PoE Injectors are the concept of injecting Power over Ethernet into LAN networking over twisted pair cabling (Cat-5, Cat-5e, Cat-6, Cat‑7).
The IEEE specifications for Power over Ethernet 802.3af and 802.3at is limited to the maximum cable segment length to 100 meters (328 ft).
Just ask any electrician how far you can run DC power over copper – a hell of a lot further than false IEEE PoE distance limits.
PoE Injectors typically leverage 1-pair wiring or more to easily exceed the 100 meters (328 ft) distance barrier for the purpose of a remote LAN Network.
