Technology to tackle the massive increase in traffic and power consumption In order to solve the social issue of the massive increase in traffic at data centers and the accompanying increase in power consumption, Co-Packaged Optics (CPO), On Board Optics (OBO), and the IOWN proposed by NTT have been developed.

As data centers evolve, optical connection technology is also advancing rapidly. In particular, the spread of next-generation technologies such as Co-Packaged Optics (CPO) and On-Board Optics (OBO) has created a demand for optical connectors with higher performance and improved heat resistance. To meet this need, Hakusan Inc....

Towards realizing high-density wiring in next-generation data centers As the evolution of optical communication technology accelerates, the demand for higher speeds and larger capacities in data centers is increasing. To meet this demand, Hakusan continues to develop cutting-edge optical connector technology. In this article, we will introduce in detail the "reduced cladding MT Ferrule" that is at the core of this technology...

What is the optical waveguide technology that supports high-speed, low-latency optical communications? As demand for high-speed data communications in data centers and high-performance computing (HPC) fields surges, optical waveguides have become an essential technology. In particular, on-board Optical Interconnect (On-B…

Introduction: Technological innovation supporting "data center optical connection" in the AI era With the rapid advancement of AI technology, the amount of data communication in "data centers" is increasing dramatically. In particular, new technologies such as "CPO (Co-Packaged Optics)" and "OBO (On-Board Optics)" (...

In the implementation of Co-Packaged Optics (CPO), one of the key points of discussion is how optical interconnects should be realized in terms of their physical configuration. In particular, the choice between a detachable interface and a direct-to-board (non-detachable) implementation has a significant impact on assembly feasibility and scalability for volume production.
