Cable Associates Achieves US Conec MMC® Manufacturing Certification for Hyperscale AI Connectivity

Cable Associates is proud to announce its certification, in collaboration with US Conec, to manufacture MMC® connector assemblies. This achievement expands Cable Associates’ high-density fiber optic portfolio to include the complete line of VSFF (Very Small Form Factor) assemblies, strengthening its position as a leading manufacturing partner for next-generation optical interconnect solutions.

MMC® connectors enable ultra-high-density fiber connectivity by significantly reducing connector size while maintaining reliable, low-loss optical performance.

We collaborate closely with customer engineering teams to support product improvement initiatives, while also delivering comprehensive assembly and testing documentation as needed.

Designed for modern data center, AI, and HPC architectures, MMC® improves airflow, simplifies cable management, and allows more fibers to be deployed in the same physical space. Its scalable design supports future growth without infrastructure redesign, while factory-terminated assemblies ensure consistent, repeatable performance at scale.

MMC® Fiber Optic Connector Assemblies

Ultra-Dense Connectivity for the Next Generation of Networks
Smaller footprint. Higher density. Future-ready performance.

MMC® (Miniature Multi-Fiber Connector) assemblies redefine high-density fiber connectivity. Designed for environments where space, bandwidth, and scalability are critical, MMC® assemblies deliver exceptional optical performance in a dramatically reduced form factor—enabling next-generation architectures without compromise.

Why MMC®

As networks evolve toward AI, machine learning, and ultra-high-speed interconnects, traditional connectors become a limiting factor. MMC® was engineered to remove that constraint.
Key advantages:

Up to 2× the density of traditional multi-fiber connectors
Optimized for short-reach, high-fiber-count architectures
Precision alignment for consistent low loss
Designed for automated and high-volume deployments

MMC® enables more connections in less space—without sacrificing reliability.

Connector & Assembly Architecture

MMC® connector assemblies feature a miniaturized multi-fiber interface with precision-guided ferrules and robust mechanical retention, ensuring repeatable performance even in ultra-dense installations.
Assembly features include:

Compact MMC® connectors (male or female)
High-precision ferrule geometry
Optimized end-face polish for low insertion loss
Secure push-pull engagement for high-density panels
Factory-terminated and tested assemblies

The result: predictable optical performance in environments where access and space are limited.
