The bare fibre is more reliable than copper, as it doesn't need all
the extra equipment to carry today's digital signals. Fibre can carry
data much further than copper ever dreamed of. Years ago, a company
might get a DS1 (T1) line, which ran at a blazing 1.544 Mb/s! It also
required repeaters about every 6000', IIRC. The coax based cable
network likewise has distance limits that require amplification.
Depending on the bandwidth and fibre, distances with it can be
thousands of Km.
Bare fibre is more delicate than copper.
We spend a day and a half down because someone put too sharp a bend in a
fibre cable.
