Abstract
To establish direct electrical connections between two OSFP-XD transceivers, their connectors' footprints are specially aligned on opposite sides of a PCB board. The high-speed signal pads of the two footprints are precisely defined and connected through PCB traces and vias, according to specific configurations. The two OSFP-XD electrical connectors are then individually soldered onto their respective footprints. As a result, the electrical high-speed signals from the transceivers are directly connected via the specially defined connections in the shortest distance possible when the transceivers are plugged into their respective OSFP-XD connectors.
