A shuffle assembly for a computing device comprises at least one chassis waveguide shuffle block having a plurality of chassis inputs and a plurality of chassis outputs, and having a plurality of optical waveguides formed therein connecting the chassis inputs to the chassis outputs in a desired chassis shuffle arrangement. The shuffle assembly may further comprise at least one line card waveguide shuffle block having a plurality of line card inputs, at least one of the plurality of line card inputs, a plurality of line card outputs, and a plurality of waveguides formed therein connecting the plurality of line card inputs to the plurality of line card outputs in a line card shuffle arrangement. At least one optical ribbon cable may couple the at least one chassis waveguide shuffle block to the at least one waveguide shuffle block.
