Re: Low cost WDM gear

Oh, I had no fantasies that the $500 Chinese muxes would do the distance. Actually quite the opposite in that I knew 
they couldn't, so looking for alternative solutions that didn't break the bank.

Agree - US$500 (or thereabout) to cover 300km at a reasonable speed with 
some reliability and manageability is a stretch (no pun intended).
