Fiber optics was invented for the same reason that human optics were invented, the fiber was having trouble seeing clearly.
"Optical", in this case, simply means that they work with light.
The telescope was invented in 1608 not 2010. See related question.
The Englishman, Leonard Digges (1520-1559), from Bartham in Kent, UK, invented the Theodolite in 1551...The main component of a Theodolite is a small but powerful refracting telescope, so he was almost certainly the very first person in the world to invent the refracting telescope. However, it is known that he also invented the reflecting telescope shortly afterwards. In 1608, Hans Lippershey, a German born Dutch citizen invented a refracting telescope in Middelburg, Netherlands. Galileo's model a year later was a considerable improvement upon Lippersheys design but it came almost 60 years after Digges's invented his telescope. The Gregorian reflecting telescope was invented by Scottish mathematician and astronomer James Gregory and his design was first published in 1663. Isaac Newton invented the Newtonian reflecting telescope in 1668, 117 years after Digges invented his. The design of the Cassegrain telescope was first published on April 25th 1672 and its invention is attributed to Laurent Cassegrain (1629-1693), a Catholic priest from Chartres, France. There were no real major advances in telescope designs until the Schmidt telescope was invented, by German optician Bernhard Schmidt, in 1930. The Maksutov telescope was patented in 1941 by Russian optician Dmitri Maksutov.
Galileo first invented what is recognized as the telescope.
The telescope was invented by Hans Lippershey, a Dutch eyeglass maker, around the early 17th century. Although the exact origin of the telescope is debated, Lippershey is often credited with its invention.

The non-optical telescope, primarily radio telescopes, were invented in the 1930s. One of the first and most notable radio telescopes was built by Karl Guthe Jansky in 1931.
The Hubble Space Telescope has a number of instruments, but the primary one is an optical telescope.
"Optical", in this case, simply means that they work with light.

Reflector.
See things that don't shine in the visible spectrum.
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.

The surface of a radio telescope doesn't have to be as flawless as the surface of an optical telescope because the radio telescope is collecting radio waves, something that will not be affected by faults in the glass. Optical telescopes, on the other hand, are collecting light, where faults in the surface can interfere with the image.

The Gregorian refracting telescope was invented by Scottish mathematician and astronomer James Gregory in the 17th century. He designed this telescope to address some of the optical issues of the existing telescopes at that time.
