Product Highlights
*Next-Gen 16-Fiber VSFF Density As a premier 16-fiber VSFF (Very Small Form Factor) solution, the MMC-16 occupies significantly less space than standard MPO-16 connectors. This allows data center operators to triple their port density in 1U patch panels, making it the most efficient choice for high-density 800G and 1.6T network deployments.
*Elite Single-Mode Low-Loss Precision Equipped with premium Single-Mode Elite ferrules, the KEXINT 25519 guarantees a maximum insertion loss of ≤ 0.25dB. This industry-leading performance is vital for maintaining strict power budgets and low latency in high-speed optical links and AI training clusters.
*Purpose-Built for AI & 800G Infrastructure: This connector is specifically optimized for the massive I/O bandwidth requirements of AI GPU clusters and hyperscale fabrics. It provides seamless connectivity for the latest OSFP and QSFP-DD 800G transceivers, helping to eliminate data bottlenecks in modern high-performance computing (HPC) environments.
*Superior Mechanical Jacket Crimp Reliability: The specialized Jacket Crimp mechanism is engineered for 2.0mm to 2.5mm round cables, providing exceptional mechanical retention and pull-out protection. This robust design ensures long-term stability and fiber integrity, meeting the most rigorous carrier-grade durability standards.
*Compact 28mm Boot for Enhanced Airflow The ergonomic 28mm (1.1") short boot design is perfect for crowded server cabinets. It not only saves valuable depth but also significantly improves airflow and thermal management, ensuring that high-density equipment remains cool and operational under heavy workloads.
