US Patent 11177877 Data transfer between electrical-optical devices

Systems and methods for performing data transfer between first and second electrical devices are provided. One method may include electrically coupling the first electrical device to a first electrical-optical (E-O) device via a first plurality of electrical lanes, electrically coupling the second electrical device to a second E-O device via a second plurality of electrical lanes, optically coupling the first and second E-O devices via a plurality of optical lanes, and transferring data therebetween via a first optical lane. The method may include monitoring one or more parameters associated with an optical transmitter of the first optical lane, and comparing each parameter to a respective threshold. Responsive to the comparison, the method includes commencing transfer of data between the first and second E-O devices via a second optical lane, and terminating transfer of the data between the first and second E-O devices via the first optical lane.
