Abstract

A multiplexing device includes two facing-but-spaced apart optical transmitting plates, with optical reflective filters in facing contact with outer surfaces of the optical transmitting plates to define a reflective beam path therebetween. Light transceivers are associated with each of the optical reflective filters. The optical transmitting plates have greater indices of refraction than the central medium between them, so that the beam path has a low angle of incidence to the optical reflective filters but a higher angle in the central medium.
