Bridge copper and fiber with a media converter designed for long-reach Ethernet transport. The AddOn Networks ADD-GMC-LX-LC converts 10/100/1000BASE-TX traffic on RJ-45 to 1000BASE-LX over LC single-mode fiber, giving network teams a direct path from copper endpoints into fiber backbones. With support for 1,310 nm single-mode transmission and distances up to 10 km, it is well suited to campus links, building interconnects, and other deployments where standard copper cannot reach. That makes it a practical choice when you need stable, standards-based conversion rather than a temporary workaround. This model fits environments that value predictable link behavior, clean handoff between media types, and the ability to extend Gigabit Ethernet without redesigning the access layer. For teams comparing options, the difference is in the reach and the precision of the conversion: a focused device for a specific network problem, not a general-purpose substitute.
