Broadcom will be discussing this topic of “ Solving the Interconnect Density Bottleneck in 51.2T Switches” on May 4th. The link is below

2 years ago Tom Mika  highlighted in a conference call that we have transcripts for that the next generation of Broadcom’s Switch will double from 25.6 TB/sec to 51.2 TB/sec and the technology will need to adapt. The Optical Interposer can address these issues. This is what he said.

“The 400G Light Bar, that has a trademark associated with it, is also a product that we think is applicable to the co-packaged optics market. And briefly I’ll just say that what’s happening in that market is that Broadcom’s latest switch that operates at 25.6 Tb/sec. Once it goes to the next generation that pretty much doubles that speed… Much of the energy that is available to power the switch blade and the server racks is going to be used up. Something has to happen. And what has to happen is all of the compensating circuits that are currently in a switch blade that compensate for the loss of power and the timing of the signal within that box when the electrons go from the switch to the back side of the blade… to the backplane… All of those circuits that also take energy have to come out. And we think we are in a very good position to offer products in that area because of the technology that we’ve got in the optical interposer. We think we can come much closer to the switch itself and provide some flexibility and lower power requirement solutions in the market.”

Will Broadcom use the Optical Interposer to address this bottleneck ? I sure hope so.

One thing that is for sure is that Broadcom is aware of the Optical Interposer. We learned recently that POET’s AI customer Celestial AI has a supplier agreement with Broadcom to build the company’s products.Also one of their board members Alexis Bjorlin worked for Broadcom for the last 3 years before recently moving to Facebook.. Vivek is also on this board.
