"28AWG cables cannot be used for PoE" is a useful safety warning, but not an absolute technical truth. A more precise professional statement would be: uncertified and unevaluated 28AWG cables must never be used for PoE. However, in clearly defined short‑distance, low‑power, and well‑ventilated scenarios, strictly certified 28AWG cable can serve as a space‑saving and effective solution.Our responsibility as professionals is to make decisions based on data and the manufacturer’s explicit specifications, not on a simple "yes" or "no." I have used this type of cable myself, and it works fine for short‑range PoE. I have not used it for long distances, nor would I, since this is merely one of the solutions adopted to address my space constraints.
