Legrand Launches Chroma Link™: Color-Indexed Hyper-Density Fiber System Featuring SENKO SN®-MT Connectivity

Built with SN®-MT connectivity from センコーアドバンストコンポーネンツ, the system simplifies fiber management while supporting the density demands of AI-driven data centers.

Hudson, MA – March 17, 2026 – センコーアドバンストコンポーネンツ, a global leader in high-density optical connectivity, has collaborated with Legrand, the global specialist in electrical and digital building infrastructures, on the launch of Chroma Link™, a color-indexed fiber optic cabling system designed to simplify the deployment and management of hyper-dense AI and machine-learning networks. Chroma Link will debut at the OFC Conference 2026.

As AI workloads drive connector density to unprecedented levels, traditional patching methods have become a critical bottleneck. Current installation processes for a single hyper-dense application can consume up to a week of labor due to the complexity of manually tracing individual connections. Chroma Link addresses this inefficiency by enabling technicians to stop following cables and start following color.

Chroma Link is the first solution on the market to feature a patent-pending color-indexing system that runs throughout the entire ecosystem. The system matches colored ports on the enclosure with identical color coding on trunks and harnesses, allowing installers to instantly identify paths from the ​​server rack to the leaf switch​, or the leaf switch to the spine, and beyond, as meshing continues to grow in complexity to meet increased demand. By transforming the patch field into a straightforward visual roadmap, the system significantly reduces the risk of human error and minimizes the time required for deployment and maintenance.

“Chroma Link introduces a new way of thinking about fiber management,” said Sabrina Snyder, VP/General Manager of Data Infrastructure at Legrand. This is the first system to apply true color indexing across an entire fiber ecosystem, and it fundamentally reshapes how technicians navigate hyperdense environments. “

 

HighDensity Connectivity Powered by SENKO

A key enabler of Chroma Link’s performance is SENKO’s SN®-MT connector technology, engineered specifically to support rapid deployment in hyperdense architectures. While today’s transceivers remain based on Base-8 fiber interfaces, SNMT® connectors intelligently aggregate these connections into Base-16 connector interfaces, reducing the number of physical mating cycles required during installation.

This approach preserves compatibility with existing transceiver architectures while delivering higher connection efficiency and faster installation at the patch field, where time, accuracy, and repeatability are critical.

“High-density connectivity is no longer just about fitting more fibers into less space, it’s about making complexity manageable at scale,” said Phil Ward, Director of Strategic Marketing, SENKO Advanced Components. “With SN®-MT technology at the core of Chroma Link, we’re enabling faster, cleaner deployments while maintaining the Base8 architectures required at the transceiver. This collaboration with Legrand demonstrates how connector innovation and system level design together can simplify the future of AI networks.”

Key Features of Chroma Link Include:

• Turnkey system delivery: Supplied as a fully integrated package of enclosures, trunks, and harnesses to streamline planning and installation.
• Support for extreme fiber density: Enables up to 2,304 fibers in 1RU enclosures and 4,608 fibers in 2RU enclosures, maximizing whitespace efficiency in modern data centers.
• SN®-MT high-density connectors from SENKO: Aggregates Base-8 architectures into Base-16 interfaces to reduce installation time while preserving transceiver compatibility.
• Rapid installation capability: A 4-gang SN®-MT clip allows installers to connect 64 fibers simultaneously, dramatically accelerating deployment in high fiber environments.
• Standards based safety and familiarity: Uses industry standard TIA598D color coding, ensuring immediate recognition and safe handling by trained technicians.

The Chroma Link solution launches with singlemode configurations, with multimode options planned.
