RJ45 Passive POE Splitter Combiner uPOE Adapter Connectors 2-Pair
RJ45 Passive POE Splitter Combiner uPOE Adapter Connectors 2-Pair
2-Pair RJ45 Splitter Combiner — Passive uPOE Adapter Connectors
Expand your network without running extra cables. This 2-Pair RJ45 Splitter Combiner uPOE Adapter lets you deliver both data and power over a single CAT5e or CAT6 cable — all without replacing existing infrastructure. Perfect for IP cameras, access points, VoIP phones, and other 10/100Mbps-compatible devices, this passive POE solution is a smart, cost-effective upgrade for any home or office network.
How It Works
Standard Ethernet cables contain 8 wires, but 10/100Mbps connections only use 4 of them. This adapter cleverly utilizes the unused wire pairs (pins 4, 5, 7 & 8) inside your existing CAT5e/CAT6 cable to create a second channel — simultaneously carrying power and data to your connected devices. No new cabling required.

Frequently Asked Questions
Q: What does the RJ45 Splitter Combiner uPOE Adapter do?
A: This passive POE adapter uses the unused wire pairs (pins 4, 5, 7 & 8) in a standard CAT5e or CAT6 Ethernet cable to simultaneously carry both power and data over a single cable run. It allows you to power compatible network devices without needing a separate power cable or a managed POE switch.
Q: Is this adapter compatible with Gigabit Ethernet (1000Mbps)?
A: No — this is a passive POE adapter designed for 10/100Mbps (Fast Ethernet) networks only. Gigabit Ethernet uses all 8 wire pairs for data, leaving no spare pairs available for passive POE power delivery. It is best suited for IP cameras, VoIP phones, and similar non-Gigabit devices.
Q: Do I need any special tools or configuration to set this up?
A: Not at all. This adapter is completely plug-and-play — simply connect it inline with your existing CAT5e or CAT6 cable between your power source, switch, and end device. No drivers, software, or special tools are required.
Q: What is included in the 2-pair kit?
A: The kit includes 2 RJ45 passive POE splitter/combiner connectors — one functions as the injector (combining power + data) and the other as the splitter (separating power + data at the device end), giving you everything needed for a complete passive POE run.
