Molex Shrinks Optical Connectors for Denser AI Data Center Networks

Molex, a global provider of electronic connectivity and interconnect solutions, has introduced VersaBeam Mini, a compact optical connector designed for high-density AI and hyperscale data center networks.

The connector uses 16-fiber Expanded Beam Optics (EBO) in a 3.5-by-9-mm footprint. Molex says the design provides three times the density of its VersaBeam 16 technology and supports as many as 3,456 fibers in a standard 1RU panel.

VersaBeam Mini is intended for applications including co-packaged optics, optical backbones and front-panel switches. Its 16-fiber granularity also lets technicians isolate or replace individual 16-channel connections rather than disrupting larger groups of links.

An optional mass-insertion mechanism can connect nine VersaBeam Mini units, representing 144 fibers, in a single operation. Molex is also designing the connector for automated manufacturing, including robotic pick-and-place assembly.

The expanded-beam design reduces sensitivity to dust and debris by expanding the optical beam between connectors. Molex says its approach can reduce deployment, inspection, and maintenance work by up to 85 percent. The design also incorporates laser eye-safety protections for technicians.

For AI infrastructure teams, optical connectivity is becoming a significant physical design consideration as GPU clusters require more bandwidth between accelerators, switches and racks. Higher connector density can help infrastructure vendors increase network capacity without proportionally increasing front-panel and chassis space.

Limited customer sampling is scheduled for the fourth quarter of 2026, with general production planned for the first half of 2027.
