    • Chromatic dispersion is determined based on the arrival times of different frames of data in a wavelength division multiplexed (WDM) system having an optical communication link. Namely, a first frame is transmitted on a first optical channel, which is supplied to the optical communication link. A second frame is then transmitted on a second optical channel and the transmission time difference between the two frames is obtained. At a receive end, the difference in arrival times of the two frames is measured to obtain a relative time delay between the first and second frames. The relative time delay is the sum of the transmission time difference and the propagation time difference (the time difference attributable to chromatic dispersion) between the two frames. Thus, by subtracting the transmission time difference from the relative time delay, the propagation time difference can be obtained. The chromatic dispersion in units of picoseconds/nm can be obtained by dividing the propagation time difference by the difference in wavelength between the first and second optical channels.
    • 基于具有光通信链路的波分复用(WDM)系统中的不同数据帧的到达时间来确定色散。 也就是说,在提供给光通信链路的第一光信道上发送第一帧。 然后在第二光信道上发送第二帧,并且获得两帧之间的传输时间差。 在接收端,测量两帧的到达时间差,以获得第一和第二帧之间的相对时间延迟。 相对时间延迟是两帧之间的传输时间差和传播时间差(归因于色散的时间差)之和。 因此,通过从相对时间延迟减去传输时间差,可以获得传播时间差。 通过将传播时间差除以第一和第二光学通道之间的波长差,可以获得以皮秒/ nm为单位的色散。
