The MMC12 apc patchcord /fiber jumper represents the next generation of ultra-high-density optical connectivity, purpose-built for AI-driven and hyperscale data center environments. Based on a Very Small Form Factor (VSFF) design, it delivers over 3× higher port density than traditional MPO solutions, enabling more efficient space utilization and scalable network expansion. Featuring an advanced TMT (miniaturized MT-style) ferrule, the MMC connector ensures precise fiber alignment and low insertion loss, making it ideal for high-speed optical transmission. It is widely used in high-density structured cabling, AI cluster interconnects, data center interconnect (DCI), and emerging co-packaged optics (CPO) architectures, offering a compact, high-performance solution for next-generation data center networks.




The MMC connector features a very small form factor footprint, enabling over 3x higher port density compared to traditional MPO connectors. This density advantage allows deployment of the same number of optical ports in less than one-third of the space, or increases optical port capacity per rack unit by more than 3x. In addition, the compact interface size creates more working space around each optical port, improving cable management, airflow efficiency, and overall operational convenience.


In large data center campuses, high fiber count cables—up to 6,912 fibers—are commonly deployed between buildings for aggregation layer connectivity. Traditionally, these links require bulk cable installation and field fusion splicing, especially in conduit pathways or space-constrained indoor routes.
With its reduced form factor, MMC enables factory-terminated assemblies that can be directly installed in constrained pathways—eliminating complex field splicing, accelerating deployment, and minimizing data center downtime.


The ganged MMC connector is specifically engineered to address the critical challenges of maximizing density while ensuring seamless deployment in structured cabling systems. Featuring a compact design and advanced precision alignment, the ganged MMC connector enables faster installation and simplifies complexity in high-density environments. Offering significantly higher port density, it allows network designers to optimize rack space while ensuring flexibility for future scalability. With its innovative design, the MMC connector streamlines connectivity, reduces installation time, and empowers networks to scale efficiently, overcoming density constraints.
The MMC connector is available in 1x12, 1x16 and 2x12 variants on the market. And NADDOD currently offers it in 16F TMT ferrule format online.
MMC solutions enable 0.35dB low insertion loss performance, and their angled physical contact (APC) design translates to superior return loss.
MMC‑12 and MMC‑16 connectors share the same US‑Conec VSFF mechanical platform, enabling cross‑compatible mating within MMC‑series patch panels. Please note that only matching fiber‑count channels will carry optical signals; unused channels should be properly covered with dust caps to prevent contamination.
Jumper Polarity is designed for patch‑cord‑to‑patch‑cord direct interconnections, matching channel‑to‑channel mapping for short‑reach cross‑connect links. Trunk Polarity is intended for high‑density trunk‑cable deployments that require cross‑channel mapping when connecting patch panels. This MMC‑12 jumper is configured for Jumper Polarity for standard rack‑to‑rack and patch‑panel‑to‑patch‑panel applications.
