His item is an 8-port Reverse Power over Ethernet (PoE) Switch, designed for networking in scenarios like FTTH (Fiber to the Home) where a centralized power source is not readily available for the switch itself.
Reverse PoE Technology: The switch is powered by the connected network devices (such as ONUs) via the RJ45 ports rather than a traditional AC power adapter.
Port Configuration: Features 8 ports for reverse power input and data transmission, typically offering 10/100 Mbps or Gigabit speeds.
