WebIn optics, optical power (also referred to as dioptric power, refractive power, focusing power, or convergence power) is the degree to which a lens, mirror, or other optical system converges or diverges light. It is equal to the reciprocal of the focal length of the device: P = 1/f. [1] High optical power corresponds to short focal length. dictionary forthWebThe three main wavelengths used for fiber optic transmission are 850, 1300, and 1550 nanometers.
