The AI explosion continues to drive demand for high-performance accelerators and ultra-high fiber density in data centers. Consequently, the need for very small form factor (VSFF) connectors has significantly increased.
STL now offers multi-fiber cables pre terminated with MMC solutions; delivering 3 times the fiber capacity of traditional MPO solutions, less cable congestion and seamless scalability as speeds increase from 800G to 1.6T and beyond.
STL MMC connectors are now officially US Conec certified.
The Standard
Certified at Scale
To become US Conec MMC certified requires high quality manufacturing capability. STL now joins a select group of global manufacturers delivering MMC pre-terminated solutions at scale.
Vertically Integrated
STL manufactures its own glass preforms from which optical fiber is drawn and the fiber cable is manufactured. This vertical integration gives STL additional flexibility to supply during times of high demand.
An MMC (Mini Multi-fiber Connector) is a specialised, next generation optical fiber connector designed to fit multiple optical fibers into a footprint one third the size of a standard MPO (Multi-fiber Push-On) connector.
More fibers in the same footprint. Because MMC’s are small, network designers can deploy 3x the fiber density compared with standard MPO connectors. This allows a single rack unit of space to support hundreds more fiber connections, avoiding the need to build out costly new physical data center space.
The MMC belongs to the VSFF (Very Small Form Factor) connector family. It uses a much smaller ferrule (the component that holds the fiber strands) based on TMT (Tiny Multi-fiber Termination) ferrule technology.
AI servers draw a lot of power and get very hot, requiring huge amounts of power and air flow to keep them cool. Thick, bulky legacy cable bundles interfere with the flow of air, compromising cooling efficiency. MMC solutions are thinner, and take up significantly less volume, allowing for better air flow and cable management.
Modern AI clusters of accelerators require very high bandwidth and ultra-low latency. Data center networks are now being designed for data rates of 800G/1.6T and beyond. There is an associated increase in fiber connections that requires the space savings that MMC’s offer.
Co-Packaged Optics (CPO) switch technology is rapidly advancing, with commercially available CPO switches now integrating optical fiber paths directly onto the switch circuit substrate. By using MMC solutions, a significantly higher number of fiber ports are able to be positioned directly on the switch front-panel.
The MMC solution packs 12 fibers, and 16 fibers up to 24 fibers into a single VSFF ferrule, matching the breakout needs of 400G, 800G, and future 1.6T optical modules and beyond.

STL manufactures its own glass preforms; these are the glass cylinders from which all optical fiber is drawn. Owning the base of the supply chain is important, especially during times when fiber demand spikes.
This fiber independence enables STL to develop specialty fibers as we did with Multi-Core fiber (MCF), bend-optimised 200µm, 180 & 160µm formats ; these are the fiber technologies the next generation of AI GPU connectivity will be built on.
With 30 years of industrial-scale fiber manufacturing, STL has been the fiber backbone for network builders across Asia, North America, and Europe.
