The maximum performance of Ethernet cables is determined by factors like speed standards, cable type, and distance.

I just watched a video about Ethernet cables and they covered category 7 and 8, up to 10bgps and 40Gbps. I’m curious about how far we can push Ethernet speeds. Can we hit 100Gbps? Is it possible to reach 400Gbps by combining several lines into one cable? Could we use a different material for wiring to boost performance? And could we design a new type of cable with more internal wiring, similar to USB 3.1 Gen2?
We already possess optical fibers, though their use in everyday homes is still limited.
Currently available options include 25gbps and 50gbps Ethernet cards for roughly $180 to $250. A 50gbps model is available, along with a QSFP28 cable estimated at about $50 for a 3-5 meter length. Copper connections can reach up to 40 gbps, while shorter distances allow higher speeds such as around 42gbps with HDMI 2.2. The latest fiber technology offers up to 400 gbps, with future plans aiming for 1600 gbps. Using multiple fiber pairs can help achieve these speeds, though copper performance diminishes with longer runs due to increased power needs and error correction requirements.
