Keep 10/100 Ethernet segments in service when copper distance or EMI becomes a constraint. The Black Box LMC100A-SC-R3 media converter translates 10/100Base-TX RJ-45 traffic to multimode fiber, helping you extend network reach while preserving existing switches, controllers, and attached devices. Built for straightforward copper-to-fiber conversion, this unit fits cleanly into mixed infrastructure where a full network refresh is not justified. It is a focused solution for extending access links, connecting remote equipment, or bridging electrically noisy areas where copper alone is not the right medium. For teams maintaining older but still critical network assets, the value is in precision: convert only what needs converting, keep the rest of the stack intact, and avoid unnecessary replacement costs. Black Box positions this converter for environments that need dependable media translation rather than extra complexity.
