  • Patent number: 11477038
    Abstract: A certificate transfer system includes a first certificate management host and a certificate transfer management host. The first certificate management host is configured to generate a first certificate, sign an electronic device with the first certificate, and transmit a first Internet address to the electronic device to complete a certificate-issuance operation. The certificate transfer management host is configured to store a transfer device list and a second Internet address. When the first certificate management host receives the first certificate issued by the electronic device, the first certificate management host verifies that the first certificate is correct and determines that if the first certificate matches one of the certificates in the transfer device list, the first certificate management host returns the certificate transfer management host address to the electronic device.

  • Patent number: 11038588
    Abstract: When performing failure prediction on an optical transceiver, the output optical power and an operational current of a transmission optical sub-assembly in the optical transceiver are recorded during the operation of the optical transceiver. A first ratio is acquired by dividing the average slope of the operational current recorded at a current time period by the average slope of the operational current recorded at an earlier time period. A second ratio is acquired by dividing the absolute average value of the slope of the output optical power recorded at the earlier time period by the absolute average value of the slope of the output optical power recorded at the current time period. When it is determined that the product of the first ratio and the second ratio is greater than a threshold value, a failure notification including life prediction information is provided.
