Abstract :
We demonstrate a 1.25 Gb/s long reach PON (66 km+1:128 split) based on a simplified phase-diversity homodyne coherent receiver, which uses a common DFB as local oscillator, has simple processing and needs no frequency locking. -48 dBm sensitivity allows for a 47 dB power budget. Good channel selectivity (6.25 GHz) is achieved.
