The CPO JDF plans to release three documents focused on different elements of Co-Packaged Optics (CPO): the optical module, the External Light Source (ELS), and the CPO assembly (covered here). This collection of documents is intended to provide guidance to vendors pursuing Co-Packaged Optics (CPO).

Apr 1, 2024 · The A-type CPO is characterized by the chip and optical module being completely standardized and independent components, co-packaged on a PCB substrate. The distance between the optical engine and the chip is within 10cm, and the oDSP is eliminated.

Sep 16, 2022 · There are major differences between NPO and CPO. NPO: The ASIC chip of its switch is packaged, which contains Die and ASIC packaging substrate. The optical engine is also packaged, with a complete photoelectric signal processing process. This is the concept of …

Mar 28, 2025 · Illustration of traditional switch I/O vs. CPO integrated design . Why CPO Matters . The growing demands on data centers have exposed the limitations of traditional interconnects ... Signal Integrity: High-speed signals degrade rapidly over PCB traces, requiring complex re-timers and DSPs that add latency and cost. Rack Density: Every port adds ...

Feb 23, 2022 · We explain co-packaged optics (CPO), why they're important for data centers and networking, and the photonics engineering tools needed to expand adoption.

Jun 14, 2023 · Co-packaged optics (CPO) is an innovative technology that has gained significant attention in electronics and optical communication. This article aims to provide a comprehensive overview of co-packaged optics, highlighting its advantages and applications.

Jul 15, 2021 · Co-Packaged Optics (CPO) technology is designed to enable more extensive scale and faster integration by placing the electro-optical conversion process as close as possible to the computing, switching, or ASIC chip to achieve higher bandwidth and energy efficiency.

CPO, Co-packaged optics (CPO) is the co-packaging of chips and modules by assembling the switching chip and the optical engine in the same socketed slot. Figure 1 CPO Co-Packaging.

Feb 13, 2025 · With the growing demand for high-performance computing (HPC), artificial intelligence (AI), and data communication and storage, new chip technologies have emerged, following Moore’s Law, over the past few decades. As we enter the post-Moore era, transistor dimensions are approaching their physical limits. Advanced packaging technologies, such as 3D chiplets hetero-integration and co-packaged ...

Feb 24, 2025 · “Linear CPO will definitely save more power than LPO as the channel between electrical and optical die is extremely small in CPO,” said the OIF team. Meanwhile, LPO should be able to run initially from a half to a full meter — plenty to get from one part of the PCB to the other. But it may also be improved to run many meters, making it ...
