Power-over-Ethernet begins with a CAT5 “Injector” that inserts a DC Voltage onto the CAT5 cable.
Some Wireless Access Points and other network accept the injected DC power directly from the CAT5 cable through their RJ45 jack.
These devices are considered to be “PoE-Compatible” or “Active Ethernet Compatible”.
Can I use cat5 for PoE?
Power over Ethernet requires a CAT 5 injector, a power source that will travel through the unused wires in the CAT 5 Cable. Some devices are able to accept the power directly from the CAT 5 Cable through the RJ45 jack. These type of devices are called “PoE Compatible” (or “Active Ethernet Compatible”).
Do I need special CAT 5 cable for PoE?
POE requires special wiring. Not at all, the same cabling – Cat 5e, Cat 6, etc – and “RJ45”-style connectors are used for both regular and PoE-enabled local area networks. Power is forced into devices.
What kind of cable do I need for PoE?
Ethernet cable that meets CAT5e (or better) standards consists of four twisted pairs of cable, and PoE sends power over these pairs to PoE-enabled devices.
Can an Ethernet cable be used for PoE?
In fact, Power over Ethernet, or PoE, will work with existing cable, including Category 3, 5, 5e or 6.
