Frequently Asked Questions

Q: What does a PoE Splitter Combiner Cable do?

A: A PoE (Power over Ethernet) splitter combiner cable allows you to both inject power onto an Ethernet cable (combiner/injector mode) and separate the power from the data signal (splitter mode). This means you can power PoE-compatible devices like IP cameras, access points, and VoIP phones over a single Ethernet cable without needing a separate power adapter at the device end.

Q: Is this PoE cable compatible with Gigabit Ethernet speeds?

A: Yes — the Qme 9–48V PoE Splitter Combiner Cable is fully compatible with both Fast Ethernet (10/100 Mbps) and Gigabit Ethernet (10/100/1000 Mbps), so your network speed is not throttled by the power delivery component.

Q: Why is galvanic isolation important in a PoE splitter?

A: Galvanic isolation prevents unwanted electrical currents from passing between connected devices, protecting your equipment from ground loops, voltage spikes, and electrical interference. This is especially important in mixed-voltage or outdoor network installations where electrical conditions may vary.

Q: What voltage range does this PoE splitter combiner support?

A: This cable supports a wide input voltage range of 9V to 48V DC, making it compatible with a variety of passive and active PoE standards used in home, office, and professional networking environments.
