FAQ
What type of PoE does the TL-POE4818G support?
The TL-POE4818G supports passive PoE, which delivers constant 48V DC power without negotiation. This differs from IEEE 802.3af/at/bt standards that include handshaking protocols. Passive PoE is compatible with specific devices designed for this power delivery method, such as certain TP-Link access points and cameras.
What devices are compatible with this PoE injector?
This injector is specifically compatible with TP-Link's passive PoE products, including the Omada EAP245 V4.0, EAP225 V5.0, and EAP650-Outdoor V1.0 access points. It may work with other passive PoE devices that accept 48V DC power, but compatibility should be verified with the device manufacturer before deployment.
What is the maximum distance for power and data transmission?
The TL-POE4818G can deliver both power and data up to 100 meters (approximately 328 feet) using standard Ethernet cabling. This distance allows for flexible device placement in large areas while maintaining network connectivity and power delivery through a single cable run.
Does this injector require any configuration or software?
No configuration or software is required. The TL-POE4818G operates as a plug-and-play device.
