SYSTEM UND VERFAHREN ZUR SPEKTRALEFFIZIENTEN ÜBERTRANGUNG VON DIGITALEN DATEN ÜBER EINE OPTISCHE FASER |
摘要 |
A system transmits digital data over an optical fiber at high aggregate data rates and high bandwidth efficiencies. The system includes a modulation stage, a frequency division multiplexer, and an optical modulator. The modulation stage QAM-modulates a plurality of incoming digital data channels. The frequency division multiplexer combines the QAM-modulated signals by frequency division multiplexing them into an RF signal. The optical modulator uses the RF signal to modulate an optical carrier for transmission over an optical fiber. |
