NSG Group and Hakusan to Exhibit Jointly Developed Multi-Fiber Optical Connector for Immersion Cooling

03 Jun 2024

First in the World at COMNEXT

NSG Group and Hakusan Inc. are pleased to announce that they are exhibiting “Grin EB® Connector”, a multi-fiber optical connector for immersion cooling under joint development for the first time in the world at COMNEXT -2nd Next Generation Communication Technology & Solutions Expo to be held at Tokyo Big Sight from June 26, 2024.

With the recent spread of cloud computing services and AI, the volume of data communication is dramatically increasing, and the energy load for cooling servers and other equipment in data centers continues to rise in line with the increase in the volume of data communication. In this situation, immersion cooling technology*1, which cools server equipment by directly immersing it in a refrigerant liquid, has also been tested in Japan as a key technology for reducing power consumption in data centers due to its superior energy-saving performance, and the development of related peripheral technologies is also being rapidly progressed.

This product was developed in response to the growing need for optical connectors*2 for immersion cooling by taking both advantage of Hakusan's technology, which has the second largest share of the global market for MT ferrules*3, a multi-fiber optical connector component, and also the features of NSG Group’s ultra-fine lens (125µm, the same diameter as optical fiber), SELFOC® Micro Lens*4 that can be used even in refrigerant liquid.

While conventional optical connectors used in immersion-cooled equipment have possibility to have been plagued by communication failures due to contamination by refrigerant liquid, this newly developed product can ensure the quality of communication by the effect of beam expansion and collimation by the lens.

The outline of the exhibition is as followed. We look forward to seeing you at the exhibition.

*1 Immersion Cooling Technology

This is a technology that effectively cools equipment such as servers by immersing the entire device in a special liquid that does not conduct electricity and bringing the refrigerant liquid into direct contact with the device. Due to the dramatic increase in the volume of data communications and data centers, it is predicted* that by 2030 the world's power consumption for data communications will reach the equivalent of the annual power consumption in 2022, making the curbing of power consumption an urgent issue. Of the power consumed by these data centers, 30-40% is due to equipment cooling, and it is believed that energy savings can be achieved by cooling servers more efficiently.

*2 Optical Connector

Optical connectors are components used to connect optical fibers. It consists of a "connector body," a "ferrule" that fixes the fiber, and an "interlocking mechanism" that provides a mechanical connection between the connector body and the device. Multi-fiber optical connectors are also used to connect multiple optical fibers to ensure signal transmission quality and reliability in optical fiber communication systems. Multifiber optical connectors are generally available in 2-fiber, 4-fiber, 8-fiber, 12-fiber, and 24-fiber types, depending on the number of optical fibers.

*3 MT Ferrule

This is a key component of a connector called a multi-fiber optical connector that mechanically connects optical fibers together. The end face of the coffee bean-sized component has a fiber hole that can accommodate multiple optical fibers.

*4 125µm ultra-fine SELFOC® Micro Lens

This product is designed for the all-optical networking of communication infrastructure and immersion cooling technology that are being considered in the Beyond 5G era, where explosive increases in communication volume and network-connected devices are expected. By using a lens with a diameter of 125 μm, which is the same diameter as that of an optical fiber, the product will help reduce the size and performance of devices connecting optical fibers and individual terminals via optical signals, while at the same time making a significant contribution to energy-saving measures, which have been a concern in recent years.
