Three-port PoE switch

A 3-port PoE switch provides data and power over Ethernet to small networks, supporting IEEE 802.3af/at standards with up to 30W per port.Key FeaturesPorts and Speed: Typically includes 3 Gigabit RJ45 ports, with one PoE input port and two PoE output ports, supporting 10/100/1000 Mbps auto-negotiation for high-speed data transfer (TP-SW3G example) .PoE Standards: Supports IEEE 802.3af (PoE) and IEEE 802.3at (PoE+) standards, allowing devices like IP cameras, wireless access points, and VoIP phones to receive power directly through Ethernet cables .Power Output: Each output port can deliver up to 30W, with some models capable of up to 60W total power, depending on the switch design .Plug-and-Play: Many 3-port PoE switches are unmanaged and require no configuration. They automatically detect connected devices and provide power safely, making installation simple .Power Options: Some switches can be powered via PoE input or an external DC adapter, offering flexibility for locations without direct power outlets .Distance and Connectivity: PoE output ports typically support up to 100 meters (330 feet) of Ethernet cable, and multiple switches can be daisy-chained to extend network coverage up to 300 meters .Durability: Many models feature metal cases, surge protection, and conformal coating for moisture resistance, suitable for industrial or outdoor environments .Use CasesSmall Office or Home Networks: Ideal for connecting a few PoE devices without needing a larger switch.IP Cameras: Provides both power and data to security cameras in locations without nearby power outlets.Wireless Access Points: Powers APs in ceilings or walls where AC power is unavailable.VoIP Phones: Simplifies deployment by eliminating separate power adapters.Example ModelsTP-SW3G: 3-port Gigabit PoE switch/extender, supports IEEE 802.3af/at, up to 30W per port, plug-and-play, compatible with Cat5 or higher cables .MokerLink 3-Port PoE Extender: Includes 1 PoE input and 2 PoE output ports, supports up to 30W per port, can function as a PoE switch, extender, or network extender depending on power supply .PoE Splitter 1-in-3-out: Expands a single PoE port into three outputs, delivering up to 30W per port, ideal for adding multiple devices without extra wiring . These compact 3-port PoE switches are versatile, energy-efficient, and suitable for small-scale deployments where both power and data need to be delivered over Ethernet.
