Optical Spectrum of the 23.6-Gb/s OFDM signal measured with APEX Technologies High resolution Optical Spectrum Analyser[/caption]
This paper shows the great utility of the Apex Technologies High Resolution Optical Spectrum Analyser AP2040/AP2050 series in demonstrating a 23.6-Gb/s optical Orthogonal Freqency Division Multiplexing (OFDM) (20-Gb/s after coding) with a colourless transmitter, realised by optical IQ multiplexing. In combination with 8-QAM coding, DACs with only 4-GHz bandwidth are required to generate the 23.6-Gb/s signal.
