1-Port Gigabit PoE Midspan Injector B Mode 90W | Qme

Power your network devices effortlessly with the 1-Port Gigabit PoE Midspan Injector – B Mode, 90W. This high-performance Power over Ethernet (PoE) injector delivers up to 90 watts of reliable power through a single Gigabit Ethernet port, eliminating the need for separate power adapters on compatible devices like IP cameras, wireless access points, VoIP phones, and more.

Designed for seamless integration into both home and professional network setups, this midspan injector operates in B Mode, using spare pairs (pins 4/5 and 7/8) to carry power — making it ideal for devices that require alternative power delivery configurations. With full Gigabit (10/100/1000 Mbps) data throughput, you won't experience any reduction in network speed while powering your devices simultaneously.

Frequently Asked Questions

Q: What is a PoE Midspan Injector and how does the Gigabit 90W B Mode version work?

A: A PoE (Power over Ethernet) midspan injector sits between your existing network switch and a PoE-compatible device, adding electrical power to the Ethernet cable so you don't need a separate power outlet at the device end. This 90W Gigabit B Mode injector uses spare wire pairs (pins 4/5 and 7/8) to deliver power — making it compatible with B-mode PoE devices — while simultaneously passing full Gigabit data at 10/100/1000 Mbps.

Q: What devices can I power with this 90W PoE Injector?

A: With 90 watts of output, this injector can power a wide range of demanding network devices including PTZ (pan-tilt-zoom) IP cameras, enterprise-grade wireless access points, VoIP phones, network switches, and other high-power PoE-compatible equipment. Always verify that your device supports B Mode PoE input before connecting.

Q: Do I need to replace my existing network switch to use this PoE injector?

A: No. That's one of the key advantages of a midspan injector. It works with your existing non-PoE switch — simply connect your switch to the injector's data-in port, and your PoE device to the injector's output port. No switch replacement or configuration changes are needed, making it a cost-effective upgrade to your current network setup.

Q: Is this PoE injector compatible with IEEE 802.3bt or other PoE standards?

A: This unit is designed as a B Mode midspan injector delivering up to 90W. For precise standard compatibility (e.g., 802.3bt), please refer to the product datasheet or contact Qme directly to confirm compatibility with your specific device before purchasing.
