Abstract :
The performance of a colourless WDM PON architecture based on frequency-shift keying (FSK) by direct modulation of a DFB laser diode for the downstream and intensity modulation by means of a reflective semiconductor optical amplifier for the upstream channel is assessed. The operation of the architecture is demonstrated, showing excellent performance for distances up to 25 km
