Will we actually be able to see these speeds over existing copper?
- sigzero 3y agoTheoretically, copper cables can offer speeds of up to 10 Gbps. So they would be pushing the limit.
- megous 3y agoHow so? What's the physical limitation based on?
- ddoolin 3y agoI just found this: https://www.silicon-line.com/copper-cable-limitations/ https://www.silicon-line.com/copper-cable-limitations/ Seems like signal loss is requiring bulkier and bulkier cables or shorter and shorter distances for higher bandwidths.
- zokier 3y agoNothing. Ethernet is already pushing >100G over single (twinax) copper pair.
- wolrah 3y agoWhat you can run over a few feet of twinax and what you can run over hundreds or thousands of feet of coax with multiple tiers of splitters like the DOCSIS specs are designed for are two entirely different things.
- kotaKat 3y agoSure, in 10 years when DOCSIS 6 comes out and your local cableco finally gets D4.
