4-Port PoE Injector Coming with the Ethernet network port and PoE output port

4-Port PoE Injector

Model : LNK-POE204


Overview

The 4-Port PoE Injector—also known as a Power over Ethernet mid-span device—is a high-flexibility
PoE power supply module, standing out as one of the most popular and versatile options among power
supply equipment for small-to-medium network deployments. As a dedicated 4-Port PoE Injector, it integrates
the dual function of data transmission and power injection, eliminating the need for independent power wiring
and simplifying the connection of PoE-powered devices (PDs).
This 4-Port PoE Injector is equipped with 4x RJ45 PoE output ports, paired with 4x2 standard RJ45 network
ports divided into two functional groups: one group serves as upstream ports, designed to connect to Ethernet
switches, routers, or other network core devices for data signal access; the other group functions as downstream
ports, supporting simultaneous PoE power supply and network data output to connected terminal equipment.
This port grouping design ensures seamless data transmission while delivering stable power, making the 4-Port
PoE Injector highly adaptable to diverse network topologies.
A key advantage of the 4-Port PoE Injector lies in its exceptional flexibility: it can be easily integrated with existing
non-PoE network infrastructures, allowing users to add PoE capabilities without replacing legacy switches or routers
—greatly reducing upgrade costs. It is compatible with a wide range of PDs, including IP cameras, IP phones, WiFi
access points, and small IoT gateways, with each of the 4 PoE ports providing reliable power and data co-transmission.
Ideal for scenarios like small office wireless coverage, retail store surveillance, and home smart security systems, the
4-Port PoE Injector supports plug-and-play deployment with no complex configuration required. Its compact design
saves space in network cabinets or wall-mounted installations, while the independent port operation ensures that power
or data issues on one port do not affect others. By combining mid-span device reliability, 4-port expansion capability,
and flexible deployment, the 4-Port PoE Injector becomes a cost-effective and practical solution for powering distributed 
edge devices.
