Bring fiber to the desktop more conveniently and at a lower cost than installing fiber NICs. This single-strand fiber media converter enables you to make two Ethernet connections over a duplex fiber cable, so you need to run less fiber. Black Box Miniature Media Converters make it easy to bring fiber to the desktop. Just connect a Miniature Media Converter to your PC's copper port with a CAT5 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. This single-mode duplex fiber converter supports distances of up to 40 kilometers (24.8 mi.). For extra versatility, you can power the Miniature Media Converter through the external AC power supply included with each converter or through the optional rackmount PowerTray (sold separately).
