Enhancing Optical Connectivity: Mixx Technologies Champions Reliability in Near-Package Optics

In the ever-evolving realm of hyperscale AI infrastructure, connectivity plays a pivotal role. Mixx Technologies, Inc., a US-based company specializing in optical connectivity solutions, has recently made a significant statement in the industry concerning near-package optics. The organization's commitment to developing robust and reliable optical connectors is at the heart of their latest innovations, particularly the SxC™ Connector.

As members of the Expanded Beam Optics Multi-Source Agreement (EBO MSA) and contributors to the Open CPX MSA, Mixx emphasizes the critical nature of optical connectors in ensuring high-density optical performance. With an impressive low-loss characteristic of 0.2 dB typical fiber-to-fiber, the SxC™ Connector serves as a vital component of the HBxIO™ platform. This connector is specifically designed to address the intricate challenges of fiber density and termination typical in near-package setups, ahead of anticipated needs as the use of optics expands into the network infrastructure.

The SxC™ Connector's pioneering expanded-beam design effectively manages the link budget, which refers to the maximum allowable loss of laser power during data transmission from the emitter to the receiver. This ensures optimal functioning as every connection contributes to overall performance. As Mixx's CEO, Vivek Raghuraman, points out, “Each of those fibers crosses a connector, which is where the link budget is decided. Every recovered dB becomes architectural headroom, and ultimately, economic advantage.” This highlights the focus on reducing loss at every stage of transmission to build more efficient networks.

One of the pressing issues in the industry is termination – the crucial process of securing each fiber into its connector. As the fiber counts escalate, Mixx Technologies is tackling this bottleneck by integrating advanced practices that stem from semiconductor assembly techniques. Raghuraman states, “Termination grows with every fiber, and the industry has to address it before optics can scale inside the box. Scaling optics means measuring production in units per hour, not hours per unit.” Here, Mixx is taking the lead by standardizing the connector technologies across the signal chain, ensuring that the processes become streamlined and efficient.

The organization is not venturing blindly; it builds on the established standards trusted by hyperscalers, ensuring that the transition to an optical connectivity framework fits seamlessly into existing infrastructures. The initiative behind the Open CPX MSA involves standardizing sockets adjacent to the package, facilitating compatibility among modules sourced from multiple vendors. To support this, Mixx is developing an Open CPX module that combines the optical engine with a detachable SxC™ connector, allowing for individual testing and potential field replacements.

“The measure of a solution is whether a hyperscaler can confidently deploy it at scale,” Raghuraman explains. By enabling parts to be tested and replaced independently, the common-use Open CPX connector framework lays the foundation for hassle-free operations.

As the optical fiber expands deeper into network frameworks, the industry is responding to the heightened demands for greater integration, with near-package optics leading with innovative features. Unlike traditional physical-contact connectors that require manual cleaning for maintenance - an issue identified by the EBO MSA in which around 80% of network problems stem from cleanliness - the new designs leverage Expanded Beam Optics that minimizes direct contact. This innovative approach not only reduces the mating force by roughly 20 times but also greatly diminishes installation and clean times by up to 85%.

The EBO MSA, which originated in March 2026, emphasizes the development of open and interoperable standards for Expanded Beam Optics in AI-centric data centers. With over 60 members, including both suppliers and end-users, this collaborative framework is actively shaping the future of optical connectivity.

Looking ahead, Raghuraman states, “Hyperscalers are moving optics inside the box now. The EBO MSA is the start line where hyperscalers want us to be.” As upcoming protocols and standards get implemented, the focus remains on reliability and performance, with the SxC™ acting as a foundational product for high-density architectures not only inside the box but also at its boundary.
