The MMC connector combined with the TMT ferrule technology offers the most compact optical connectivity solution while achieving exceptional performance. The reduced TMT ferrule size and windowless design allows for the environmental performance to be significantly improved over the legacy MT ferrule geometry. With its symmetrical shape and need for minimal termination epoxy, the design contributes to its overall product stability during exposure to environmental regimens such as TIA 568 and GR-1435, including uncontrolled environments. The reduction in ferrule size also provides a path to improved precision fiber alignment and lower overall insertion losses.

• Reduced Size​
• Symmetrical​
• Less Epoxy​
• Improved Precision Alignment

The MMC connector further supports the improved performance with its precision rail structure. This optimized pre-alignment eliminates the guide pins from stubbing the ferrule guide holes in the mating process, minimizing wear and debris generation. With this pre-alignment design, debris is minimized. The precision rail design also enables simplified polarity management for the MMC cabling ecosystem.​​

• Precision Rail Structure​
• Precision Plug to Port Fit
• Reduced Debris​
• No Ferrule to Guide Pin Stubbing

The latch design of the MMC connector uses a single latch and is located away from the optical interface of the TMT ferrule. This design reduces debris generation around the ferrule end face during mating/unmating.​​​

• Latching Structure Separated from Optical Interface
• Single Latch​
• Reduced Debris​
• Simple Insertion/Extraction

The TMT ferrule design with its smaller footprint, reduced epoxy cavity and symmetrical shape provides a path to lower insertion losses and better stability during environmental exposures. These improvements eliminate barriers to improve beyond IEC 61755-1 Grade B definitions. The data below represents actual QC insertion loss results from >1 million production ferrules:
