  • TUNING OPTOELECTRONIC TRANSCEIVERS IN OPTICAL NETWORK
    Publication number: 20200244371
    Abstract: A method of tuning optoelectronic transceivers in an optical network may include powering on a first optoelectronic transceiver, setting a channel wavelength of the first optoelectronic transceiver, transmitting a first request command from the first optoelectronic transceiver through the optical network to a second optoelectronic transceiver, and non-iteratively changing a channel wavelength of the first optoelectronic transceiver until a second request command is received from the second optoelectronic transceiver. The second request command may indicate to the first optoelectronic transceiver that the channel wavelength set by the first optoelectronic transceiver is able to travel through the optical network between the first optoelectronic transceiver and the second optoelectronic transceiver.
