Furukawa Electric Starts Mass Production of 13,824-Count Multi-Core Optical Fiber Cable
Furukawa Electric announced in March 2026 the start of mass production of a 13,824-count multi-core optical fiber cable featuring one of the world's highest fiber densities, designed for hyperscale data centers supporting AI and cloud services .
Key Specifications:
Parameter | Rating |
|---|---|
Fiber Count | 13,824 |
Cable Diameter | Less than 40mm |
Transmission Capacity | Double that of existing cables |
Technology | Rollable ribbon (intermittent connection-type) |
Connector Support | VSFF (Very Small Form Factor) |
Key Features:
High density: Uses rollable ribbons that intermittently connect 16 thin fibers with 200μm diameter to increase fiber density .
VSFF connector support: Contributes to smaller, higher-density connections .
Indoor/outdoor capability: Enables GPU clusters connecting multiple data center buildings .
Production Capacity:
The No. 2 plant at Mie Works, specialized for ultra-high count multi-core optical fiber cable, commenced full-scale operations in February 2026 .
Production capacity has more than doubled compared to FY2023 .
The new cable is part of the Lightera brand, Furukawa Electric's global optical solutions business launched April 1, 2025 .
This development addresses the need for increased fiber density and transmission volu
