Abstract :
In this work we propose a novel wavelength division multiplexing passive optical network (WDM-PON) configuration. The system is based on a colorless optical source employing the injection of amplified spontaneous emission (ASE) into a reflective SOA (R-SOA). In addition, optical detection at the ONTs is carried out by PIN based receivers, without decision threshold level adjustment (DTLA). We investigated the system performance for four directly modulated 1.25 Gb/s channels at the C-band in the presence of chromatic dispersion and experimentally demonstrated error free operation for downstream traffic in a 20 km reach, with 1.0 dB penalty.
