Can you put any amount of light into a fiber optic?

It is one of the standard fallacies of the industry. The system required to put a sizeable amount of light in a fiber optic is very easy; a lamp, perhaps a lens and something to has the fiber pointing at the light source.  This follows that the bigger and extreme powerful the lamp the greater amount of light this will issue and the more light which will get in the fiber; at least it is the argument that most people think logical.

The difficulty is that optics is a subject far from easy. An optical fiber will admit a measure of light and no more, in spite of of the power of the lamp: when a light source puts ten units of light by a fiber, another light source, double as bright will not put double the light in the fiber.

Here is one thing termed as power density acceptance that marks the limit to how much energy can circulate by a system, no matter how much more energy you try to force into this. A copper wire of a given thickness will be content with five amps, find warm with ten and heat up along with twenty and forty.
