Lantronix C4120-1048 ION 10 Gigabit Ethernet Media Converter Module, 10GBase-T 100 to 10GBase-X SFP+ Slot (Empty)

Built for high-performance security, surveillance and data center networking, the Lantronix C4120-1048 media converter delivers a simple way to bridge 10G copper and fiber links. This compact module converts a 10GBase-T RJ-45 copper port to an open 10GBase-X SFP+ slot, enabling you to swap media types without replacing existing switches. The SFP+ expansion supports a wide range of 10GE SFP+ transceivers and direct attach copper (DAC) cables, giving IT teams the flexibility to choose fiber or short-range copper for monitoring and security devices.

Ideal for surveillance camera backbones, access control systems, and high-density data center racks, the C4120-1048 reduces rack clutter and extends network reach while maintaining full 10 Gigabit Ethernet performance. Its plug-and-play operation and broad module compatibility simplify deployments and speed upgrades. Backed by Lantronix reliability and a lifetime limited warranty, this media converter is a practical choice for mission-critical monitoring and networking applications. Add the C4120-1048 to your next security or data center deployment to quickly convert media and optimize link performance.
