摘要:
In a WDM optical network DML signals are sideband filtered to compensate for chirp with a feedback loop carrying signals from a monitor unit which helps maintain the sideband filter offset from a peak output of the DMLs. Network components with filtering characteristics, such as AWGs, can be used as the sideband filters. The monitor units monitor the Q-factors or BERs of the filtered signals and the sideband offset is maintained by temperature control of the sideband filters with respect to the DMLs.
