You'd do it using an SFP cage, so the actual optics could be swapped in
for standard commercial ones, and generic 1G LR optics should be < US$10
in small quantity by now (they've been much less than that in tray
quantity for at least a decade), and drive 2km easily.

I've done a little design with SFP for a previous (work-ish) project,
and basing it on the redesigned Spectracom 8140 pods I did a few years
ago[1], I could probably knock out a prototype design in an afternoon.

(Quite if I ever will, and when is a different matter)
