1. A system for in-band spectral cross-talk monitoring, the system comprising:
a built-in self-test (BIST) and logic circuitry; and
a processor operatively coupled to the BIST and logic circuitry, a first micro ring modulator (MRM) associated with a first data packet (FD), and a second MRM associated with a second data packet (SD), wherein the processor is configured to:
receive, from the first MRM, a complement of the first data packet (FD), wherein the FD comprises second MRM spectral cross-talk data;
receive, from a second MRM, a complement of the second data packet (SD);
determine, using the BIST and logic circuitry, a spectral ordering of the FD and the SD based on at least the second MRM spectral cross-talk data and the SD; and
re-order, using the BIST and logic circuitry, the FD and the SD based on the determined spectral ordering.
