Stackable waveguide shuffle blocks and systems and methods of identifying same

A waveguide shuffle block assembly, comprising:

• a housing comprising a plurality of angled optical cable connector interface sockets;
• a waveguide shuffle block enclosed within the housing effectuating connectivity between at least two of a plurality of angled optical cable ferrule/connector interfaces corresponding to the at least two of the plurality of angled optical cable ferrule/connector interface sockets, wherein the waveguide shuffle block comprises a plurality of integrated circuits and at least one photonic integrated circuit comprising at least one wavelength coupler with which connectivity between the at least two of the plurality of angled optical cable ferrule/connector interfaces, wherein the at least one photonic integrated circuit comprises a plurality of filters and a plurality of modulators, each of the plurality of integrated circuits is operatively connected between a filter of the plurality of filters and a modulator of the plurality of modulators, wherein an optical signal output from each of the plurality of modulators has a wavelength that is shifted to another wavelength relative to a wavelength of an optical signal entering the waveguide shuffle block;
• and
• at least one retention mechanism maintaining the waveguide shuffle block assembly in a stacked formation with at least one other waveguide shuffle block assembly.
