This is a box (or in your case, a pair of boxes connected by a fiber optics link) that does bit-by-bit signal propogation between two ethernet segments. Xerox sells one for local use (that is, the two wires are close enough to each other to use normal transceiver cables to get from the repeater to each of the segments) but I don't know if they have a remote repeater (yet). DEC has announced both flavors of repeaters, but apparently is not yet delivering yet. A repeater makes it looks like you have one long cable, not two subnets connected by gateways. Broadcasts, collisions, everything propogates between the two. There is some limit on the distance for a remote repeater; you'll have to consult the Ethernet spec for details (mine isn't handy).
