最下方是简易的OOK,如果改用正交相移键控(QPSK),则可将OOK符码率的传输速率提高一倍,因为QPSK可编码二位符号。藉由使用极化复用(PDM)技术,传输速率还可再提高一倍。QPSK加PDM可让使用者在相同时钟速率下,获得2×2=4倍的数据传输速率。最后,利用脉冲整形滤波器进一步缩小占用带宽后,用户可以100Gb/s的速率,透过50G...

We present real-time transmission of 50-Gbaud polarization-division-multiplexed (PDM) return-to-zero differential quadrature phase-shift keying (4 bit/symbol) over five fiber spans, 430 km in total. The two PDM channels are demultiplexed using a beam splitter and automatic optical polarization cont...
采用DQPSK调制与PDM技术提高光纤链路的数据传输图1 使用OOK技术时,当传输速率达100Gb/s或更高,会开始出现信道干扰或调制数据恶化,而复数调制技术可以解决这个问题。 由于相干检测技术可提供完整的光场(OpTIcal Field)信息,这些新概念还允许用户在处理信号时,执行色散(CD)和极化模式色散(PMD)补偿。
