The main target of advancement with the fifth era of fiber-optic communications is on extending the wavelength assortment around which a WDM method can run. The standard wavelength window, called the C band, handles the wavelength range 1525–1565 nm, and dry fiber provides a low-reduction window promising an extension of that array to 1300–1650 nm.
Fiber optics is also the basis with the fiberscopes Employed in examining inner portions of the body (endoscopy) or inspecting the interiors of produced structural solutions.
