Abstract: An optical transceiver includes electrical inputs that each correspond to a selected port of a number of network ports and a selected network lane of the selected port. The optical transceiver includes optical transmitters organized in groups to optically transmit data received at the inputs over a plurality of optical transmission fibers to which the groups correspond. The optical transceiver includes multiplexers corresponding to the transmission fibers. Each multiplexer is to wave-division multiplex the data transmitted by the transmitters within the group corresponding to the transmission fiber to which the multiplexer corresponds. The optical transceiver includes hardware logic to differently map the inputs to the transmitters according to a selected mode of a number of switchable modes corresponding to different data transmission bandwidths.

Abstract: 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.

Abstract: A switch includes a plurality of ingress ports, a plurality of egress ports, and a plurality of buffers comprising a buffer coupled to each ingress port, egress port pair. An ingress port is to determine a plurality of potential egress ports for a packet. The ingress port is to select an egress port of the plurality of potential egress ports based on congestion of the corresponding buffers coupled to the ingress port and to each of the plurality of potential egress ports. The ingress port is to place the packet into the corresponding buffer coupled to the ingress port and the selected egress port.
