Attenuation in fiber means 'loss of optical power' suffered by the optical signal in fiber itself.
Yes, but the fiber attenuates light signal much less than wire attenuates electrical signal in the same length.

A core in fiber optics is a single strand of fiber. It forms one half-duplex channel, where one transmitter can send data to one receiver. In order to form a full-duplex channel, two cores or strands are required. Many fiber optic cables contain many cores organized in many bundles.
It wasn't a one man effort, inventing fiber optics. Works were inspired by John Tyndall who first discovered light can travel an irregular path through glass. Alexander Graham Bell later contributed. Heinrich Lamm in 1930 put the first fiber optic cable together stranding cable together and sending a signal across the wire. There were many other people who helped improve it over the year. Al Gore is not the father of Fiber Optic cables, in case you were wondering.
The transmission characteristic of a fiber optic channel is highly non-linear. It makes it a very bad medium for analog signals. Luckily it doesn't interfere with digital transmissions.
Fiber optics is quicker and has higher bandwidth but for long distances requires more infrastructure (but it is on the planet so is more easily repaired).Satellite communications is slower with lower bandwidth and noticeable delays, the long range capability is greater but parts of the infrastructure (the satellites) are very expensive to replace and repair.

No, fiber optics are cables ran from underneath the ground. The weather will not affect it.
