8-Port 10/100M Passive POE power supply

Model : LNK-POE-8P

Overview

The device in focus is a high-scalability 8-Port 10/100M Passive POE power supply, engineered to deliver

remote power to up to 8 terminal devices simultaneously via Ethernet wiring—extending transmission distance

to 100 meters (328 ft) while maintaining stable 10/100M data connectivity. As a dedicated 8-Port 10/100M

Passive POE power supply, it serves as a cost-effective upgrade solution to add PoE capabilities to any non-

PoE Ethernet switch or router, eliminating the need to replace existing network infrastructure and supporting

medium-scale device deployment.

This 8-Port 10/100M Passive POE power supply specializes in injecting electrical power into CAT-5, CAT-6,

or CAT-7 Ethernet cables, leveraging the mature passive PoE transmission mechanism: standard Ethernet

uses 2 of the 4 twisted pairs for data, while this device utilizes the unused 4/5 pins for positive power and 7/8

pins for ground—ensuring zero interference between power delivery and 10/100M data transmission. Each of

its 8 ports operates independently with isolated power output, providing consistent passive power to connected

devices without mutual signal disruption or cascading failures, making it ideal for scenarios requiring centralized

power for multi-device clusters.

Widely compatible with mainstream network equipment, the 8-Port 10/100M Passive POE power supply is

perfectly suited for powering IP cameras (dome, bullet, or medium-sized PTZ models), enterprise-grade IP

videophones, dual-band WiFi access points, and other passive PoE-enabled devices. Its 8-port design supports

simultaneous power supply for medium-scale setups—such as an 8-camera office building surveillance system,

a multi-zone retail WiFi network, or a classroom IP communication cluster—streamlining deployment by centralizing

the power source and reducing cable clutter.

Designed for ease of use and cost efficiency, this 8-Port 10/100M Passive POE power supply supports plug-and-

play operation with no software configuration required. It eliminates the need for 8 separate power adapters and

extra electrical wiring, drastically cutting material costs and on-site installation manpower. Whether deployed in

small-to-medium enterprises, residential communities, or chain retail stores, it combines 10/100M data compatibility,

8-device power capacity, and passive PoE reliability to offer a flexible, budget-friendly solution for extending power

and network connectivity to distributed edge devices.

Features

► Panel 8 integrating passive POE injector suitable for powering up to eight devices.

► The RJ45 connectors on one side are connected Ethernet ports with no power (switch) on the opposite side of the device used to connect power for Ethernet cable.

► Are used to power the two unused pairs of the Ethernet cable

► Power couples: 4.5 (positive pole) / 7.8 (negative pole)
