Fujikura Introduces the Revolutionary 4000-Core Optical Fiber Cable

Fujikura Ltd. has made a significant leap in optical fiber technology with the launch of its new 4000-core SWR®/WTC® optical fiber cable, aimed specifically at the burgeoning data center market in Japan. This groundbreaking innovation is a result of the increasing demand for higher communication data volumes driven by the proliferation of generative AI and cloud services.

A Breakthrough in Fiber Optic Technology

The 4000-core SWR®/WTC® cable integrates an advanced multi-core fused structure, featuring either 16 or 8 cores in a fixed intermittent configuration, specifically designed to meet the needs of Japan's data centers. This fiber optic ribbon cable (referred to as Spider Web Ribbon® or SWR®) is part of Fujikura's proprietary technology for an ultra-thin, high-density fiber optic cable (Wrapping Tube Cable® or WTC®). Notably, it holds the title of the highest core count optical fiber cable available for domestic data centers.

Addressing Space Constraints

The demand for greater core counts in fiber optic cables stems from the increased traffic data surrounding the telecommunications landscape. Previously, Fujikura had supplied 2000-core and 3000-core cables to the domestic market, but the shift towards higher core capabilities became imperative due to the constraints posed by existing underground conduits, which require that the maximum outer diameter of the fiber optic cable not exceed 24mm.

To address these challenges, the new 4000-core SWR®/WTC® cable has been engineered to maintain a maximum outer diameter of just 23mm while preserving mechanical properties and optical performance comparable to that of the 3000-core cables. It offers a dual product line of both 16-core and 8-core SWR® variants, capable of supporting both fusion splicing configurations effectively.

With the introduction of 16-core splicing connections, there is a notable improvement in the efficiency of the splicing process and fiber management at termination racks. This not only streamlines installation procedures but also contributes significantly to an overall reduction in construction time.

Complete Product Lineup

Fujikura intends to expand its product lineup with the launch of specialized closures to coincide with the debut of the 4000-core SWR®/WTC® cable. This supplementary equipment will enable more efficient utilization of existing infrastructure while employing the high-density cables for constructing robust communication networks.

Commitment to Innovation

Fujikura is dedicated to advancing engineering technology in communication networks through its SWR®/WTC® series. The company aims to contribute to building an advanced information society, both domestically and internationally, by delivering high-quality, innovative technologies and product development.

About SWR® and WTC®

SWR® (Spider Web Ribbon®) and WTC® (Wrapping Tube Cable®) are registered trademarks of Fujikura Ltd., representing a state-of-the-art fusion of flexibility and high-density implementation capabilities within fiber optic technologies. The SWR® technology features a unique design that adheres single-core optical fibers intermittently, allowing for enhanced flexibility while supporting high-density configurations. Conversely, WTC® encases the SWR® within a straightforward structure using a tape-wrapped design, allowing it to utilize existing conduits more effectively and significantly reduce installation timelines compared to traditional fiber optic cable designs.
