bonding circuit of the installation) must be as short as possible (less than 0.50 m).
  • The AC power supply of the equipment must also be surge protected.
