LISLE, IL, Sep 23, 2026 – Molex’s new VersaBeam Mini connector combines expanded beam optics (EBO) with a 16-fiber, 3.5-by-9-mm footprint for AI data centers. Its Very Small Form Factor (VSFF) supports up to 3,456 fibers in a standard 1RU panel.
“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,” said Trevor Smith, general manager, Optical Connectivity, Molex. “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.”
Density and Service Access
VersaBeam Mini supports co-packaged optics, optical backbones and front-panel switch applications. Its dimensions address space constraints on equipment panels and inside chassis. Molex reports three times the density of its VersaBeam 16 connectivity.
Technicians can isolate, reroute or hot-swap individual groups of 16 channels. Molex describes this granularity as a ninefold reduction in “blast radius,” or the scope of affected connections.
An optional mass-insertion feature connects up to nine VersaBeam Mini connectors, totaling 144 fibers, with one push. This feature speeds initial rack deployment while preserving 16-channel service access and 1RU packing density.
Assembly and Maintenance
VersaBeam Mini uses the groove-based design of the 3M EBO Ferrule, eliminating guide pins and holes. The design supports robotic pick-and-place equipment during cable assembly. Fewer parts simplify supply management and reduce bill-of-materials (BOM) costs.
The connector joins Molex’s VersaBeam beam optics portfolio, launched in 2025. The technology expands the beam between connectors, reducing sensitivity to dust and debris.
Molex reports that reduced cleaning and inspection requirements can lower deployment and maintenance overhead by up to 85%. Technicians can service links without specialized optical equipment. It also cites laser eye safety as a feature to protect personnel during maintenance and upgrades.
Sampling is scheduled to begin in Q4, 2026. Production is planned for the first half of 2027.
