We present a final demonstration of upstream FDMA-PON transmission on the EU project FABULOUS architecture. We show WDM capability over four wavelengths, each carrying 32 Gbps at 31 dB ODN loss, and DSP real time implementation on a commercial FPGA.
We demonstrate 32 Gbps per wavelength upstream record capacity for a FDMA-PON over 37 km of installed fiber and 32 dB ODN loss, adopting an innovative ONU based on a reflective Mach Zehnder modulator.
We present a self-coherent reflective PON demonstrator, TWDM-PON compatible, running at 10 Gbps upstream bit rate per ONU using commercial DFB lasers, achieving 31 dB ODN loss at BER=10−3 over splitter-based PON in TWDM-like burst mode operation.
We experimentally demonstrate a FDMA-PON system targeting 20 Gbps per wavelength in the upstream, using a real-time FPGA-based transmitter and low-speed baseband DSP, and 39 Gbps in the downstream using a new resources allocation algorithm with 11.5GHz electrical bandwidth, in the framework of the EU research project FABULOUS.
Optical phase modulator based on OIL-VCSEL is investigated for the first time. Simulation shows a directly modulated OIL-VCSEL can function as a key component in QPSK or 8PSK transmitters. Preliminary phase-shift-keying characteristic is demonstrated experimentally.
The upstream performance of a slave VCSEL transmitter injection-locked by modulated downstream signals from a master DFB laser in a WDM-PON is investigated as a function of downstream extinction ratio, showing minimal dependency and variation in performance degradation.
