MMC Connector

 A pioneering Very Small Form Factor (VSFF) multi-fiber optical connector, revolutionizing optical connectivity with its innovative TMT ferrule technology and DirectConec™ push-pull boot design.

DMSI International and US Conec have jointly announced an expansion of their collaborative endeavors. DMSI International, in its role as an MMC Collaborator, will embark on the production of new cable assemblies equipped with MMC connectors.
