Inventor: JIANG ZHIPING
IPC: H04B10/532
Filed: 2021-03-22
Abstract: Optical transmitters, receivers, and methods are described in an optical network. An optical transmitter comprises an encoder configured to receive an input data stream and to encode the input data stream into a signal. The signal is defined as a sequence of regular units, and a rotator is configured to receive each unit of the signal and to output, for each given input unit with an input state of polarization (SOP), a respective given output unit associated with an output SOP. The output SOP of the given output unit is different from a corresponding output SOP of each other output unit that is immediately adjacent to the given output unit. The output SOPs of the units in a transmitted signal may form an alternating pattern (or other repeating pattern), which may help to lower the average BER, in particular, due to forward error correction (FEC).

Abstract: La présente invention concerne un procédé de préparation d'un noyau de poudre magnétique revêtue de sol-gel modifié par broyage à billes. La poudre revêtue de gel d'AlOOH est soumise à un broyage à billes et à un traitement thermique à haute température, de sorte qu'un nano α-Al2O3 plus uniforme et compact peut être obtenu pour revêtir un noyau de poudre magnétique. Selon la présente invention, la poudre revêtue de gel d'AlOOH est soumise au broyage à billes pour obtenir une couche de revêtement nano α-Al2O3, de sorte que la couche de revêtement est mince et plus uniforme et compacte, et présente une excellente capacité d'isolation. La température du traitement thermique pour la poudre après le broyage à billes est seulement comprise entre 600 et 800 °C, ce qui réduit considérablement la consommation d'énergie, ainsi que les exigences imposées au dispositif. La distribution granulométrique et la morphologie de poudre de la poudre revêtue peuvent être commandées en commandant le temps de broyage à billes, le diamètre des billes de broyage, de la vitesse de rotation du broyage à billes et d'autres paramètres de traitement, ce qui permet d'obtenir des noyaux de poudre magnétique présentant des exigences de performance différentes. Selon la présente invention, le dispositif de préparation est simple, facile à utiliser et à faible coût, et est particulièrement approprié pour une production industrielle de masse et une production à grande échelle.
