Intel Is Using Lasers To Help Meet AI Demands On Data Centers
How does the OCI chiplet transmit data?
The OCI chiplet transmits data using light instead of electricity, through a process called optical signaling. Laser light travels through fiber optic connections, allowing processors to communicate over longer distances, almost 100 times longer than copper cables.
What additional features does the OCI chiplet include?
The OCI chiplet includes a single Intel Silicon Photonics Integrated Circuit (PIC) with on-chip DWDM lasers and SOAs, and an advanced node CMOS electrical integrated circuit (EIC) with all the electronic devices required to form a complete optical I/O subsystem46. It can be co-packaged with next-generation CPU, GPU, IPU, and other Systems-On-Chip (SOCs) with high bandwidth demand2.
Will Intel's OCI be compatible with other vendors' processors?
Yes, Intel's OCI will be compatible with most processors, including those from other vendors like Nvidia and AMD. Intel plans to work with the ecosystem to ensure interoperability and make sure that its photonics chip can communicate with photonics chips from other vendors.
