224G scale-up cable backplanes have a challenging electrical budget which has limited them to a half rack of span, forcing GPU and switch ICs to be physically located at the back of trays.

To solve these issues, we have introduced Blue Heron, a multiprotocol retimer which enables full recovery of a 40+dB 224G link.

With Blue Heron, system integrators can architect rack-scale cable backplanes as well as flexible tray placement of GPUs and switch ICs to support AI scale-up applications.
