Legrand says it has launched Chroma Link, a color-indexed fiber optic cabling system aimed at hyper-dense AI and machine learning networks, and positioned it as a way to simplify fiber deployment as data centers push toward 800G and higher applications.
The pitch is operational: Legrand argues that traditional patching and tracing methods are turning into a labor bottleneck as connector density rises. In its announcement, the company says installation processes for a single hyper-dense application can take up to a week of labor because technicians must manually trace individual connections. Chroma Link is designed to replace that process with color-based identification across the patch field, so technicians “stop following cables and start following color,” according to the PR.
Legrand says Chroma Link uses a patent-pending color-indexing system that spans the full ecosystem, matching colored ports on the enclosure to identical color coding on trunks and harnesses. In practical terms, the company says that allows installers to identify connection paths “from the server rack to the leaf switch, or the leaf switch to the spine, and beyond.” Legrand frames the outcome as faster deployment and maintenance, with a lower risk of human error, by turning the patch field into a visual mapping system.
On density, Legrand lists up to 2,304 fibers in 1RU enclosures and up to 4,608 fibers in 2RU enclosures. The system uses SENKO SN-MT connectors, and Legrand says it “condenses” traditional Base-8 connections into Base-16 connectors to increase density per port and reduce deployment time. For installation speed, the PR also calls out a 4-gang clip for SN-MT connectors that lets installers connect 64 fibers simultaneously.
While the indexing approach is new, Legrand says it’s using industry-standard fiber color identification per TIA-598-D. The company says Chroma Link is launching with single-mode capabilities, and that multimode configurations will follow.
“This solution brings clarity to the patch field, giving installers a visual system that dramatically shrinks timelines, and makes hyper‑dense environments far more manageable,” said Sabrina Snyder, VP/General Manager of Data Infrastructure at Legrand.
