Passive Network power supply
POE refers to the transmission of data signals to some ip-based terminals (such as IP telephones, wireless LAN access point APS, network cameras, etc.) while the existing Ethernet CAT.5 cabling infrastructure is not changed Ethernet It also provides DC-powered technology for such devices. Poe technology can ensure the existing structure wiring security while ensuring the normal operation of the existing network, to minimize costs.
Active to use Poe SWITCH (HUB), but passive do not need?
Active only with 4 cores, 1,2,3,6. But passive should use 8 cores?
ACTIVE Poe is not necessarily a Poe SWITCH (HUB), and Poe Injetor is available! But active only support specify 4 voltage, but passive any voltage can be!
