The Cloud Area Padovana is an OpenStack-based scientific cloud, spread across two different sites - the INFN Padova Unit and the INFN Legnaro National Labs - located 10 km away but connected with a dedicated 10 Gbps optical link. In the last two year

A multi-wavelength tuneable OTDR is realized and tested for in-service monitoring of a colourless WDM PON. The instrument regenerates the probe optical pulse by modulating, through an acousto-optic modulator, the continuous wave emission of a tuneabl

We experimentally generate localized and stationary dynamic Brillouin gratings in a 5 m long polarization maintaining fiber by phase-modulation of the pumps with a pseudo-random bit sequence. The dynamic Brillouin gratings are characterized in terms

We experimentally demonstrate reconfigurable ultra-narrowband optical filters realized by localized dynamic Brillouin gratings in a polarization maintaining fiber. The filters are characterized in terms of bandwidth, optical signal-to-noise ratio and

Here, we present a WDM PON monitoring technique that uses a single wavelength OTDR and a standard telecommunication laser, tuneable over the ITU WDM grid. The coherent Rayleigh noise (CRN) is actually reduced by avoiding to regenerate the pulse by di

Polarization attraction in counterpropagating, randomly birefringent, fiber Raman amplifiers is numerically investigated, including the effects of nonlinear polarization rotation, pump depletion and orthogonal Raman gain. The analysis determines the

We report an experimental demonstration and characterization of dynamic Brillouin gratings (DBGs) in a 5m long polarization-maintaining fiber (PMF) using heterodyne detection. The dependence of DBG reflectivity on the Brillouin gain and on the pumps

We analyze the performance of a degenerate vector PSA-based receiver and compare to an EDFA-based receiver, achieving an about 1 dB sensitivity improvement. We also assess the phase regeneration provided by the vector PSA when the signal phase is deg

We comprehensively investigate a degenerate vector phase-sensitive amplifier (PSA). We determine the gain dependence on the relative phase and polarization angle between the pumps and the degenerate signal wave. The vector PSA is experimentally shown
