How do you extend POE to 600 meters while keeps bandwidth of 100Mbps?

Generally, the transmission distance of a POE network is limited to 100 meters. Up to 90w power is delivered to the PD terminal through lan cables. In some installation conditions, the transmission distance of POE is required to extend to 300m or even 500m or 600m. To solve the engineers' problems, we POEPLUS developed a maximum 800m extender at 100Mbps.

EX101LDP-T/R are poe extender work in pair，allow max 500m POE transmission between the pair. Remarkably, the bandwidth remains at 100Mbps over such a long transmission distance.
