Introduction

Pierluigi Poggiolini is a notable inventor based in Turin, Italy. He has made significant contributions to the field of optical transmission technology, holding a total of 5 patents. His work focuses on enhancing the efficiency and capacity of optical data transmission systems.

Latest Patents

One of Poggiolini's latest patents is titled "Optimization of Optical Transmission Capacity." This invention describes a method for transmitting a coherent optical data signal. It involves receiving a data signal from an interface and encoding it with a forward error correcting (FEC) encoder that utilizes a mix of modulation formats. The FEC encoder generates an FEC encoded signal, which is then used to create modulation symbols. These symbols are spectrally shaped to produce a shaped signal, which is pre-distorted before transmission. The pre-distortion process includes adding a predetermined amount of chromatic dispersion to generate a smoothed signal for effective transmission.

Another significant patent is "Adaptive Equalization in Coherent Receivers Using a Stokes Space Update Algorithm." This invention features a coherent optical receiver that includes an optical transducer, an adaptive filter, and a processor. The adaptive filter is updated based on a metric derived in Stokes space. The optical transducer receives an optical signal corresponding to a modulated signal of symbols and determines signals corresponding to different polarizations. The adaptive filter recovers equalized signals from these inputs, forming an equalized modulated signal of symbols.
