US Patent 11018772 Optical communication circuits

Various apparatuses, circuits, systems, and methods for optical communication are disclosed. In some implementations, an apparatus includes multiple lasers that input an electronic signal. Each laser encodes and outputs a respective optical data signal based on the electronic signal. Each laser has a different configuration of one or more first optical parameters. A first selection circuit selects the respective optical data signal from one of the lasers. Multiple optical components configure second optical parameters of an input optical data signal. A second selection circuit inputs the selected optical data signal from the first selection circuit and provides the selected optical data signal to one of the optical components. A third selection circuit selects the optical data signal output from the one optical component.
