Abstract
In this paper, a centralized-light source-passive optical network (CLS-PON) structure with downstream 10Gbit/s frequency shift keying (FSK) signal generated by polarization modulation and upstream 10Gbit/s inverse-return-to- zero (IRZ) signal has been demonstrated by simulation. The bit error rate (BER) of downstream and upstream signals has been investigated in the case of back-to-back and the transmission of 20-kmsingle-mode fiber (SMF) with no dispersion compensation, showing a potential transmission performance. Besides, the influence of FSK frequency spacing of 20GHz and 30GHz on the downstream and upstream signal has also been discussed. Moreover, the good dispersion tolerance of IRZ upstream is compared with ASK upstream.
