    Abstract: Embodiments herein relate to optoelectronic transceivers with power management. An optoelectronic device may include a photodetector, a loss of signal (LOS) detector coupled with the photodetector, and a re-timer coupled with the LOS detector, wherein a component of the re-timer is to be disabled in response to a detection by the LOS detector that an optical signal has not been received for a predetermined time period. In some embodiments, the LOS detector is coupled with a driver disable input of the re-timer and a driver component of the re-timer is to be disabled. In some embodiments, a clock data recovery circuit, a transmit module re-timer and modulator, and/or a laser may be disabled. In various embodiments, components may be re-enabled in response to detection that an optical signal is being received and/or an electrical signal is received for optical transmission. Other embodiments may be described and/or claimed.

    Abstract: In embodiments, an apparatus to predict failure of a laser is presented. The apparatus may include a memory to store a reference model of bias current change for a laser as a function of time and temperature, one or more sensors to detect: temperature, elapsed operating time and bias current of the laser, and a processor communicatively coupled to the memory and to the one or more sensors. The processor may be to calculate an actual bias current change ΔIA at a current laser temperature, and an expected bias current change ΔIE, based at least in part on the reference model and an average operating temperature, subtract ΔIE from ΔIA, and if the difference is greater than a pre-defined value α, output a signal. Related methods and non-transitory computer-readable media may also be presented.
