Advanced packaging (3D and chiplets)

What is the technology called that mounts optical transceiver components close to switch ICs and the like in the same package, shortening electrical wiring to reduce power?

  1. ACo-packaged optics (CPO)
  2. BBGA
  3. CQFP
Show answer and explanation

Answer: A. Co-packaged optics (CPO)

In data centers, as traffic grows, the power needed to transmit electrical signals over long distances has become a problem. CPO places optical transceiver components in the same package as switch ICs and the like, shortening the distance signals travel electrically and reducing power. It is one of the technologies integrating photonics and electronics.
