Make fibre advantage "Electrical isolation" a separate point, so it's more prominent than a side-comment of "Less interference".

Oct 23, 2019 at 15:22 | comment | added | Peter Green | There are virtually no pure-analog phone systems left. Your line may be delievered to you as an analog copper pair but as soon as it hits the telephone exchange it almost certainly gets digitised. Consumers think analog is better becaue they are comparing their "analog" (in practice digitised at the telephon exchange) line from a high-quality telco to a VOIP service that runs over the open internet (sharing a "best effort" communications medium with bulk data transfers) or a cellular service (subject to the vaugarities of mobile radio communictions) | |
Feb 24, 2018 at 12:16 | comment | added | InterLinked | @immibis Don't need a source, though there are plenty out there. It's just common sense. Analog telephones provide superior call quality to digital every time, especially if the digital phone is VoIP which is often the case these days. | |
Aug 11, 2016 at 14:36 | comment | added | InterLinked | Perhaps the most important advantage of copper over fiber: copper can carry power to supply telephones whereas fiber cannot. This is why copper is ideal for the local loop since telephones that draw power from the line can remain operational on a copper line. Copper also carries analog signals which are superior in terms of quality to digital | |
Jan 10, 2016 at 11:07 | comment | added | uhoh | I like this answer too. I'm not sure about the expense - I think the answer applies more to "local" than it would to "long distance". Laying enough copper at the bottom of the ocean to reliably carry even 1 Tb/sec from one continent to the other might not be so cheap. In fact I'm not even sure what that would look like! | |
Feb 2, 2015 at 20:44 | comment | added | user4565 | @Jordan, that is true. We have further reduced the cable density by using bi-di SFPs which uses a single single mode fiber strand for 10G vertical links. Yamasaki made them somewhat affordable... | |

Feb 1, 2015 at 16:19 | comment | added | Jordan Head | Great answer, I'd like to add one thing if I may. In large scale environments that require tons of fiber, it's physical profile is much smaller, and it can handle much higher cabling density as a result. | |
