Paper Abstract

We propose a method to generate high-speed frequency-shifted keying (FSK) signal by demodulating two phase-shifted keying (PSK) signals with proper wavelength detuning. The generated FSK is easy for detection and has a small crosstalk to optical label signal. In an 85km SMF transmission demonstration, we achieve 1.5dB power penalty in 10Gbit/s FSK payload and 1dB power penalty in 155Mbit/s amplitude-shifted keying (ASK) label. Compared with the phase continuous FSK, this kind of FSK occupies wider bandwidth due to its phase discontinuity but is simpler in its generation.
