You didn't say how far the fiber run is, but if it's not too far you can easily run 100Mbps full duplex ethernet between a pair of switches. If your switches don't have fiber ports then you need a pair of media converters to convert 100 BaseFX to 100 BaseTX. FX is fiber, TX is copper. Put one at each end between the switch and the fiber. You can find these at DataComm Warehouse (warehouse.com) or probably any number of other vendors. 62.5/125 is your garden variety multi-mode fiber. Make sure your media converters are spec'd for that fiber type. There are others. -Mitch To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
