US Conec, Corning Incorporated, Fujikura and Sumitomo Electric Lightwave Announce Multi-Source Framework for PRIZM® TMT Expanded Beam Ferrules and Associated MMC Connectors

HICKORY, NC, March 11, 2026 – US Conec, Corning, Fujikura and Sumitomo Electric Lightwave announce separate agreements to broaden the MMC VSFF (Very Small Form Factor) platform to include expanded beam optics. The PRIZM^® TMT ferrule delivers next-generation expanded beam technology in the prevalent TMT format, enabling use in the widely adopted MMC connectivity platform. Corning, Fujikura and Sumitomo Electric Lightwave are each enabled to produce the US Conec designed ferrule and associated MMC connector components and will provide PRIZM^® TMT based cabling solutions. The agreements further expand on the rapidly growing high density optical connectivity supply chain infrastructure by addressing the scale, density, and operational demands of new, AI factory link architectures.

Featuring precision micro holes for passive fiber to lens alignment, PRIZM^® TMT achieves a low-loss expanded beam solution with debris insensitivity, reducing time spent cleaning and troubleshooting during installation. The expanded beam PRIZM^® TMT ferrule reduces the mating force by 70% compared to physical contact ferrule technology enabling high-density mass insertion configurations without compromising performance. The PRIZM^® TMT precision passive alignment structure enables scalable, automatable termination processes which leverage existing high-volume manufacturing infrastructure. The PRIZM^® TMT ferrule is suitable for any existing or future high density connector embodiments designed for multi-fiber ferrules.

PRIZM^® TMT and MMC based solutions will be on display at OFC in Los Angeles from March 17-19, 2026, at Corning booth 1739; Fujikura/AFL booth 4907; Sumitomo Electric Lightwave booth 1658; US Conec booth 1938.
