Abstract: Systems, devices, and methods are described herein for reducing a link bringup time period for optical switching between network devices. An example method of the present disclosure receives an indication of a reconfiguration condition associated with an optical switch communicatively coupled to an optical communication channel and based on the reconfiguration condition, selects first data associated with a storage device or second data associated with a pattern generator device for transmission to a first network device. Selecting the first or second data may be based on a digital logic signal that indicates whether data is actively received from the second network device via the optical communication channel or may be based on a defined schedule for reconfiguring the optical switch.

Abstract: An optoelectronic transmitter (10) includes an electro-optic modulator (12), digital driving circuitry (14), and feedback circuitry (30). The electro-optic modulator is configured to modulate an optical signal in response to an electrical drive signal. The digital driving circuitry is coupled to the electro-optical modulator and is configured to generate the electrical drive signal. The feedback circuitry is configured to measure a quantity indicative of a power level of the modulated optical signal produced by the electro-optic modulator, and to adapt a supply voltage to the digital driving circuitry in response to the measured quantity.
