An apparatus comprising a frequency-domain equalizer that has been iteratively generated to compensate for filtering effects of a wavelength selective switch, wherein the FDEQ is configured to process in a frequency domain digital samples of a polarization multiplexed phase-shift-keying signal that has been transported over an optical channel.

Method and apparatus of using digital equalizer for cascaded wavelength selective switch compensation

A data transmission method is disclosed, and the method comprises: encoding binary data to be transmitted with encoding principle as follows: encoding binary data x1 in the manner of no jumping at middle phase; encoding binary data x2 in the manner of jumping at middle phase; and after encoding two binary data x1 consecutively with high level of no jumping at middle phase, encoding the immediate following binary data x1 with low level of no jumping at middle phase; encoding binary data x1 with high level of no jumping at middle phase, wherein the binary data x1 follows binary data x1 encoded by using low level of no jumping at middle phase; and encoding binary data x1 immediately following binary data x2 by using high level of no jumping at middle phase; modulating the encoded data; and transmitting the modulated signal.
