Well, I was triggered by the SFF designation because I've been hacking
SFP transceivers in my spare time... with the huge price markups on
transceivers by the big vendors, it's getting more interesting to buy
quality SFPs and alter the ID strings in a way that they are recognized
as "genuine Cisco" of "genuine HP".

Googling for SFF8472 will also get you hits (eg a great PDF at
ftp.seagate.com), but they might not seem relevant at first glance :)

Good to hear and you're welcome :)
