Essentially, yes. SFPs are more common now, I presume largely due to
their smaller physical footprint ("Small Form Factor Pluggable GBIC").
They perform exactly the same function as GBICs, but I think you'll
find there is a larger range of SFPs available. On the fibre optic
front, you'll find the same options like 1000BASE-SX (MMOF),
1000BASE-LX/LH and 1000BASE-ZX (SMOF) etc.
GBIC and SFP slots are available for many platforms -- not just 6500/7600.
When you get into the world of 10 gigabit Ethernet, you'll discover
there are even more form factors: XENPAK, X2, XFP -- maybe even other
that I'm not aware of.
cheers,
Dale
