Abstract:
A system and method are disclosed to characterize and correct for the effects of IQ skew and insertion loss in a coherent optical transmitter. The coherent optical transmitter receives a digital data signal including in-phase (I) and quadrature (Q) components and generates corresponding first and second dither signals. The first dither signal may be combined with the I component and the second dither signal may be combined with the Q component to generate I and Q combined signals, which may be converted into I and Q analog waveforms. An optical signal may be generated corresponding to the I and Q analog waveforms for transmission over an optical fiber. The IQ skew and/or insertion loss for the coherent optical transmitter may then be calculated based on the optical signal using the disclosed dither tone processing techniques in order to correct IQ skew and/or insertion loss impairment.

Claim (Index 10):
The coherent optical transmitter of  claim 9 , wherein the processor comprises:\n a digital signal processor configured to produce the I and Q components of the digital data signal; a first digital-to-analog converter configured to convert the I component of the digital data signal into the analog I signal; and a second digital-to-analog converter configured to convert the Q component of the digital data signal into the analog Q signal.
