摘要： The present invention relates to an IM-DD optical transceiver working with a double-sideband (DSB) and single-sideband (SSB) hybrid signaling. A multicarrier signal using a subcarrier interleaved configuration is transmitted from at least one transmitter towards at least one receiver through at least one optical fiber link. A respective first quality performance of each subcarrier transmitted in a DSB modulation format is compared to a respective second quality performance of each subcarrier transmitted in a SSB modulation format. The modulation format amongst DSB and SSB is respectively selected for each subcarrier as to achieve the better quality performance. A selective filling of each subcarrier can then be obtained in order to get a multicarrier signal free of CD-induced fading dips even after its transmission through the fiber link and an optical-to-electrical conversion at the receiver side.

摘要： An optical communication system that comprises a transmitter adapted to generate a signal by modulating a transmission data as low power consumption symbols of an amplitude modulation format and a monitoring data (MD) as high power consumption symbols of the amplitude modulation format, the MD comprising at least one transmitter parameter and/or at 5 least one receiver parameter of communicating the transmission data. A binary logarithm of a total number of the low power consumption symbols and the high power consumption symbols is a non-integer.
