Extend Your Network with a Reliable Media Converter Fiber to RJ45

When you need to bridge twisted-pair Ethernet with long-haul fiber optics, this media converter fiber to RJ45 switch does the job without any configuration. It combines eight 10/100/1000Mbps copper ports and two 1.25Gbps SFP fiber slots, letting you connect cameras, workstations, or servers across distances up to 120 kilometers. The whole setup is truly plug-and-play—just plug in your devices and the switch starts forwarding frames at wire speed.

We built this switch for IT admins who want a no-fuss solution for extending a local network beyond the 100-meter limit of copper cabling. The metal casing acts as a heatsink, so the unit stays cool even in a crowded wiring closet or on a factory floor. With support for jumbo frames up to 9K and full-duplex on all ports, you get smooth throughput for large file transfers or video surveillance streams. No VLANs, no management interface—just reliable layer-2 forwarding that keeps your network running.

Typical deployments include linking two buildings with single-mode fiber, connecting remote IP cameras back to a recording server, or providing a dedicated fiber uplink for a small office switch. Because the SFP slots accept both multi-mode and single-mode modules, you can match the exact distance and budget you need. And since the switch is unmanaged, there’s zero learning curve for anyone on your team.
