Over the next year I'm looking to buy 20 to 80 gigabit ethernet converters,
going from 850 nm to 1310 nm. What is the cheapest way to do this
reliably?
I priced out a new switch and price is too high especially for the 1310 nm
SFPs. Can someone suggest a way to do this on the cheap? I'm perfectly
willing to consider high quality used or surplus equipment, and older
discontinued products.

Can you put $ values on the statement you just made?

Switches with SFP modules were going about $400 to $700 and the 1310 nm SFPs
were running $300 to $500. Looks like about $700 to $1K for the package.
I'm budgeted about $300 per converter.

But with $300 1310 nm SFP's, it doesn't seem like there would be much
room left in your $300 budget for the rest of the converter (a PCB,
power supply, 850 nm optic, case, misc parts and components).
I've done much more complex designs than this before. Are there any
special requirements (like that the box must be completely sealed, or
operate over a specific temperature range)? What power source(s) are
available (guessing AC 120V, but it doesn't hurt to ask).

How big are your groupings? Or is it half in a central distribution
location and the other half as individual units at destinations?
Just thinking that if you had groupings of them, then -possibly-
something like a switch with two line cards, hardwired with each
type, with bridging configured between each respective port pair.
