An optical waveguide module (10, 110, 410, 510, 510, 710, 710') comprising: a. an optical light guide having opposite first and second planar surfaces (24, 26) extending between a first side edge and a second side edge, the optical light guide including one or more optical pathways extending between the first and second side edges (28, 30); b. one or more first edge connectors, each first edge connector having a first adapter port to interface with a first fiber optic plug and having a first alignment feature opposite the first adapter port; and c. one or more second edge connectors, each second edge connector having a second adapter port to interface with a second fiber optic plug and having a second alignment feature opposite the second adapter port; characterised by: the first alignment feature of each first edge connector enabling passive alignment of the first adapter port with the one or more optical pathways in a first direction parallel to the first side edge; the second alignment feature of each second edge connector enabling passive alignment of the second adapter port with the one or more optical pathways in a second direction parallel to the second side edge; wherein the first alignment feature of each of the one or more first edge connectors includes at least one alignment protrusion that engages with a corresponding first notch in the first side edge of the optical light guide; and wherein the second alignment feature of each of the one or more second edge connectors includes at least one alignment protrusion that engages with a corresponding second notch in the second side edge of the optical light guide. a. an optical light guide having opposite first and second planar surfaces (24, 26) extending between a first side edge and a second side edge, the optical light guide including one or more optical pathways extending between the first and second side edges (28, 30); b. one or more first edge connectors, each first edge connector having a first adapter port to interface with a first fiber optic plug and having a first alignment feature opposite the first adapter port; and c. one or more second edge connectors, each second edge connector having a second adapter port to interface with a second fiber optic plug and having a second alignment feature opposite the second adapter port; the first alignment feature of each first edge connector enabling passive alignment of the first adapter port with the one or more optical pathways in a first direction parallel to the first side edge; the second alignment feature of each second edge connector enabling passive alignment of the second adapter port with the one or more optical pathways in a second direction parallel to the second side edge; wherein the first alignment feature of each of the one or more first edge connectors includes at least one alignment protrusion that engages with a corresponding first notch in the first side edge of the optical light guide; and wherein the second alignment feature of each of the one or more second edge connectors includes at least one alignment protrusion that engages with a corresponding second notch in the second side edge of the optical light guide.
