Sales of Ethernet switches remain flat, but the market for 40 gigabit per second switches is increasing:
The total Q3 Ethernet switch market revenue was $6.1 billion, just two per cent higher than for the same quarter in 2014, and the enterprise share slipped from Q2 to Q3 by 7.2 per cent.
North America was the best place to be selling switches in 2015, with IDC saying is rose 8.2 per cent year-on-year. The Asia-Pac rose 3.9 per cent, China by 3.6 per cent, and Western Europe was nearly flat at 0.8 per cent.
[...] A bright spot for vendors is that customers seem to be drinking the 40 Gbps kool-aid. While 10 Gbps port shipments rose by 27.4 per cent, prices are falling, so the segment value dipped by 1.6 per cent. The 40 Gbps segment, on the other hand, rose 41.4 per cent year-on-year to a value of $644 million.

SFP goes at least to 4G
SFP+ is 10G
QSFP is 40G - 4 colors
SFP25/28 (not quite sure the exact name) is 25G/28G
CXP is for 100G (10x10G)
QSFP28 is for 100G (4x25G), and you use 4 of them for 400G...
Not sure if they will call the new ones for 50GigE SFP56...
