Proficium, Inc.

Proficium is a Union City, California optical connectivity company that designs, manufactures, and tests the cables and transceivers that move data inside hyperscale and AI data centers. Founded in 2003 by Dan Miranda, it supplies OEM-compatible optical transceivers (400G, 800G, and 1.6Tb/s), DAC/ACC/AOC copper and optical cables, fiber assemblies, and InfiniBand interconnects validated against gear from Arista, Cisco, NVIDIA, and Juniper. An early mover in AI/ML cluster networking since 2019, the company was acquired by private equity firm Mill Point Capital in 2024 to scale with surging data center demand.
