Hi Dan
Does 100baseFX_Half make an sense? My understanding of 802.3 section
26 is that it is always a pair, not a single fibre where you might
need CSMA/CD?
I actually questioned that too and looked it up
I found these and thought they could be viable
http://www.certiology.com/tech-terms/network/100base-fx.html
"The 100Base-FX can be used in a maximum length of 412 meters if being
used in
half-duplex connections or as 2 kilometer lengths in the case of
full-duplex transmissions over optical fiber."

Of course I never have seen one myself
