We report for the first time a 1 Tb/s transmission over a single core fiber, by using 10 spatial modes, namely the two polarization modes of 5 distinct spatial modes. Each one carries 100 Gb/s per mode per polarization, modulated with a 56 GBd quaternary phase-shift keying modulator. This optical channel occupies a 66 GHz-wide slot in a wavelength division multiplexed comb made of 3 channels. This results in a record spectral efficiency of 15.2 b/s/Hz. A bit-error rate below the error correcting limit after 20 km has been measured.

A Cloud Native Approach to 5G Network Slicing

  • Francini A.
  • Miller R.
  • 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 ...
