Fiber will cary any speed imaginable its not limited, and CAT5 carries only 100 mbit. The expense is about 1000 times CAT5 for fiber. It's VERY expensive to lay fiber. We are talking low 6 figures per about 100 feet of cable. Typical cost of multimode fiber per foot is around $0.75 compared to $0.10 for Cat5e Gigabit certified copper cable.

Feedback received on this FAQ entry:
  • I don't know if this is old information, or if it's based on having work done by a commercial contractor or what, but it seems extremely out of date considering you can buy a 100 meter roll of dual multimode fiber with preattached LC connectors for under $100 on eBay, and we just picked up two brand new media converters with the LC modules for $115 apiece. Considering that copper is going up in price and simply doesn't work well on runs that even approach the theoretical 100 meter maximum (particularly buried underground runs, and more particularly after there has been a nearby lightning strike), I would say that it may be cheaper in the long run to just run fiber than Cat 5e underground, unless one lives in a place where lightning never strikes. In any case, unless I'm missing something here, the "low six figures for 100 feet" is ludicrous beyond belief! Perhaps there is a need for a separate FAQ for home/SOHO fiber. Just as 10Base-T and 100BaseT wired networks are considerably different from DSL (even though both use copper wires), using fiber to connect a couple of nearby buildings is far different from a 50 mile commercial fiber circuit. And believe me, there is not nearly enough information out there for do-it-yourselfers that are trying to do their first fiber run - I'd love to find even ONE good page on the subject.
