The LNK-POE300AT is a high-performance Gigabit PoE Injector IEEE802.3at 30W, an IEEE802.3af/at
dual-certified midspan engineered for long-distance power delivery, ultra-fast gigabit network transmission,
and robust PoE output capability. As a dedicated Gigabit PoE Injector IEEE802.3at 30W, it prioritizes
compliance with IEEE802.3at (PoE+) standards—delivering enhanced power while retaining compatibility
with IEEE802.3af devices—and supports 10/100/1000Mbps adaptive Ethernet transmission, seamlessly
integrating with modern high-bandwidth network infrastructures.
This Gigabit PoE Injector IEEE802.3at 30W features a single indoor port design, capable of supplying a
stable maximum output power of 30W—meeting the elevated power demands of PoE+ powered devices
(PDs) that require more than the 15.4W limit of basic PoE. It is ideally suited for powering power-hungry
terminal equipment, including 802.11ax high-bandwidth wireless access points (WAPs), pan-tilt-zoom
(PTZ) cameras with infrared night vision and AI analytics, dome IP cameras with 4K video recording, IP
videophones with touchscreen displays, industrial thin clients, and multi-sensor IoT gateways—ensuring
consistent operation even in data- and power-intensive scenarios.
A core advantage of the Gigabit PoE Injector IEEE802.3at 30W lies in its broad compatibility and robust
safety: it fully supports IEEE802.3af/at PDs and maintains backward compatibility with all IEEE802.3af/at-
compliant terminals, eliminating risks of device damage from power mismatches. Built-in protective mechanisms
—including overcurrent, overvoltage, short-circuit, and over-temperature protection—further enhance deployment
reliability, making it suitable for long-term 24/7 operation. Its plug-and-play installation requires no software
configuration: simply connect the injector to a non-PoE gigabit switch (via the data input port) and an AC power
source, then link the output port to the target device via standard Cat.5e/6 UTP cable. This leverages existing
Ethernet cabling to transmit both gigabit data and 30W power simultaneously, avoiding costly additional power
wiring and simplifying deployment.
Engineered for practicality, this injector excels in long-distance power-data co-transmission (up to 100 meters
via standard cabling), addressing the challenge of powering remote edge devices in scenarios like medium-sized
security surveillance systems, enterprise-grade wireless coverage networks, and smart retail deployments. With its
IEEE802.3at compliance, stable 30W output, and gigabit transmission capability, the Gigabit PoE Injector IEEE802.3at
30W offers a cost-effective, future-proof solution for upgrading non-PoE networks to support high-performance PoE+
devices.
