Black Box Multi-Power Miniature Media Converter - fiber media converter - 100 Mbps

Black Box Multi-Power Miniature Media Converter makes it easy to bring fiber to the desktop. Just connect a Miniature Media Converter to your PC's copper port with a Cat 5 cable, then connect a fiber cable to the converter's other side. That's all there is to it! Best of all, you can tuck these tiny converters unobtrusively behind your PC. The converter not only links 10- and 100-Mbps segments to fiber cabling, they also works as data rate converters, performing 10/100 auto-negotiation on the twisted-pair port.
