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.
