  • Patent number: 10484121
    Abstract: A receiver optical module is disclosed where the receiver optical module includes a coupling unit, an optical de-multiplexer, and an optical attenuator. The coupling unit secures an optical fiber. The optical de-multiplexer de-multiplexes a wavelength multiplexed optical beam that is provided from the optical fiber and multiplexes optical signals. The optical attenuator attenuates the wavelength multiplexed signal. A feature of the receiver optical module is that the optical de-multiplexer has a plurality of multi-layered dielectric films each pass one of the optical signals and has a rectangular shape with a shorter side and a longer side; while, the optical attenuator provides a shutter that is movable along the longer side of the multi-layered dielectric films.

  • 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.

  • Patent number: 10324875
    Abstract: Provided are a data processor, and a control system, in which an interrupt controller and an event link controller are adopted. The event link controller responds to a generated event signal to output a start control signal for controlling start of an operation of a circuit module. The circuit module is able to generate an event signal. The event link controller generates the start control signal according to the correspondences between event signals and start control signals which are defined by event control information. The links between the event signals and start control signals can be prescribed by the event control information. Therefore, operations of circuit modules prescribed by such links can be controlled sequentially. The control neither involves save and return processes by CPU as in the interrupt processing, nor needs priority level control as executed on competing interrupt requests.

  • Patent number: 10261273
    Abstract: An optical module to receive Rx-light from a single optical fiber and to transmit Tx-light to the single optical fiber is disclosed. In the optical module, the Rx-light enters a photodiode (PD) via a shortest path within a coupling block that provides surfaces constituting the path. The Tx-light emitted from a laser diode (LD) travels around a WDM filter within the coupling block. Both the Rx-light and the Tx-light enter the WDM filter at an acute angle. The lens to concentrate the Rx-light on the PD and to collimate the Tx-light is precisely aligned with respective devices mounted on a printed circuit board (PCB).

  • Patent number: 10090934
    Abstract: An optical receiver module that receives a wavelength-multiplexed optical signal is disclosed. The optical receiver module includes a first lens, an optical de-multiplexer, second lenses, and photodiodes. The first lens forms a beam waist of the wavelength-multiplexed optical signal output therefrom. The optical de-multiplexer de-multiplexes the wavelength-multiplexed optical signal into optical signals depending on wavelengths thereof and is installed so as to make optical paths for respective optical signals different from each other. The second lenses concentrate the optical signals onto the respective photodiodes. In the optical receiver module, the beam waist of the wavelength-multiplexed optical signal is set in a halfway between a longest path and a shortest path from the first lens to the second lenses.
