Our passive optical subassembly (POSA) uses Corning’s free-space-optics wavelength division multiplexing (WDM) platform to deliver optical mux/demux functionality directly inside standard or customized small-form-factor platform transceivers. Our unique substrate-based POSA and glass-block POSA are designed to seamlessly integrate with your specific input and output interface.
