The paper is focused on the upstream transmission, based on an innovative reflective optical network unit (R-ONU). A detailed theoretical analysis is first presented and used to optimize the system parameters, then we show the experimental results, demonstrating a 16 Gbps upstream bit rate per wavelength.

By a careful optimization of electrical spectrum allocation, semiconductor optical amplifier biasing point, and modulation index, we upgrade previous results over similar architectures, significantly increasing the achievable optical distribution network loss. We demonstrate an overall upstream capacity of 32 Gb/s per wavelength over 37 km of installed fiber and 31 dB loss.

This was obtained by optimizing R-SOA parameters at the ONU, (optional) Faraday rotation and DSP at the OLT.

Research paper thumbnail of BIDIRECTIONAL TRANSMISSION OF THE GIGABIT ETHERNETSIGNAL OVER A SINGLE SI-POF

A single fiber has an overall diameter significantly smaller than a UTP Cat.5 cable; this can be a significant advantage in brown-field home networking installations. We successfully tested our system running real time Gigabit Ethernet traffic generated by a router tester.

We demonstrated that duobinary provides the best performances, without any significant increase in implementation complexity. We investigated also the implementation of the duobinary coder, decoder and its proper equalizer over a FPGA, in order to have an experimental confirm of the results achieved by off-line processing.
