1. a kind of optical device, including:

  • For providing the device of optical signalling;

    AndManipulator, including:

    For modulating the X polarisation channel (X channel) of described optical signalling using training modeWith the device of Y polarisation channel (Y-channel),Described X channel includes in-phase channel (XI channel) and orthogonal channel (XQChannel),Described Y-channel includes in-phase channel (YI channel) and orthogonal channel (YQChannel);

    For the device so that described X channel is interfered with described Y-channel;

    AndDetermine described optical signalling for after interfering with described Y-channel in described X channelMeasuring light power device;

    AndController, including:

    For generate control signal with based on described optical power measurement be aligned with describedThe device of the deflection of optical signalling association;

    AndFor providing institute to the tributary manipulator in two or more tributary manipulatorState control signal to change the device of the modulation to described optical signalling.
