Thin coax Segment
v
Sometimes several Ethernet Hubs must be co-
located to support a larger array of stations than
can be handled by a single Ethernet Hub. Then it
is useful to stack the Ethernet Hubs by joining
their BNC connectors with 0.5 meter patches of
thin coaxial cable. Such stacking is just a special
case of thin coaxial cable connection as treated
above, and the terminator rule is the same: If the
stack is at the end of the incoming cable, then a
50-ohm terminator must be substituted for the
continuation cable shown in the stacking diagram
below.
