Extend power and data over one cable when the switch does not provide native PoE. The TP-Link POE160S is a compact PoE injector designed for focused deployments that need a clean, cost-conscious way to power a compatible device without reworking the access layer. It is a strong fit for retrofits, isolated endpoints, and small installations where adding a full PoE switch would be more hardware than the job requires. For infrastructure teams, the appeal is straightforward: preserve the existing network path, add PoE at the edge, and avoid unnecessary switch replacement. Gigabit Ethernet support keeps the data path aligned with modern endpoint requirements, while IEEE 802.3af/at compatibility broadens device support across common powered hardware. This is the kind of accessory that earns its place in the rack or on the desk by solving a specific problem cleanly. Instead of overprovisioning an entire switch for one or two powered devices, the POE160S gives you a direct, targeted power injection point. That makes it a practical choice for branch upgrades, temporary installs, and environments where uptime and simplicity matter more than adding another managed switch to the stack.
