Easily convert between copper and fiber segments in harsh environments with the Black Box Hardened Mini Industrial Media Converters. Housed in an industrial-strength housing, the rugged 2-port (1-to-1) devices are particularly ideal for any factory application where you need unmanaged conversion between a legacy 10 or 100 Mbps copper segment and a fiber backbone or other optical cable segment. Use them in power plants, mining, and military sites, or anywhere temperature and contaminants would normally wreak havoc on conversion circuitry. Manufacturer: Black Box Corporation.
