Abstract
This paper reports the first coherent WDM-PON (16×2.5 Gb/s QPSK) experimental demonstration with real-time Nyquist OLT transmitters and real-time ONU receivers. Both transmitters/receivers implemented in FPGA use a simple 8-bit DSP architecture. An optimal transmitted power of −7 dBm per channel is achieved for 50 km, 1∶16 split and 2.5 GHz grid.
