Shortwave radiation (SW) is radiant energy with wavelengths in the visible (VIS), near-ultraviolet (UV), and near-infrared (NIR) spectra. There is no standard cut-off for the near-infrared range; therefore, the shortwave radiation range is also variously defined. It may be broadly defined to include all radiation with a wavelength of 0.1μm and 5.0μm or narrowly defined so as to include only radiation between 0.2μm and 3.0μm.

WebDue to the nonlinear effect of SRS, they exchange energy while propagating through the fiber. Energy from channels on the short wavelength side is transferred to channels on the long wavelength side. This energy transfer results in a tilt of the channel power distribution at the output of the fiber. FIGURE 6.7. WebIn radio, longwave, long wave or long-wave, and commonly abbreviated LW, refers to parts of the radio spectrum with wavelengths longer than what was originally called the medium-wave broadcasting band.
