Unmanaged Fiber Optic to Ethernet Media Converter, 4 Gigabit RJ45 + 4 SC Fiber Ports, 1.25Gbps, Plug-and-Play, Desktop/Wall Mount for Industrial & Commercial Networks

4-port fiber optic to ethernet media converter with 4x 1.25G SC fiber and 4x 10/100/1000M RJ45 ports. Plug-and-play, metal housing, extends network up to 120km. Ideal for surveillance, campus, and factory setups.

CG404
Port Description

4 x 10/100/1000Base-T RJ45 Ethernet ports (auto-negotiation, auto-MDI/MDI-X) + 4 x 1000Base-X SC fiber ports (1.25Gbps, single-mode/multi-mode, distance up to 120km).
  • 4 Gigabit copper ports + 4 1.25G fiber ports – true plug-and-play fiber optic to ethernet media converter.
  • Store-and-forward switching with 16Gbps backplane; wire-speed forwarding keeps latency low.
  • Jumbo frame support up to 10K bytes for efficient large-packet transport.
  • Metal housing with fanless natural cooling; operates reliably from -20°C to +60°C.
  • Auto-negotiation and auto-MDI/MDI-X on all RJ45 ports – no crossover cable worries.
  • Power consumption under 3 watts – ideal for low-budget, always-on deployments.









Extend Your Network Beyond 100 Meters – No Configuration Needed

When your twisted-pair copper cable runs hit the 100-meter limit, the CG404 fiber optic to ethernet media converter steps in to bridge that gap. This compact unit blends four 10/100/1000Base-T Ethernet ports with four 1000Base-X SC fiber ports, giving you a straightforward way to connect copper devices to a long-distance fiber backbone. It’s not a complex managed switch – it’s a workhorse that does one thing well: convert and forward traffic without any setup fuss.

The metal casing pulls heat away naturally (no fan noise), so you can tuck it into a cramped wiring closet or mount it on a wall next to a security camera rack. With support for jumbo frames up to 10K bytes, it handles large data packets like video streams or backup transfers more efficiently. All Ethernet ports auto-negotiate speed and duplex, plus they auto-crossover, so you can use straight or crossover cables interchangeably – a small but real time-saver when you’re patching cables in the field.

For IT administrators managing distributed office networks, security integrators running IP cameras over long distances, or facility engineers linking remote buildings, this fiber optic to ethernet media converter delivers a stable, low-maintenance link. The fiber ports are single-mode SC (SFP optional), supporting distances from 550 meters on multi-mode up to 120 kilometers on single-mode. Power draw stays under 3 watts, meaning it runs cool even in hot environments (-20°C to +60°C working temp). No web GUI, no CLI – just plug in your copper and fiber cables, and you’re live.
