Installation Sheet

The MJ8-POE-C6A is designed to protect sensitive data-processing equipment connected to a POE++ (Power over Ethernet) network from transient overvoltages. This SPD is qualified with the maximum transmission speed and cabling category used for these Ethernet networks: 10Gigabit Ethernet and Category 6A. Obviously, it is applicable for the Ethernet networks with lower categories. The MJ8-POE-C6A surge protector is deployed in signal network applications with data transmission speeds of 100 and 1000 Mbps. The surge protector is housed in a shielded enclosure with high quality RJ45 shielded jacks. The transient protection circuit is based on high energy gas discharge tubes (GDT) and a network of fast response silicon avalanche diodes (SAD) to achieve sharp clamping of very large surge events.
