Wrong, so wrong. Fiber has so many advantages over copper it's not even funny.
Fiber is NOT expensive to maintain. Once it is in place and installed properly, it's DONE. Water doesn't affect it. Lightning doesn't affect it, unless it's a direct hit. Fiber has virtually unlimited capacity, and isn't affected by the weather. It has also become cheaper and BETTER in terms of quality over the past decade.
Fiber has advantages and disadvantages.
Fiber is NOT powered by the telco, a battery is needed in each house or users location. If the battery is damaged or simply fails the fiber connection is lost.
UTP is powered by the telco and is very reliable UNLESS you have a wireless phone(s) and don't have a hard wired phone, users choice.
If an untrained user looks into a fiber cable their retina can be damaged, the light is invisible BTW.
If an untrained user looks into OR touches a UTP there is NO injury.
When a fiber cable is damaged, typically by construction, the time to repair the cable is extended period because of the complexities of the repair.
UTP repair is as easy as screwing on a wirenut.
Lightning does effect fiber and can/has destroyed it.
Fiber cable has been damaged by gunshots, underwater landslides, tree falls, water main failures in addition to construction activities like copper/coax.
Fiber can be faster but if you look at speeds offerred by Monticello using their fiber network they are the same speeds as offerred by telcos over UTP.
If you consider the reaction to the fiber offerring by Monticello the users have NOT jumped onboard the fiber train. I.E. even residents who have a vested interest in their cities fiber system have NOT signed up for the fiber service.
In fact the competition simply lowered their rates and users are clammering to save the money. Meanwhile the city of Monticello is claiming the competition is using peredetary pricing or some such nonsense to keep long term users of theirs.
As if the competition should NOT do anything that might make the cities fiber offerring to expensive. The ignorant city didn't even consider how the competition would lower prices, instead counted on stable prices. Bunch of idiots.
