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.
More info about 25 Gigabit Ethernet (and 50), and 100 Gigabit Ethernet (and 40).

What cables to buy? What connectors? What switches? No? Well, that must be why people still deploy copper lines.

SFP+ ?

Great example of the general confusion seeing as SPF+ is 16Gbps while the article discusses 40Gbps.
* 10Gbps in practice but I'm not getting into that...

SFP+ I have seen is 5gbps; sometimes 10gbps, but if so it's usually proprietary to replace genuine stacking cables between switches in a stack or virtual chassis.
And I do not endorse its use; it seems pretty shoddy to me. Perhaps its just been the cables and vendors I've seen pushed regarding its use; it could be there are quality components out there and I have been on cheap projects.
if SFP+ means 16mbps token ring, I wouldn't be surprised because it seems to mean everything faster than 1gbps.

No no you were right the first time. It's a mess of property lock-ins, sub(non-existing)standard performance and price gauging.
It won't be safe to use until you'd be able to go into Walmart, ask for a fiber extension wire or a fiber LAN switch, and get what you want without having to say another word. That is, if you need to google anything to do with connectors or fiber materials, types and widths, you might be doing it right, but the market is doing it wrong so you better stir clear.

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...

In-house as in residential fiber? Why? Monitor your network usage. How often do you even go above 100mb let alone 1000mb? 1g copper will readily support a full household of 4k streaming internet addicts at a fraction of the price.

yaha. what if the pci-e ssds are 10 or 50 or 1000 meters apart?
pcie ssd are 256 gb and "cheap". if the cpu supports 6 or 7 or 8 GT/s (gigatransfers) then the pcie ssd is not going to waste and then 1 gigabit ethernet is your bottleneck.
so yes i would like more in-house bandwidth?

If your house is 1000 meters across and have a need to bulk transfer at ssd speeds at that distance it'd be faster to just get into your gold plated Bentley and drive your storage to the other side of the compound.
