Optical transmission apparatus using duobinary modulation |
摘要 |
<p>An optical transmission apparatus using duo-binary modulation adapted to an optical communication system using dense wavelength division multiplexing (DWDM) is disclosed. The duo-binary optical transmission apparatus includes an electro-absorption modulated laser (EML) for performing a light intensity modulation operation based on an electrical data signal and producing a modulated optical signal, the EML having a light source for outputting carriers and a modulator for performing the light intensity modulation operation, a precoder for inputting an inverted signal of the electrical data signal and encoding it to an encoded signal, and a modulator for performing a phase modulation of the optical signal modulated by the EML and outputting a duo-binary optical signal, according to the encoded signal.</p> |
