  • Dispersing data rate to mitigate electromagnetic interference
    Patent number: 11784717
    Abstract: A method in which a plurality of transmit signals are generated at data rates that are offset from each other to minimize detectable electromagnetic interference at a particular frequency. The method further includes converting each transmit signal to a corresponding optical transmit signal of a plurality of optical transmit signals for transmission via a corresponding channel of a plurality of channels of an optical network device and transmitting the plurality of optical transmit signals via respective ones of the plurality of channels for transmission on respective optical fibers.
    Type: Grant
    Filed: January 31, 2022
    Date of Patent: October 10, 2023
    Assignee: CISCO TECHNOLOGY, INC.
    Inventors: Jianquan Lou, Alpesh Umakant Bhobe, Hailong Zhang, Xiao Li, Guangcao Fu

  • Multiple port network device with differential ports for reduced electromagnetic interference at optical modules
    Patent number: 10999654
    Abstract: In one embodiment, an apparatus includes a plurality of optical module ports in communication with a physical layer device in a network device. Communication of signals from the physical layer device to the optical module ports is configured such that the signals received at the optical module ports adjacent to one another are at different phases to reduce electromagnetic interference associated with the optical module ports.
