Molex has introduced VersaBeam Mini, an ultra-compact 16-fiber Expanded Beam Optical (EBO) connector designed to address space, thermal and maintenance challenges in high-density AI and hyperscale networks. The company announced the product on September 21, building on its existing VersaBeam EBO interconnect family.
VersaBeam Mini packs 16 fibers into a 3.5 x 9 mm footprint, which Molex says is a 3x density improvement over its standard VersaBeam 16 connectivity. That allows network architects to scale up to 3,456 fibers within a single 1RU panel. The connector is aimed at space-constrained applications including co-packaged optics, optical backbones and front-panel switch designs.
The 16-fiber granularity gives a 9x reduction in "blast radius," letting technicians isolate, re-route or hot-swap individual 16-channel lanes rather than larger fiber bundles. Molex also offers an optional mass-insertion feature that lets technicians engage up to 9 connectors, or 144 fibers, with a single push to speed up initial rack deployment.
Trevor Smith, general manager of Optical Connectivity at Molex, said: "As optical densities per rack grow exponentially, network architects are hitting hard physical walls in both scale-up GPU clusters and scale-out network fabrics... With VersaBeam Mini, we are providing a 'less is more' solution that pairs a VSFF footprint with zero-touch EBO technology, delivering less contamination risk, reduced downtime and a smaller blast radius without needing specialized technical expertise."
The connector's zero-touch EBO design, which expands the beam between connectors to reduce sensitivity to dust and debris, is intended to cut deployment and maintenance overhead by up to 85% compared with traditional fiber connectors. Limited customer sampling is set to begin in the fourth quarter of 2026, with general production slated for the first half of 2027. Molex is showcasing the product at the ECOC 2026 conference in Malaga, Spain, running September 21–23.
