“We are now partnered with the hyperscaler to deploy this in a network,” says Manish Mehta, vice president of marketing and operations optical systems division, Broadcom. “This is a huge step for co-packaged optics overall.”
The Chinese hyperscaler will use Broadcom’s 25.6Tbps Tomahawk 4 Humboldt, a hybrid design where half of the chip’s input-output (I/O) is optical and half is the chip’s serialisers-deserialisers (serdes) that connect to pluggable modules on the switch’s front panel.
