Abstract: An optical transceiver can be calibrated using an internal receiver side eye scan generator, and calibration values (e.g., modulator values) can be stored in memory for recalibration of the optical transceiver. The eye scan generator can receive data from the transmitter portion via an integrated and reconfigurable loopback path. At a later time, different calibration values can be accessed in memory and used to recalibrate the optical transceiver or update the calibrated values using the receive-side eye scan generator operating in loopback mode.

Abstract: A microcontroller can interact with external ASICs using a multi-serial peripheral interface. The ASICs and the microcontroller can be included in an electrical device or an optical-electrical device. The microcontroller can implement the interface to access the registers of the different ASICs in bulk interactions, including a bulk status request, bulk configuration setting, and bulk data reads.
