One example includes an optical port-shuffling module. The module includes a plurality of inputs to receive a respective plurality of optical signals. The module also includes a plurality of outputs to provide the respective plurality of optical signals from the optical port-shuffling module. The module further includes a plurality of total-internal-reflection (TIR) mirrors arranged in optical paths of at least a portion of the plurality of optical signals to reflect the at least a portion of the plurality of optical signals to at least a portion of the plurality of outputs to shuffle the plurality of optical signals between the plurality of inputs and the plurality of outputs.
