Business Details

Composed of two businesses: the Information & Communications Solutions business (optical fiber, optical cable, optical-related components, network equipment, etc.) and the Energy Infrastructure business (power cables, industrial wires, power transmission/distribution components, etc.). Its primary customer base consists of domestic and overseas data center/AI-related markets and demand for domestic ultra-high-voltage underground cables and renewable energy applications, with manufacturing and sales handled by the global optical fiber and cable business organization under Lightera Holding and group companies such as Furukawa Electric Metal Cable Co., Ltd.

Recent Overview

Net sales and operating profit increased significantly due to rapid data center demand growth and M&A

In FY2026 (ending March 2026), the Infrastructure segment achieved net sales to external customers of ¥363,941 million (up 20.0% year on year) and operating profit of ¥21,439 million (up 276.1% year on year), a substantial increase in both revenue and profit. In the optical fiber and cable business, a unified global structure was established under the "Lightera" brand, and expansion of sales in North America contributed to results. Furukawa Fitel Optical Components Co., Ltd. (formerly Fujitsu Optical Components Limited) was made a subsidiary in April 2025, and Furukawa Electric Submarine Cable Co., Ltd. was made a subsidiary in July 2025. Meanwhile, the company transferred all of its equity interest in a Chinese subsidiary (Shenyang Furukawa Cable Co., Ltd.), streamlining an unprofitable business. Impairment losses of ¥1,581 million were recorded, mainly related to business assets in China and the United States.

Key Products

product
Optical Fiber & Optical Cable (Rollable Ribbon Cable, etc.)

A product group for data centers, led by rollable ribbon cable. Deployed under a unified global strategy under the new brand "Lightera." Progress is also being made in establishing an expanded sales structure in North America.

product
Optical Connecting Components & Optical Semiconductor Devices (MT Ferrules, DFB Laser Diode Chips, etc.)

Developing and expanding sales of high-value-added products such as MT ferrules and DFB laser diode chips. In April 2025, Fujitsu Optical Components Limited (now Furukawa Fitel Optical Components Co., Ltd.) was made a subsidiary, adding optical component products such as LN high-speed optical modulators.

product
Power Cables & Connecting Components

Manufacturing capacity and construction capability are being strengthened against a backdrop of steady demand for replacement of domestic ultra-high-voltage underground cables and submarine/underground cables for renewable energy. In July 2025, Furukawa Electric Submarine Cable Co., Ltd. was made a subsidiary, advancing efforts to strengthen HVDC cable manufacturing capacity.

product
Industrial Wires & Power Transmission/Distribution Components (Aluminum CV Cable, etc.)

Operated mainly through Furukawa Electric Metal Cable Co., Ltd. (formerly Furukawa Electric Industrial Wire Co., Ltd.). Focused on expanding sales of priority products such as aluminum CV cable and cable-equipped plug-in connectors. Pursuing synergy effects from the consolidation of the metal wire business (merger/absorption-type split of KANZACC).

product
Network Equipment, CATV Systems & Wireless Products

Regarding the CATV systems business, the company has resolved to conduct an absorption-type company split of the CATV business into Miharu Communications Co., Ltd. (to be renamed Furukawa Miharu Solutions Co., Ltd.), effective October 1, 2026, with plans to build a more efficient operating structure and a one-stop optical infrastructure provision system.

Growth Drivers

  • Increased demand for optical cables and optical-related components (rollable ribbon cable, MT ferrules, DFB laser diode chips, etc.) driven by the continued expansion of the data center and AI-related markets
  • Efficient and rapid decision-making in the optical fiber and cable business under the unified global strategy of the "Lightera" brand, along with establishment of a sales expansion structure in North America
  • Realization of photonics technology synergies through the acquisition of Furukawa Fitel Optical Components Co., Ltd. (world's top share in LN high-speed optical modulators)
  • Strengthening of HVDC cable manufacturing capacity and capture of submarine cable demand for renewable energy through the acquisition of Furukawa Electric Submarine Cable Co., Ltd.
  • Steady demand for replacement of domestic ultra-high-voltage underground cables and for submarine/underground cables for renewable energy
  • Consolidation of the metal wire business (integration into Furukawa Electric Metal Cable Co., Ltd.) to consolidate market areas, strengthen competitiveness, and maximize synergy effects

Risks

  • Integration risk during the transition period of the operating structure accompanying the global reorganization of the optical fiber and cable business (Lightera structure)
  • Profit volatility risk due to variation in profitability of individual projects in the Energy Infrastructure business (there is a track record of recording product warranty provisions for large power projects)
  • Impact on raw material costs and net sales due to fluctuations in copper ingot prices and foreign exchange rates
  • Risk of earnings deterioration due to economic slowdown and intensifying price competition in the Chinese market (largely resolved through the transfer of equity in Shenyang Furukawa Cable Co., Ltd.)
  • Risk of impairment losses arising in the Infrastructure segment (impairment losses of ¥1,319 million recorded in FY2026 (ending March 2026) on business assets in China and the United States)
  • Risk of delays or cost overruns in HVDC cable manufacturing facility investment (scheduled to commence operation around 2030)
