Revolutionize your AI network infrastructure with KEXINT’s 16-Fiber MMC to 8x LC Duplex harness cable, the definitive solution for high-density 800G and 1.6T data center migrations. This precision-engineered breakout cable features the next-generation VSFF (Very Small Form Factor) MMC-16 connector, allowing for a seamless transition from high-radix switch ports to LC-based distribution frames or transceivers with unmatched space efficiency.
Utilizing premium OS2 Single-Mode fiber and an Elite 0.35dB Max ultra-low-loss design, it ensures superior signal integrity for long-reach transmission. The OFNP Plenum-rated jacket meets the strictest fire safety standards for high-performance computing (HPC) environments. Designed for scalability and reliability, this harness cable is the ideal choice for massive AI clusters and hyperscale data centers requiring high-speed, high-density optical interconnects without compromising performance.
Product Description
MMC-16 F to 8 x LC Duplex Harness, APC to UPC, 16F, OS2, OFNP, 0.35dB, Jumper Polarity
The MMC fiber cable is equipped with an MMC connector, a Very Small Form Factor (VSFF) multi-fiber optical connector designed to terminate single-mode and multimode fiber cables up to 2.5mm in diameter. It employs novel TMT ferrule technology harmonized with the MT/MT-16 alignment structure. Individual connector access in the most extremely dense connector environments is easily accomplished using revolutionary DirectConec™ push-pull boot technology.
The harness aggregates multiple LC duplex connectors into an MMC-16 connector, streamlining infrastructure and helping optimize both space and network reliability. Therefore, MMC connectivity enables solutions that minimize the space required across multiple applications, including structured cabling, high-fiber-count data center interconnects, and high-bandwidth applications.

Features
3x Cabling Density over the MPO Format
The VSFF MMC connectors offer significant space savings, which help provide approximately three times the cabling port density over the MPO format.

Superior Workmanship Guarantees Stable Transmission
Bend insensitive fiber paired with high-performance US Conec MMC connectors delivers reliable connectivity for dense data center and carrier-grade applications.

Proven TMT Ferrule Technology
The TMT ferrule format is compliant with IEC 61755 and 61754 precision alignment structures for MT and MT-16 ferrules, ensuring precision polishing and mechanical integrity for repeated insertions and extractions.

Plenum Jacket, The Highest Fire Safety-Rated
The OFNP (plenum) jacket is safe for plenum air spaces and compatible with both unrated and OFNR (riser) rated applications.

Tested to Telcordia GR-1435
The MMC cable meets the Telcordia GR-1435 standards and covers the performance, tests, and quality requirements, seamlessly integrating with industry-standard infrastructure by adhering to a strict quality assurance program.
