Dwdm modulation
Dense wavelength division multiplexing (DWDM) refers originally to optical signals multiplexed within the 1550 nm band so as to leverage the capabilities (and cost) of erbium doped fiber amplifiers (EDFAs), which are effective for wavelengths between approximately 1525–1565 nm (C band), or 1570–1610 nm (L band). EDFAs were originally developed to replace SONET/SDH optical … WebJun 27, 2014 · Większość wyzwań technicznych związanych z 40G DWDM jest już powszechnie rozumiana, ponieważ wyzwania ze świata 10G osiągnęły bardziej wymagający poziom. ...
