This DataPort contains supporting data of paper entitled Graph Representations for programmable photonic circuits for the Journal of Lightwave Technology. All unreachable nodes for the first graph are tested in the undirected graph with arbitrary negative weight. Unphysical paths are found on all 21 nodes. These same terminal nodes are validated in a directed graph with and without artificial nodes representing the same optical port overlapping each other.
