  • Patent number: 12353199
    Abstract: A communication apparatus includes a communication unit, a power supply unit, a temperature monitoring unit, and a control unit. The communication unit communicates with an additional apparatus. The power supply unit supplies power to components mounted in the communication apparatus. The temperature monitoring unit monitors a temperature in the communication apparatus to detect presence or absence of a temperature abnormality. In a case where the temperature monitoring unit detects the temperature abnormality, the control unit performs power supply stop processing of stopping the power supply from the power supply unit to at least some of the components. Furthermore, the control unit stops or decreases communication of the communication unit in a case where the temperature monitoring unit detects the temperature abnormality.

  • Publication number: 20240007776
    Abstract: An aspect of the present invention is an optical communication system in which an optical line terminal and an optical network unit are connected by an optical communication line, in which when receiving a first activation signal from the optical line terminal in a sleep state, the optical network unit executes activation processing for transition from the sleep state to an activation state and notifies the optical line terminal of an activation time that is a time required for executing the activation processing, and the optical line terminal transmits the activation signal at a time of transmission of second and subsequent activation signals, and then the optical line terminal starts data transmission to the optical line terminal after elapse of the activation time a notification of which has been given from the optical network unit.
