Product Description
MMC-16 to MMC-16 Jumper, F to F, APC, 16F, OM4, 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.
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 performance, testing, and quality requirements, seamlessly integrating with industry-standard infrastructure through a strict quality assurance program.
