Abstract
A centralized seeding source based loopback WDM-PON is fundamentally limited by Rayleigh backscattering (RB) noise. Here a novel modulation format, called as Coded RZ (CoRZ), is proposed to enhance the system performance in the presence of RB for RSOA based reflective access networks. The result shows that the proposed technique can be effectively improved the tolerance of signal-to-crosstalk ratio (SCR) by about 8 dB and 2.5 dB from conventional NRZ and RZ modulation formats respectively to maintain power penalty ≤ 2 dB.
