SFP interchangeability

Well, the ADVA 850mm SFP's that apparently weren't compatible with the Cisco 3560,

DO WORK in a Juniper EX2200. This is a HUGE savings, as I picked up 6 ADVA SFP's for $35.00, and the cheapest Juniper compatible SFP's I could find were $45.00 a piece.

Obviously, ADVA branded, but actually, a Finisar product...
