PCIe, SATA, SAS, Fibre Channel, Infiniband, and data center flavors of Ethernet are all based on very similar serdes technology that uses multi-GHz binary encoding over shielded cabling. http://www.design-reuse.com/articles/10541/multi-gigabit-ser...

1G/2.5G/5G/10G Base-T Ethernet uses fairly different sub-GHz multi-level encoding over unshielded cabling.



Thanks! That's exactly what I was looking for!

I'm surprised that Base-T is unshielded. Cat-5 and more requires shielding over the full cable, however the cable will contain 4 twisted pairs of wire. Are those pairs of wires considered the "unshielded cabling" for the purposes of this application?


Cat-5, Cat-5e, and Cat-6 are all unshielded by default, but there are shielded versions for high EMI environments.


Huh, I didn't know that. Thanks!


They use differential signaling to reduce noise.
