[ARS] Intel’s 800Gbps cables headed to cloud data centers and supercomputers

ntel and several of its partners said they will make 800Gbps cables available in the second half of this year, bringing big speed increases to supercomputers and data centers.

The new cables are based on Intel's Silicon Photonics technology that pushes 25Gbps across each fiber. Last year, Intel demonstrated speeds of 100Gbps in each direction, using eight fibers. A new connector that goes by the name "MXC" holds up to 64 fibers (32 for transmitting and 32 for receiving), enabling a jump to 800Gbps in one direction and 800Gbps in the other, or an aggregate of "1.6Tbps" as Intel prefers to call it. (In case you're wondering, MXC is not an acronym for anything.)


This going to be expensive!

I can imagine the cabling costing a few hundred dollars per foot... 64 optic cables....

So just throwing some numbers together......

PCI-e 3.0 x16 = 8GT/s = 32GB/s = 256 gbps

How are you gonna use that 800gbps at home again?

DDR4 is slated to come in at about 20gbps!!

For people who don't work in industry that see a bit of news like this its impressive.

To people like me and you, its not at all.

25Gb/s per pair.... but 32 pairs in a single cable....

How many modes can phase into current multi-mode cables?
