Product Details
| Feature | Description |
| Simplicity | They are very simple, low-cost devices with minimal circuitry. |
| Non-Standard | They are not compliant with IEEE PoE standards (802.3 af/at/bt). |
| Voltage | The voltage must match the remote device’s power requirements exactly, as there is no voltage regulation or negotiation. Using the wrong voltage can permanently damage the connected device. |
| Safety | They lack the “handshake” and power detection features of standard PoE, meaning power is applied to the cable constantly, which can be a risk if a non-PoE device or a person comes into contact with the energized cable’s pins. |
| Use Case | Typically used for low-power 10/100 Mbps devices where a simple, budget-friendly power solution is needed and distances are relatively short (to minimize voltage drop). |
| 1000 Mbps Limit | Passive PoE using spare pairs is not compatible with Gigabit (1000 Mbps) Ethernet, as Gigabit uses all four pairs for data. |
