2-Group POE Adapter Injector

Model : LNK-PJ202/LNK-PJ302

Overview

PoE (Power over Ethernet) is a cutting-edge technology that transmits both data and electricity via

a single Ethernet cable, and the 2-Group POE Adapter Injector serves as a key PSE (Power Sourcing

Equipment) component in such systems—bridging power supply and data connectivity for distributed

network setups. A complete PoE system consists of PSE (like the 2-Group POE Adapter Injector) and PD

(Powered Devices such as IP cameras or wireless APs), with the 2-Group POE Adapter Injector featuring

two independent functional groups to support simultaneous power-data transmission for dual PD clusters.

This 2-Group POE Adapter Injector leverages two idle twisted pairs among the four in Ethernet cables to

transfer electricity while synchronizing Ethernet data transmission—eliminating the need for additional power

cabling. Each group of the 2-Group POE Adapter Injector operates independently, ensuring stable power

delivery and data transfer for its connected PDs without mutual interference, making it ideal for rigorous

network environments where power wiring is difficult (e.g., ceiling-mounted equipment or outdoor deployments).

As a dedicated PSE, the 2-Group POE Adapter Injector provides an effective centralized power supply solution

for IP network and WLAN wireless broadband equipment deployment. It is perfectly suited for scenarios like IP

monitoring (powering dual sets of dome/bullet cameras) and wireless access (supporting two 802.11ac/ax access

points), streamlining multi-device setup without the hassle of separate power adapters. Compared to single-group

injectors, the 2-Group POE Adapter Injector doubles deployment efficiency while retaining cost advantages—

reducing material expenses for cables and on-site installation manpower.

Extending PoE’s value, the 2-Group POE Adapter Injector aligns with PoE+ technology advantages to deliver a

cost-beneficial "last-100-meter" broadband network solution. It supports transmission of various data via the

network and is widely applicable in networking scenarios including residential communities (powering corridor

APs and entrance cameras), schools (connecting classroom IP phones and surveillance devices), hotels (linking

lobby wireless points and security cameras), and office buildings (supporting workstation thin clients). With its dual

-group design, seamless integration with PoE ecosystems, and versatile applicability, the 2-Group POE Adapter

Injector enhances the practicality of PoE technology in multi-device network deployments.
