For the cost-effective realisation of the next-generation wavelengthdivision-multiplexed passive optical network (WDM PON), the possibility is evaluated of using the 4-ary pulse-amplitude-modulated (PAM) signal for the high-speed (> 10 Gbit/s) operation of the TOcan packaged reflective semiconductor optical amplifier (RSOA) having a 3 dB bandwidth of only about 2.2 GHz. The results show that, owing...
We demonstrate the error-free transmission of 11-Gb/s 4-ary PAM signal obtained by using a directly modulated RSOA over 20 km of SMF for the cost-effective realization of highspeed WDM PONs.
We investigate the effects of Rayleigh backscattering in a long-reach RSOA-based WDM PON. The results show that the Rayleigh-induced penalty depends highly on the gain of the remote EDFA and the lengths of drop fibers.
