US Conec, Hakusan, and Sanwa Technologies Announce Agreements to Multi-Source and Develop MMC Very Small Form Factor (VSFF) Connector and TMT Ferrule Solutions

Sanwa Technologies, Hakusan, and US Conec announce agreements to bolster industry supply of MMC VSFF (Very Small Form Factor) multi-fiber optical connector and ferrule components.

Sanwa Technologies will expand on their VSFF solutions of MDC duplex and MMC adapters by offering the industry acclaimed MMC multi-fiber connector embodiment. Hakusan Inc. will leverage their decades of expertise in low-loss MT technology to manufacture and supply the TMT ferrule in both x12 and x16 fiber variants. The agreements further expand on the rapidly growing supply chain infrastructure for state-of-the-art, high-density optical connectivity solutions.

Next generation hyperscale data center architectures have migrated away from traditional MPO cabling infrastructure to the higher density, enhanced functionality, rapid deployment, and improved performance of the MMC connector platform. In addition, emerging networking and server cluster technologies employing co-packaged and embedded optics are taking advantage of the higher densities of the MMC connector platform both internal to the equipment and as the optical I/O.

Comment from Akito Ishikawa, COO & CSO of SANWA Technologies:

"We are very excited to announce the expansion of our MMC VSFF Connector license and partnership with US Conec as SANWA continues our full commitment to the MMC and MDC VSFF technologies and the ecosystem. With addition of Hakusan in this partnership, leveraging their low-loss Multi-Fiber Ferrule manufacturing expertise, three companies will work together to rapidly expand the supply capacity to support the ever-rapidly growing market demands. SANWA is grateful to take part in this exciting collaboration with US Conec and Hakusan."

■Comment from Ryu (Tatsuki) Kimbara, Chief Marketing and Business Development Officer Hakusan:
