Abstract :
A wavelength-division-multiplexing (WDM) passive optical network (PON) with centralised light source using downstream polarisation-shift-keying (PolSK) coded by a polarisation modulator (PolM) to facilitate upstream intensity re-modulation is proposed and experimentally demonstrated. Error-free operations for both downstream and upstream signals are achieved in a 20 km-reach 10 Gbit/s WDM-PON without dispersion compensation. The maximum launched optical power and polarisation misalignment tolerance of the PolSK signal are also investigated.
