Gigabit PoE Injector IEEE802.3af 15.4W

Model : LNK-POE300


Overview

The LNK-POE300 is a high-performance Gigabit PoE Injector IEEE802.3af 15.4W, a certified midspan
engineered for long-distance power delivery, ultra-fast network transmission, and stable high-power PoE
output. As a dedicated Gigabit PoE Injector IEEE802.3af 15.4W, it strictly complies with the IEEE802.3af
standard and supports the 1000BASE-T Gigabit Ethernet protocol, enabling seamless integration with
modern high-speed network infrastructures while meeting standard PoE power supply requirements.
​
This Gigabit PoE Injector IEEE802.3af 15.4W features a single-port indoor design, capable of delivering
a stable maximum output power of 15.4W—consistent with IEEE802.3af specifications—to power a variety
of PoE-enabled edge devices. It excels in scenarios requiring both high-bandwidth data and reliable power,
making it ideal for powering 802.11 high-speed wireless access points (WAPs), HD pan-tilt-zoom (PTZ) cameras,
dome IP cameras, IP videophones, thin clients, and small IoT terminals—effectively supporting 1080p HD video
transmission and high-speed data exchange thanks to its Gigabit connectivity.
​
A core advantage of the Gigabit PoE Injector IEEE802.3af 15.4W lies in its dual reliability of performance and
safety: it fully supports IEEE802.3af-powered devices (PDs) and maintains backward compatibility with all
IEEE802.3af-compliant terminals, eliminating the risk of device damage caused by power mismatches. Built-in
protection mechanisms including overcurrent, overvoltage, and short-circuit protection further enhance deployment
security, ensuring stable long-term operation. Its plug-and-play design requires no complex software configuration—
simply connect the injector to a non-PoE Gigabit switch (via the data input port), an AC power source, and the target
device (via the PoE output port) using standard Cat.5e/6 UTP cables.
​
By leveraging existing Ethernet infrastructure to transmit both 1000Mbps Gigabit data and 15.4W PoE power simultaneously,
this injector avoids the need for additional power cabling and power outlets, significantly reducing deployment costs and
construction complexity. It supports long-distance power-data co-transmission, addressing the pain point of powering
remote devices in scenarios like small-to-medium enterprise security surveillance, office high-speed wireless coverage,
and retail smart terminal networks. With its IEEE802.3af compliance, Gigabit transmission capability, and stable 15.4W
output, the Gigabit PoE Injector IEEE802.3af 15.4W offers a cost-effective, future-proof solution for upgrading non-PoE
networks to support high-speed, power-efficient edge devices.
