    • A WDM system having at least two channels, each of which employs two polarizations, is arranged so that the start times of symbols carried by one polarization of a channel are displaced in time from the start times of symbols carried by the other polarization of that channel, e.g., the start time for each symbol on one polarization is not substantially synchronized with the closest-in-time symbol start time on the other polarization of that channel. Preferably, the data signals are modulated using a return-to-zero (RZ) format and the start times of the symbols of the data signal carried by one polarization of a channel is offset from the start time of the symbols data signal carried by the other polarization of that channel by between 20% to 80%—preferably 50%—of the symbol period of the data signals, when the data signals have the same symbol period.
    • 布置具有至少两个通道的WDM系统,每个通道采用两个极化,以使得通道的一个极化所承载的符号的开始时间从该通道的另一个极化所承载的符号的开始时间的时间偏移 例如,一个极化上的每个符号的开始时间基本上与该通道的另一个极化上的最接近时间符号开始时间同步。 优选地,使用归零(RZ)格式对数据信号进行调制,并且通过信道的一个极化承载的数据信号的符号的开始时间偏离由信道携带的符号数据信号的开始时间 当数据信号具有相同的符号周期时,该信道的其它极化在数据信号的符号周期的20%至80%之间优选地为50%。
