I want to know why they don't use Aluminum in piping for plumbing, it's supposed to be cheaper.?
Who cares? The only thing that I think is important is the bottom line speedThe details of each step in getting there are only important to engineers who are designing a systemThere is some translation no matter what the technologyFiber is so much faster than cable that there is no comparisonThat is what is important, not the steps it takes to get thereAdditional: Rootbrain2000 does not know that some places have fiber all the way, not just to the neighborhood, i.eFTNAlso, the physical composition of the wiring is not the questionThe question is speed, not construction.
A little amountIt really depends on the route your data takes in the provider's network that would determine it's latency between one technology and another.
Cable is aluminum shielded copper, fiber only goes from the ISP's hubs to their server rooms, copper wire from the one coming to your home, so it's not 100% fiber optic.
Edit Aluminum is not used for domestic plumbing primarily because it is much more expensive than threaded, galvanized steel and not as strongSch 40 CPVC threaded or solvent joint pressure piping is now especially preferrered for cold water and domestic hot water Along with galvanized pipe, copper tubing had been long preferred until costs and concerns with lead-based solders made copper unattractiveAluminum has not been popular except for a time a few decades ago when low cost put in into electrical wiring and possible into some limited small domestic pipingIt was and is used in thin wall , larger diameter low pressure industrial -type piping.
