Move Ethernet farther without redesigning the network. This Black Box media converter supports 10/100/1000 Ethernet over single-mode fiber at 1310 nm, with reach up to 20 km. It is built for environments where copper cannot cover the distance between buildings, telecom rooms, or remote equipment locations. For infrastructure teams, the value is in preserving link integrity while extending service to the edge. A dedicated media converter avoids the compromises of improvised uplink paths and gives you a clean transition between copper Ethernet and fiber transport. That matters when you are connecting surveillance systems, remote closets, industrial endpoints, or campus segments that need dependable transport over longer spans. The result is a practical, purpose-built network bridge that supports stable deployment planning. Instead of overprovisioning switches or running new copper pathways, teams can place fiber where it belongs and keep Ethernet service consistent end to end. For projects where uptime, distance, and signal quality all matter, this model delivers the right balance of reach and simplicity.
