In reading the documentation for Interlan Ethernet gear, I noticed
a section giving examples of typical Ethernet configurations.  The
simple case had just one cable segment with multiple transceivers.
A more complex example showed two separate Ethernet coax segments,
apparently connected by a repeater.  It looked like the repeater
was between the two segments, and connected to them by transceiver-like
connections.  My questions:  does anyone know what type of cable is
used to connect a section of Ethernet coax to a repeater?  Is is
transceiver cable?  If so, the spec says these can only be 50m long.
Or is it Ethernet coax?  If so, then the only use of a repeater would
be to go beyond the 500m limit of cable sections.  Anyone know of
who makes repeaters?

The way I see using a repeater -- if it uses transceiver cable, not
coax -- would be as a cheaper way to connect distant Ethernets within
a large building (or perhaps even in separate buildings), saving on
cost of coax.  Am I barking up the wrong tree?
