The present disclosure is directed to an optical device including a circuit board, an optical network and a lens kit. The circuit board has a mounting surface, and the optical fiber network is coupled to the circuit board opposite the mounting surface. The optical network includes two or more optical waveguides arranged in layers. A via extends through the mounting surface and into the optical network. The lens kit includes at least two lens pucks. At least one lens puck has a reflective element. The lens pucks are arranged to correspond with at least some of the optical waveguides. The lens kit is adapted to be inserted within the via and to reflect light traveling along an axis of the via into the optical network. The present disclosure is also directed to the lens kit and methods of making the lens kit and the optical device.
