This Black Box MultiPower 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 CAT5 cable, then connect a fiber cable to an SFP installed in the converter's opposite side. The SFP slot enables you to adapt the converter to any 100-Mbps fiber interface. Best of all, you can tuck this tiny converter unobtrusively behind your PC. The converter not only links 10- and 100-Mbps segments to fiber cabling, it also works as a data rate converter, performing 10/100 autonegotiation on the twisted-pair port. For extra versatility, you can power the Miniature Media Converter one of three ways: through the external AC power supply included with each converter, through the optional USB Power Adapter Cable (LHC021A), or through the optional rackmount PowerTray (LHC018A-AC-R2).
