<p>Methods, apparatuses, and systems for communication systems. One embodiment of the present invention is an optical communications system including a first group of transmitters producing a first spectral group containing at least two optical signals, wherein each of the signals In the first spectral group has a polarization orientation which is non-parallel to adjacent signals within the first spectral group. the system also includes a second group of transmitters producing a second spectral group containing at least two optical signals, wherein each of the signals in the second spectral group has a polarization orientation which is non-parallel to adjacent signals within the second spectral group, and wherein the polarization orientation of the first spectral group is independent of the polarization orientation of the second spectral group. The polarization orientation of signals within each spectral group may be, for example, orthogonal or other non-parallel orientations. The present invention also includes apparatuses and methods according to the present invention.</p> |
