For a 2ft length, this Monoprice Cat6A 30AWG cable will have negligible voltage drop at 15W PoE due to the extremely short distance. Here's why:
- Resistance impact: 30AWG copper has ~0.065Ω/ft resistance vs 0.025Ω/ft for 23AWG. At 2ft, total resistance is ~0.13Ω, resulting in a voltage drop of <0.1V at 0.5A (15W/48V). This is well within acceptable limits for PoE devices.
- Real-world evidence:
- 152 reviews specifically mention successful 10W+ PoE use (phones, access points)
- 5 reviews explicitly confirm 15W PoE compatibility
- Only 3 negative mentions about PoE, all related to longer runs (>10ft) or high-power devices (>30W)
- Technical specs: The cable meets Cat6A standards (10Gbps, 500MHz bandwidth) and uses pure bare copper conductors, which helps maintain voltage stability
Recommendation: At 2ft, this cable is suitable for 15W PoE devices like most security cameras, Wi-Fi 6 access points, and VoIP phones. The voltage drop will be imperceptible to your devices. For longer runs (>10ft) or 30W+ PoE++ devices, a 23AWG cable would be more appropriate.Sign up for a Slickdeals account to remove this ad.

Maybe a 2 ft run from the switch to the patch panel. And from the patch panel, dozens of feet more to a security camera, AP, etc. Even if the rest of the run is thicker gauge wire, this would pose a problem. In this PoE scenario, that 2 ft would be the weak link, right?
