Unmanaged PoE Powered Switch 4 Port Gigabit with 2 SC Fiber Ports, Reverse PoE Input/Output, for Remote Power Extension

4-port gigabit PoE powered switch with reverse PoE input (3 ports) and output (1 port), plus 2 SC fiber uplinks. Solves remote device powering without extra wiring — plug and play, no settings needed.

SG204RP
Port Description

4 x RJ45 10/100/1000M (ports 1-3 support PoE input 9-52V, port 4 supports PoE output 9-52V) + 2 x SC 1.25G fiber ports
  • Reverse PoE architecture: take power from any of 3 input ports, deliver it out via the 4th port or DC socket
  • Two independent 1.25G SC fiber uplinks for long-haul connections up to 100km
  • One-button switch for VLAN isolation mode or 250m extended distance (10M forced)
  • 9K jumbo frame support improves data transfer efficiency
  • True plug-and-play — no IP setup, no management software
  • Ultra-low power consumption (<3W) keeps operating costs minimal









Power your remote devices without pulling extra cables

Deploying IP cameras, access points, or sensors in areas without local power outlets has always been a headache. This 4-port gigabit PoE powered switch (model SG204RP) flips the problem: it takes PoE power in on three of its RJ45 ports (9-52V) and then delivers that power out through the fourth port, plus a dedicated 12V/1A DC socket. That means you can run the whole unit from a single PoE source, or daisy-chain power to another device down the line — no need to run separate power wires or install extra AC outlets.

Built for IT admins and network installers who work in warehouses, parking lots, or industrial floors where running new power is costly, the switch is truly set-and-forget. Both fiber SC ports run at 1.25G, letting you extend the network up to 100km over single-mode fiber. And with the one-button toggle for VLAN isolation or 250m long-distance mode (forcing 10M speed), you can adapt to tricky cable runs without swapping hardware.

Key highlights for your next deployment:

  • 4 x 10/100/1000Base-T RJ45 (3 PoE input, 1 PoE output) — all auto-negotiating and MDI/MDI-X
  • 2 x 1.25G SC fiber ports (single-mode, multi-mode options available)
  • 9K jumbo frame support for better throughput
  • Low power draw under 3W — easy on your UPS budget
  • No software configuration, just plug in and link up

Whether you’re setting up a temporary surveillance system or extending network to a far corner of a factory, this PoE powered switch handles the power chain so you don’t have to. Its compact PCBA board (84x58x15mm) fits into enclosures or junction boxes. Just make sure your source provides at least 9V PoE (passive or standard), and you’re good to go.
