  • Apparatus, systems, and methods for optical channel management
    Patent number: 11595146
    Abstract: An apparatus includes a reconfigurable optical add/drop multiplexer (ROADM) having an input port to receive a first optical signal from a second device. The ROADM also includes a first wavelength selective switch (WSS), in optical communication with the input port, to convert the first optical signal into a second optical signal, a loopback, in optical communication with the first WSS, to transmit the second optical signal, and a second WSS, in optical communication with the loopback, to convert the second optical signal to a third optical signal and direct the third optical signal back to the second device via the input port.
    Type: Grant
    Filed: May 2, 2022
    Date of Patent: February 28, 2023
    Assignee: Juniper Networks, Inc.
    Inventors: Gert Grammel, Ajay Kachrani, Patrick Michael McEachern
