Intra-transceiver optical superchannel switching via RF sub-band multiplexing technique

摘要

Systems and methods are disclosed for data communication by performing RF sub-band multiplexing and demultiplexing by cascading a radio-frequency (RF) mixing module and optical dual-polarized (DP) QPSK modulator forhybrid RF/optical IQ modulation; and performing intra-transceiver optical superchannel switching through the RF sub-band multiplexing.
