  • Patent number: 10432339
    Abstract: A process of assembling an optical receiver module that receives a wavelength multiplexed signal is disclosed. The process includes a step of sequentially mounting a wavelength selective filter (WSF), a prism, a mirror, and first and second optical de-multiplexers (o-DeMuxes) each on the carrier. The WSF transmits a first wavelength multiplexed signal but reflects a second wavelength multiplexed signal. The prism includes first and second surfaces, where the first surface reflects the wavelength multiplexed signal toward the WSF, while the second surface receives a second wavelength multiplexed signal coming from the WSF. The mirror reflects the first wavelength multiplexed signal transmitting through the WSF. The first and second o-DeMuxes de-multiplex the first and second wavelength multiplexed signals.
