  • Patent number: 8532495
    Abstract: A method performed by a networked device for energy efficient operation of an optical transceiver of the networked device is described herein. It is determined whether a port control of the networked device is enabled to operate in an energy efficient state. Where the port control is enabled to operate in the energy efficient state and an absence of a valid receive energy from a link partner is determined, a laser transmitter of the optical transceiver is pulsed by asserting and de-asserting a control signal.
    Type: Grant
