This article covers Zyxel シングルポートマルチギグインジェクター.

Overview

The Zyxel POE12-90W is a single-port PoE++ injector that delivers up to 90W of power over a single Ethernet cable, compliant with IEEE 802.3bt (Type 4). It supports multi-gigabit speeds up to 10 Gbps, making it ideal for powering high-demand devices like Wi-Fi 6/6E access points, outdoor IP cameras, and IP phones that exceed the 30W limit of standard PoE+. Designed for professional and prosumer use, this injector lets you add PoE capability to any non-PoE switch without replacing the entire network infrastructure. It features a compact, direct-plug design with an integrated power supply, so it doesn't take up extra desk or rack space.

Connectivity & Compatibility

The POE12-90W has two RJ-45 ports: one data input (10G capable) and one PoE++ output (also 10G capable). Simply connect your switch or router to the input port, and the powered device to the output port. It automatically negotiates power delivery with any 802.3af/at/bt compatible device, stepping down to 15.4W or 30W as needed. It works with any standard PoE-powered device, including wireless access points, IP cameras, VoIP phones, and IoT gateways. The 10Gbps link ensures no speed bottleneck even with the latest high-bandwidth equipment. Non-PoE devices cannot be powered by this injector; they would still need their own power source.

Product Info

The Zyxel POE12-90W (model POE12-90W) was released in 2024 and sits in the mid-to-high-end segment of the PoE injector market. It's aimed at users who need reliable, high-power PoE delivery without investing in a full PoE switch. The street price in Japan is around ¥42,748 (as of June 2025). The package includes the injector and a power cord; Ethernet cables are not included. The manufacturer offers a standard 2-year warranty.

Best Use Cases

Small businesses deploying Wi-Fi 6/6E access points: If you have a non-PoE switch and only need to power one or two APs, the POE12-90W is a cost-effective alternative to upgrading to a PoE switch. It delivers the full 90W needed by high-performance APs. Outdoor or remote camera installations: IP cameras with heaters or pan/tilt/zoom mechanisms often require more than 30W. This injector lets you run a single Ethernet cable to the camera, simplifying wiring and eliminating the need for a separate power outlet at the camera location. * 10Gbps network upgrades: For users building a 10G LAN, many 10G-capable access points and cameras require PoE++ to operate at full speed. This injector provides both the bandwidth and the power in one cable, preserving the 10G link. If your powered devices consume only 15–30W, a cheaper PoE+ injector will suffice. For installations with many PoE devices, a PoE switch may be more convenient and cost-effective than multiple injectors.
