Scale Up, Simplified. Accelerate Every Connection.

AI-enabled data centers are pushing deployment timelines faster than ever, while making every connection more critical. MMC® Connectors with PRIZM® TMT Ferrule technology are designed to help reduce cleaning requirements, limit the risk of contamination-related performance issues, and simplify deployment in real-world data center environments.

Using a lens-based, expanded-beam optical interface, PRIZM TMT technology helps maintain predictable performance with little to no cleaning required in many deployment conditions. The compact MMC connector design also supports high-density, blind-mate-enabled connectivity, helping operators scale AI infrastructure faster, cleaner, and with greater confidence.

How PRIZM® Technology Works

Physical contact:

Traditional connectors rely on pressure-mated ferrules, requiring meticulous cleaning and alignment.

Physical Contact

Contact free:

PRIZM Technology uses collimation lenses that expand the light beam between connectors, decreasing sensitivity to contaminants and the need to clean.

Ready for the Next Generation of AI Architecture

Ready for the Next Generation of AI Architecture

As AI architectures evolve from front-plane patching to full backplane integration, density requirements multiply. PRIZM TMT's blind-mate architecture is built for this transition. It delivers industry-leading fiber density in environments where power, cooling, and connectivity must all coexist. As the only lensed connector platform spanning front-plane patching, mass insertion, and high-density blind-mate backplane integration, PRIZM TMT supports the evolution of AI infrastructure without requiring a new connectivity strategy at every stage.

Beginning with 16-fiber ferrules and designed to scale to 32-fiber configurations, the PRIZM TMT platform provides a clear path to the higher fiber counts required by next-generation GPU clusters and AI fabrics. The same MMC-compatible footprint and connector ecosystem help expand density without architectural disruption as requirements grow.

MMC Connectors with PRIZM TMT Ferrules are part of the Corning® GlassWorks AI™ family that supports the performance, density, and speed required by next-generation AI workloads.

FAQs

  • What makes PRIZM® TMT Ferrule technology different from traditional physical-contact connectors?

    Traditional physical-contact connectors rely on direct fiber contact and extremely precise alignment. PRIZM® TMT Ferrule technology uses a lens-based, expanded-beam optical interface that creates a no-contact connection between connectors. This design reduces sensitivity to contamination, minimizes cleaning and inspection requirements, and simplifies deployment for AI data centers and hyperscale environments.

  • How does PRIZM® TMT combine mass insertion speed with individual connector serviceability?

    PRIZM® TMT enables mass insertion for faster deployment while preserving access to individual connections. Each connector within a ganged assembly can be removed, inspected, or reseated independently, without impacting adjacent ports. This reduces the fault footprint, simplifies maintenance, and helps keep high-density AI networks running with minimal disruption.

  • How does PRIZM® TMT help support higher network density?

    PRIZM® TMT enables up to three to six times the density of traditional MPO connectivity within the same footprint. Combined with MMC connectors and scalable 1×16 and 2×16 configurations, it helps maximize fiber density in server racks and supports the growing connectivity demands of AI data center architectures.

  • How does PRIZM® TMT help deliver predictable optical performance across large-scale AI networks?

    As AI networks scale to thousands of optical links, consistency becomes just as important as optical performance. PRIZM® TMT lensed connectors are designed to deliver a tight, predictable insertion loss distribution across first-attempt, no-clean, no-inspection mating. By reducing performance variability and minimizing high-loss outliers, PRIZM TMT supports predictable network design, faster deployment, and lower operational risk.

  • Does PRIZM® TMT sacrifice optical performance for easier deployment?

    No. PRIZM® TMT delivers 0.5 dB insertion loss, providing best-in-class optical performance among lens-based optical connectors. It helps eliminate the traditional tradeoff between expanded-beam connectivity and network performance, enabling data center operators to deploy faster while maintaining reliable, high-speed optical links.

  • How does PRIZM® TMT help simplify manufacturing and support production at scale?

    PRIZM® TMT is designed to reduce manufacturing complexity through passive alignment principles. By eliminating active alignment at critical process steps, the design helps simplify automation and enables more manufacturing operations to occur in parallel. The result is improved production efficiency and a manufacturing approach that can scale more effectively as demand grows.
