Although isn't the head end supposed to be the "Downstream" optic, while
the client gets the "Upstream" optic?
At least this makes it comparable to the way PON networks operate.
Reason not to use BX might be tx power/rx sensitivity. If your links are
particularly long (> 10km), you might need a typical dual fibre working
optic like a ZX/ER for the reach. In which case there are circulators as
