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.
