  • Preface
    be accomplished at different levels. When in electronic form, many signals may be multiplexed in the time domain using time compression (or bit rate upping), such as time division multiplexing (TDM), by bit interleaving as in VTs of SONET/SDH, or by packet interleaving. In DWDM, multiplexing means many

    ) but also allowed signal regeneration after 80 km or more. The pace of innovation in all fields of lightwave technology only quickened during the 1990s, as evident from the development and commercialization of erbium-doped fiber amplifiers, fiber Bragg gratings, and wavelength-division-multiplexed
