Example methods and apparatus to implement an electrical/optical transceiver to facilitate data transfer are disclosed. An example apparatus includes an electrical transceiver lane to transfer data at a first bandwidth over an electrical link. The example apparatus also includes a plurality of optical transceiver sub-lanes to transfer data over an optical link. The example apparatus also includes a lane switch to dynamically map the electrical transceiver lane to the plurality of optical transceiver sub-lanes based on an analysis of the first bandwidth and the plurality of optical transceiver sub-lanes to accommodate the first bandwidth with at least a subset of the plurality of optical transceiver sub-lanes to transfer data between the electrical link and the optical link.
