Summary: This paper proposes a novel cost-effective construction scheme for centralized lightwave wavelength-division-multiplexing passive-optical-network (WDM-PON). In optical line terminal (OLT), it employs a single super-continuum light source for the whole system that the downstream data can be modulated in each wavelength channel; and at optical network unit (ONU), it uses part of the downstream as carrier to re-modulate upstream data. The scheme reduces the optical sources used in OLT and simplifies the structure of ONU, so that the construction costs can be greatly solved. Considering that the changing of modulation formats for both downstream and upstream data can have great effects on system performance, this paper also deeply analyzes those WDM-PON construction schemes of various downstream and upstream modulation formats. By simulation, the relationship between receiving power and bit error rate (BER) of 10Gb/s downstream and 10Gb/s upstream back-to-back and 20km system of all schemes are analyzed.
