Web Pro Forum There is a lot of stuff here, some of which is linked to on this page.
The Glass Menagerie This is Cornings Web Site. I have link as well as well as on the vendor page because there is a lot of good stuff here on fiber and how to characterize it. They make you register so I can't link to it directly.
