摘要
Provided is an optical transmission apparatus and method for uplink transmission in an orthogonal frequency division multiple access-passive optical network (OFDMA-PON), wherein the optical transmission apparatus includes a digital signal processor to output a baseband orthogonal frequency division multiplexing (OFDM) signal, a tone generator to generate a dithering tone, a synthesizer to synthesize the dithering tone and the baseband OFDM signal, and an optical source to output an output light in which a spectrum width is increased to be greater than a spectrum width of a carrier light based on the baseband OFMD signal synthesized with the dithering tone.
