STG STG-SW-POE-3-110 PoE Switch / Extender, 2 Θύρες PoE + 1 Uplink, 10/100 Mbit/s

Running network cables to remote corners of a building often means facing a frustrating dilemma: either pull separate power lines or compromise on device placement. The STG-SW-POE-3-110 eliminates that trade-off by merging switching and Power over Ethernet into a single compact unit. With two PoE output ports and one uplink, it delivers both data and electricity over a single Ethernet cable, simplifying installations of IP cameras, wireless access points, VoIP phones, and other PoE-powered equipment. No extra power sockets? No problem.

Who is it for

This extender is built for installers, integrators, and IT professionals who need to place network devices in locations where power outlets are scarce or impractical. It is equally useful for extending network reach within a building when the distance between the main switch and the end device exceeds the standard 100-meter Ethernet limit. Surveillance systems, warehouse Wi-Fi coverage, and remote sensor networks are typical applications.

Main features

• 2 x 10/100 Mbps PoE output ports plus 1 x uplink port for seamless connection to your existing network.
• Complies with IEEE 802.3af/at Power over Ethernet, delivering up to 30 watts per port to power demanding devices.
• Extends PoE transmission distance to 250 meters in Extended Mode, giving you greater placement flexibility.
• Plug and play design – no complicated configuration, set it up in minutes.
• Fanless metal housing ensures quiet operation and sturdy protection for continuous use.
• Versatile power options: can be powered via the uplink PoE input or an external DC adapter (48-57V).

Tips

To maximize the extended mode range, use high-quality Cat5e or Cat6 cables and ensure the connected PoE devices support the lower data rate when operating beyond 100 meters. When powering the switch via PoE from the uplink, confirm that the upstream PSE can supply sufficient power for both the switch itself and the connected PoE devices.
