Unmanaged Fiber Media Converter Switch, 8-Port Gigabit with 1 SC Fiber Port, 1.25Gbps, Desktop/Wall Mount for Long-Distance Network Extension

8 Gigabit RJ45 ports plus 1 SC fiber port (up to 120km). Plug-and-play, metal housing, no fan. Ideal for extending copper networks over fiber in industrial or commercial settings.

CG108
Port Description

8 x 10/100/1000Base-T RJ45 ports, 1 x 1000Base-X SC fiber port (single-mode, supports multi-mode up to 2km and single-mode up to 120km)
  • Plug-and-play deployment — no configuration required
  • Combines 8-port Gigabit switch with 1 fiber media converter in one box
  • Fiber port supports up to 120 km (single-mode) or 2 km (multi-mode)
  • Metal housing for efficient heat dissipation and long-term stability
  • 9K jumbo frame support reduces CPU overhead on bulk transfers
  • Auto-negotiation on all copper ports (10/100/1000, half/full duplex, MDI/MDI-X)
  • Fanless design – silent operation, no moving parts to fail









When Your Copper Network Hits the 100-Meter Wall

If you’ve ever tried to push a standard Ethernet run beyond 100 meters, you know the frustration: signal loss, dropped packets, and a lot of re-cabling. That’s exactly where this fiber media converter switch (CG108) steps in. It gives you eight 10/100/1000Base-T ports for local devices like IP cameras, workstations, or NVRs, plus one dedicated 1000Base-X SC fiber port that can shoot data up to 120 kilometers over single-mode fiber. No configuration, no management headaches — just plug in your fiber transceiver (or use the built-in SC port) and let the switch handle the conversion.

This unit is built for techs who need reliable, no-fuss connectivity. The metal housing acts as a passive heatsink, so it runs cool without a fan — quiet and dust-friendly for cabinets or warehouses. It supports 9K jumbo frames to cut overhead on large file transfers, and all eight copper ports auto-negotiate speed, duplex, and MDI/MDI-X. Whether you’re joining two office floors, bridging a remote security camera to the NOC, or extending a production line network across a factory yard, this device does the job with minimal maintenance.

Unlike some media converters that only offer one port in and one out, this one gives you eight copper endpoints. That means you don’t need an extra switch at the remote side — just connect your local devices directly. It’s a space-saver, a cabling-simplifier, and a cost-efficient way to merge fiber backbone with copper edge.

  • 8 x Gigabit RJ45 ports + 1 x 1.25G SC fiber port
  • Transmission distance up to 120 km (single-mode fiber)
  • Metal shell, fanless, natural cooling
  • Plug-and-play, no software needed
  • 9K jumbo frame support for better throughput
