Abstract:The fourth generation of optical fibers is wavelength division multiplexing (DWDM), where several wavelengths propagate in a single optical fiber. This technique strongly supports broadband communication that is currently being developed. An optical amplifier (EDFA) is required for transmitted information to be received at the appropriate distance limits. The problem, where EDFA should be located and how to overcome the chromatic dispersion of signals occurs, especially on remote communications using SMF 28. T… Show more
