Abstract :
A new scheme for adaptive optical power equalization in passive optical networks is proposed based on dynamic gain control of semiconductor optical amplifiers. Because of this new scheme, continuous-mode receiver front-end can be used for upstream burst-mode transmission. Experimental testbed is demonstrated with -31dBm receiver sensitivity and >34dB dynamic range using continuous-mode receiver front-end.
