We have demonstrated the first field trial of a real-time 100-Gb/s passive optical network with downstream/upstream data rates of 25/10-Gb/s/λ based on 10G-class optical devices supporting 0–40 km differential reach. We employ a single delay-interferometer (DI) to realize chirp management as well as frequency equalization to combat the chromatic dispersion during the fiber transmission and equalize...
We design and demonstrate a cost-effective 2 times 2 polarization-independent ultra-fast optical switch, which is constructed by a phase modulator based Sagnac interferometer and can support multicasting operation. The measured switching time is ~0.6 ns.
