Just the connectors. In an emergency, one can shove a round peg into
a square hole. (ST will friction-fit into most SC fittings and work.)
No significant performance difference.
In terms of the physical medium, duplex is two fibers with a figure-8
jacket. Looks a lot like lamp cord. Convenient because the transmit and
receive fibers are physically tied together into a common jacket. Simplex
is a single fiber.
Riser/Plenum has the outer protective jacket made of a material that does
not produce toxic fumes (or produces less such fumes) when it burns. The
glass fiber itself doesn't burn, but the outer jacket is plastic.
