Dual-polarization optical bursts for reception by a coherent burst mode receiver with fast adaption

摘要

The invention relates to a modulation method for generating optical bursts. Such an optical burst comprises a first header section (1) and a payload section (4). The first header section (1) is a single-polarization signal and is in a first polarization. Preferably, the symbol rate of the first header section (1) is lower than the symbol rate of the payload section (4). The payload section (4) is a dual-polarization signal having a signal in the first polarization and a signal in a second polarization. Preferably, the two signals of the payload section (4) are PSK modulated signals, such as BPSK, QPSK, DQPSK or DBPSK modulated signals.
