, What is Fiber Optics

Fiber optics, or optical fiber, refers to the
technology that transmits information as light pulses
along a glass or plastic fiber.

A fiber optic cable can contain a varying number of
these glass fibers from a few up to a couple hundred.
Another glass layer, called cladding, surrounds the
glass fiber core.

, Population inversion and optical pumping
Increasing the population of atoms or electrons in
the higher energy state using light such that the
population should be more than the population in
the lower energy state is called population inversion
and this process is optical pumping.
