Description

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 extremely dense connector environments is easily accomplished using 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. The product is also referred to as MMC Patch Cord.
