The Lanview LVN-MED-SC-1000BASE-X-2 is a pair of unmanaged media converters for linking copper Ethernet and fiber network segments. It connects 10/100/1000Base-T over RJ45 to 1000Base-X fiber over SC connectors, providing a bridge between these two connection types.
Supplied as a pair, the converters are intended to form a link between two points. The listing specifies a fiber transmission distance of up to 20 km, useful for network links that extend beyond a short copper run.
