Mixx Joins EBO MSA, Pushes 0.2 dB Connector for Near-Package Optics

SAN JOSE – November 04, 2026 -- Mixx Technologies has joined the Expanded Beam Optics Multi-Source Agreement (EBO MSA) and the Open CPX MSA as a contributing member, pitching its SxCTM connector at 0.2 dB typical fiber-to-fiber loss for the near-package optics step in hyperscale AI data centers.

SxC connector holds loss under 0.5 dB at up to 24,576 fibers per rack unit

The SxCTM connector, launched in September, is the connectivity layer of Mixx's HBxIOTM platform. It is rated at under 0.5 dB maximum loss. In a single Open Compute Project rack unit it carries up to 24,576 fibers, four times the fiber density of MMC. Its optical structures are formed at wafer scale, which lets fibers sit in a two-dimensional array.

SAN JOSE, Calif. – September 06, 2026 -- Mixx Technologies, Inc. has launched the SxCTM Connector, an optical connector capable of terminating up to 24,576 fibers in a single rack unit, a density the company says is four times greater than MMC-VSFF, the highest-density connector platform currently qualified for deployment.

Connector density becomes the bottleneck for co-packaged optics deployment

Mixx, a venture-backed deep-tech firm building co-packaged optics (CPO) for hyperscale AI infrastructure, said existing connector families cannot support the fiber density that next-generation inference workloads require. A 400T switch brings thousands of fibers out of a single box, exceeding what pluggable transceivers can support at the front panel. Mixture-of-experts and agentic AI workloads demand high radix — the number of endpoints a single node can reach — to minimize latency and reduce switching layers, transceivers, and cables.
