The LINOVISION 4 Ports Gigabit PoE Passthrough Switch and PoE Extender is designed to simplify network expansion in environments where power outlets are limited. This unit operates as both a switch and a repeater, accepting a single 90W PoE++ input and distributing it across four Gigabit ports while maintaining stable data transmission. The enclosure is constructed from durable metal, providing effective heat dissipation and long-term reliability in both indoor and semi-outdoor settings. The hardware supports IEEE 802.3af/at/bt standards, ensuring broad compatibility with a variety of powered devices such as IP cameras, VoIP phones, and wireless access points. From a performance perspective, each of the four ports delivers up to 30W per port (total 90W input), allowing simultaneous power and data delivery over a single Ethernet cable.

The passthrough capability extends the original PoE range by up to 100 meters, eliminating the need for additional power adapters at intermediate points. The switch operates silently with no moving parts, making it suitable for noise-sensitive areas like offices or recording studios. The built-in surge protection helps safeguard connected equipment against voltage fluctuations, contributing to stable operation over extended periods. The build quality reflects careful engineering: the metal housing is both lightweight and sturdy, with mounting brackets included for wall or rack installation.

The LED indicators clearly display power and link status, simplifying troubleshooting. The device runs cool even under full load, maintaining consistent throughput without thermal throttling. With a compact footprint, it integrates easily into existing network setups without occupying excessive space. The included power supply unit is rated to handle the full 90W input, ensuring sufficient headroom for high-power devices like PTZ cameras or multi-band access points.

Versatility is a key attribute of this PoE extender. It supports both PD (Powered Device) and PSE (Power Sourcing Equipment) modes, allowing it to function as a range extender for existing PoE networks or as a standalone switch when connected to a PoE++ injector. The plug-and-play design requires no configuration, enabling immediate deployment in environments such as retail stores, warehouses, or residential properties. The switch is compliant with international safety and electromagnetic compatibility standards, adding an extra layer of assurance for continuous-duty applications.

Affordability is another standout feature. At a price point that represents strong value, this unit offers a cost-effective solution for expanding PoE networks without investing in additional infrastructure. The combination of gigabit throughput, high power output, and durable construction makes it a practical choice for budget-conscious installations that still demand reliable performance. For users looking to extend their PoE reach or add multiple powered devices in a single location, this switch provides a straightforward and efficient answer.
