Move traffic off copper and onto fiber without redesigning the network. The Black Box FLEXPT MED CONV 10 1000BT, MPN LMC1017A-MMSC, converts 10/100/1000Base-T Ethernet to 1000Base-SX over multimode fiber, giving infrastructure teams a straightforward way to extend links beyond copper limits and reduce exposure to electrical noise. This media converter fits where a switch upgrade is unnecessary but a fiber handoff is required. The multimode SC interface supports short- to medium-reach backbone and access deployments, while gigabit copper compatibility preserves connectivity for existing endpoints, industrial devices, and edge equipment. It is a practical choice when you need to preserve installed assets and still meet fiber-based transport requirements. For environments where uptime and signal integrity matter, a dedicated media converter is often the cleaner answer than adding complexity at the switch layer. Use it to connect remote closets, bridge building segments, or transition copper-only devices into a fiber plant with minimal disruption. The result is a focused, purpose-built conversion point that supports dependable network extension without overbuying hardware.
