We report the field demonstration of 100-Gb/s real-time CO-OFDM detection using polarization division multiplexed QPSK modulation per subcarrier. The paper includes the lowest BER ever reported for a CO-OFDM back-back transmission experiment at 5x10-9 and the successful 495.2-km transmission over mixed types of field installed fiber. The field trial is conducted in a dispersion managed WDM system with neighboring 10Gb/s Ethernet channels.

  • Sharma S.

5G networks will have to support a set of very diverse and often extreme requirements. Network slicing offers an effective way to unlock the full potential of 5G networks and meet those requirements on a shared network infrastructure. This paper presents a cloud native approach to network slicing. The cloud ...

Based on the physical model of a bulk reflective semiconductor optical amplifier (RSOA) used as a modulator in radio over fiber (RoF) links, the distributions of carrier density, signal photon density, and amplified spontaneous emission photon density are demonstrated. One of limits in the use of RSOA is the lower ...

How to preserve users' privacy while supporting high-utility analytics for low-latency stream processing? To answer this question: we describe the design, implementation and evaluation of PRIVAPPROX, a data analytics system for privacy-preserving stream processing. PRIVAPPROX provides three properties: (i) Privacy: zero-knowledge privacy (ezk) guarantees for users, a privacy bound tighter ...
