144-Fiber Self-Cleaning Low-Loss Connector

CommScope’s FastSelfClean connector features 9 rows of 16 fibers with a V-groove design. The fibers are concealed until they pass through an active cleaning mechanism at the time they are mated.

FastSelfClean 144-Fiber Connector

CommScope is introducing FastSelfClean, a high-density fiber connector that the company says provides exceptionally low insertion loss thanks to V-groove fiber seating, along with a self-cleaning capability that actively cleans fiber endfaces with each insertion.

“As designed, FastSelfClean connector technology will enable faster deployment of scale-up and scale-out networks in AI data centers by facilitating the connection of an entire rack-scale system in a 1RU panel, requiring only 24 physical connections to serve 3,456 fibers,” the company said when announcing the product, which it plans to release in 2027. “Deployment time will also be reduced thanks to the connector design’s self-cleaning capability that actively cleans fiber endfaces with each insertion, virtually eliminating routine fiber inspection and cleaning at installation, a unique benefit over ferrule-based connectors.”

The initial release will be a 144-fiber connector, which comprises 9 rows of 16 fibers each. The company also plans to offer customizable, stackable units of 8, 12, or 16 fibers.

“To optimize optical matching and provide ultra-low loss, the adapter uses V-grooves to prevent lateral or angular movement during mating, which requires up to 75% less mating force than standard multifiber connectors,” CommScope explained. Thanks to that V-groove technology, lab tests of prototypes produced consistent <0.25 dB insertion loss (0.1dB typical) and >55 dB return loss (>70dB typical), which CommScope characterized as “substantially better than available from either ferrule-based or lensed connector options.”

The connector’s self-cleaning capability comes from the fact that the fibers “are concealed safely inside a shroud until mated via a stackable alignment engine,” the company continued. “The fibers pass through an active cleaning mechanism in the process of connection that automatically washes the fiber endfaces,” not only for the initial connection, but for subsequent connections as well. This design “virtually eliminates the need for routine inspection and cleaning at the time of installation,” CommScope said, adding that lab-prototype tests using the Telcordia GR-326 Arizona dust process “reveal no significant increase in attenuation or reflectance was observed after the dust exposure, and no time-consuming inspection or cleaning required at any point in the process.”

Thanks to the combination of density (3,456 connections fitting in 1RU and requiring just 24 clicks) and the elimination of cleaning and inspection, CommScope estimates using FastSelfClean will reduce installation time by as much as 98.5%.

“CommScope innovation continues to deliver creative new technology to address the growing challenges faced by high-density data centers, particularly AI factories,” said Rocky Colapietro, general manager of CommScope’s data center business. “FastSelfClean technology will meet the need for faster, more-reliable deployment while also providing exceptional density and low-loss performance, enabling fewer people to deploy more connections, more reliably, in less space, and in much less time.”

The company’s head of research and development, Erik Gronvall, added, “FastSelfClean technology combines high density with exceptionally low optical loss in a robust connector design. As the high-performance computing industry evaluates integrating optics into servers and switches to increase bandwidth and reduce power consumption, new requirements are emerging for optical connectivity within rack-scale systems. FastSelfClean is uniquely positioned to address these evolving interconnect standards.”
