Phihong Power over Ethernet (PoE) Midspan Injectors
Power your network devices with one Ethernet cable. Phihong Power over Ethernet (PoE) and PoE midspan injectors deliver reliable power and data together, so installs are faster, cleaner, and easier to scale.
Why choose Phihong PoE?
Phihong is a trusted maker of high quality adapters and powering gear used worldwide. Their PoE midspans are built for long life, steady power, and simple setup. You get models that support IEEE 802.3af (up to ~15.4W), 802.3at PoE+ (up to ~30W), and 802.3bt (up to 60–90W, Type 3/4), so you can run everything from a basic VoIP phone to power-hungry PTZ cameras and access points.
- Standards compliant: 802.3af/at/bt with gigabit pass-through for high data rates.
- Right sized options: Single port units for small jobs, multi-port and rack mount for larger builds.
- Built in protection: Over current, short-circuit, and surge protection help keep gear safe.
- Clear status LEDs: Quick checks for power and link so you can troubleshoot fast.
- Flexible mounting: Desktop, wall mount, and 19″ rack solutions to fit your space.

What is a PoE “midspan” injector?
A PoE midspan sits between your switch and your device. It adds power onto the Ethernet line while passing data through. This is helpful when your existing switch is non PoE, or when you want to keep power and switching functions separate for easier upgrades or maintenance.
Common uses for PoE / PoE midspans
- IP cameras & security: Fixed and PTZ cams, NVR deployments, perimeter coverage.
- WiFi access points: Office, retail, school, and hospitality networks.
- VoIP phones & consoles: Power phones without desktop bricks or extra cabling.
- Industrial & IoT: Sensors, gateways, and controllers in harsh or remote spots.
- Displays & kiosks: Digital signage and info stands with one clean cable run.
How to choose the right Phihong PoE midspan
- Check device power needs. Look at wattage and standard. 802.3af (up to ~15.4W), 802.3at (up to ~30W), or 802.3bt (60–90W). Pick a midspan that meets or exceeds that number.
- Count your ports. One device? Choose a single port injector. Many devices? A multi port or rackmount model simplifies wiring.
- Confirm data speed. Use gigabit PoE if your network or devices need high throughput (most do).
- Plan the install. Desktop for quick setups, wall mount to save space, or rack mount in closets and data rooms.
- Consider environment. Check operating temperature and surge protection needs, especially for industrial or outdoor enclosures.
Compatibility & standards
Phihong PoE midspans are made to work with standards compliant devices from most major brands. If your PD (powered device) says it supports IEEE 802.3af/at/bt, a matching Phihong injector should power it. For best results, match the standard and ensure the injector’s wattage is high enough for the device at the cable length you plan to use.
Quick install tips
- Use CAT5e or better for gigabit and longer runs; keep cable quality consistent.
- Keep total cable length within 100 meters (328 ft) per Ethernet segment.
- Label ports and home run cables to make later changes painless.
- For outdoor or exposed runs, consider surge protection and shielded cable.
- Power up the injector after you’ve made your data connections to avoid surprises.
FAQ: PoE vs. PoE Midspan vs. PoE Switch
PoE is the overall technology that sends power and data over Ethernet. A PoE midspan (injector) adds power to the line while leaving your existing non PoE switch in place. A PoE switch has PoE built in. Midspans are great when you want to upgrade in steps, standardize on one power brand, or keep power separate from switching for reliability and service reasons.
