High-Density MMC Connectivity for AI Infrastructure
AI deployments require significantly more fiber than traditional compute environments. As GPU density increases, so does the number of fiber connections that need to be accommodated and managed within each rack.
As structured cabling scales to support those fiber volumes, it requires more rack and panel space. In high-density AI environments, every rack unit matters. Where power and cooling allow, space needed for fiber management can mean less room for GPUs and other active equipment.
And the pressure will continue to grow. As future GPU generations drive even higher fiber densities, more rack space will be required for fiber management, while deployments still need to be fast, manageable and repeatable at scale.
The challenge is increasing fiber density without increasing the infrastructure footprint at the same rate.
A Smaller Connector for Higher-Density Fiber
MMC is a very small form factor multi-fiber connector designed for high-density optical infrastructure.
Its compact footprint allows significantly more fiber connections to be accommodated within limited panel and rack space, helping prevent passive connectivity from becoming a constraint as AI and HPC environments scale.
For data centers managing rapidly increasing fiber volumes, the benefit is straightforward: more connectivity in less space.
The Benefits of Higher-Density MMC Connectivity
Increasing GPU density creates a simple challenge: more fiber needs to fit into the same physical environment.
Traditional connectivity can consume increasing amounts of rack and panel space as fiber counts grow. MMC helps condense that connectivity, making it easier to introduce high-density structured cabling without sacrificing valuable space.

Your Biggest MMC Questions Answered
MMC is a very small form factor multi-fiber connector designed to provide greater fiber density within a smaller connectivity footprint.
MMC can deliver up to three times the density of MPO connectivity within the same footprint, allowing more fiber connections to be accommodated in limited rack and panel space.
As GPU density increases, so does the number of fiber connections required to support it. MMC helps data centers accommodate those growing fiber volumes without proportionally increasing the space dedicated to passive connectivity.
Not necessarily. MMC can be used within the fiber cabling channel to increase density while leveraging MPO via hybrid jumpers to connect to transceivers. MPO will continue to be the typical choice when densities are less extreme.
Structured cabling can make large fiber volumes easier to organize and manage. MMC allows that structured approach to be delivered at much higher density, helping reduce the rack space required for passive connectivity.
