48V 2A Gigabit PoE Adapter>span class=""> is a passive power injector designed to deliver both electrical power and high-speed Gigabit data to network devices over a single Ethernet cable . This is particularly useful for installations where it is not possible to place a device near an electrical outlet, such as on towers or remote network nodes .
MikroTik RBGPOE>span class=""> .
Key Features:
- Simplified Cabling: It reduces the number of cables needed by combining power and data transmission, which is a major advantage for tower or outdoor installations .
- High-Speed Connectivity: It supports full Gigabit Ethernet speeds (10/100/1000 Mbps) while providing power .
- Wide Compatibility: It is compatible with any device that accepts passive PoE within the 9-48V range .
- Passive PoE: It does not perform the "handshake" of active PoE standards (like 802.3af/at), meaning it always provides power when the input voltage is present, so the connected device must be compatible .
How it Works: You connect a DC power supply to the injector, then run a standard Ethernet cable from the injector to your target device (such as a RouterBOARD). The injector sends power over pins 4 and 5 with a return on pins 7 and 8, while data is transmitted on the other pins . An external 48V power supply is required as the injector itself does not convert AC power .
