Spectrum-Sliced WDM Using FSK Transmission
ثبت نشده
چکیده
The focus of this chapter is to consider the case of spectral-slicing when Frequency-Shift Keying (FSK) is used as the modulation scheme. Although the majority of lightwave systems use conventional On-Off Keying (OOK) or intensity modulation, FSK is preferred in certain situations and this chapter will discuss where transmission using FSK may prove advantageous in the context of a noise-like spectrum-sliced system. The mathematical formulation of this problem is followed by an analysis of the receiver sensitivity and comparison with the results for OOK discussed in the previous chapter.

Reflective semiconductor optical amplifier fiber cavity lasers (RSOA-FCLs) are appealing, colorless, self-seeded, self-tuning and cost-efficient upstream transmitters. They are of interest for wavelength division multiplexed passive optical networks (WDM-PONs) based links. In this paper, we compare RSOA-FCLs with alternative colorless sources, namely the amplified spontaneous emission (ASE) spe...

Spectrum slicing is a novel technique for the implementation of wavelengthdivision multiplexing (WDM). While conventional WDM systems employ laser diodes operating at discrete wavelengths as carriers for the different data channels that are to be multiplexed, spectrum-sliced systems make use of spectral slices of a broadband noise source for the different data channels, thus being economically ...
