MMC Connector is a next-generation Very Small Form Factor (VSFF) solution designed to enable ultra-high-density optical connectivity for hyperscale data centers, AI infrastructure, and advanced optical architectures.
As network environments move beyond traditional MPO systems, higher density, improved airflow, and greater deployment flexibility are essential. The compact MMC footprint allows significantly increased port density per rack unit while maintaining reliable multi-fiber performance.
Sanwa Technologies delivers precision-engineered MMC connectors built on advanced molding, high-accuracy machining, and comprehensive optical evaluation technologies. Our integrated manufacturing system ensures stable quality and scalable production to meet growing global demand.
