COMPANY PROFILE / OPTICAL COMMUNICATIONS & PHOTONICS

Fujikura
A cable maker that wires AI data centres by connecting light rather than emitting it

Fujikura is a wire and cable maker, yet in the year to March 2026 its Information and Communications segment alone posted sales of ¥653.0 billion and operating profit of ¥152.7 billion, earning about 80% of the company's total operating profit. What it sells is a complete "optical wiring kit": optical fibre, thin high-fibre-count cable, multi-fibre optical connectors, fusion splicers and even installation work. The simplest way to see the whole picture is that Fujikura is on the side that connects light, not a maker of parts that emit light or convert it to and from electricity, such as lasers or optical transceivers. This profile keeps the power cable, automotive parts and other businesses to a minimum and concentrates on what the company is putting into optical communications, who it is working with and where it is heading.

The one thing to grasp first

Companies involved in optical communications fall into three broad types: optical components & modules, chips & foundries, and network systems & carriers. Fujikura is on the optical components side, but its position differs from companies in the same category that make lasers, photodetectors or optical transceivers Sourced. The Annual Securities Report lists the main products of the Information and Communications segment as optical fibre, optical cable, telecommunication components, optical components, optical equipment, network equipment and construction work, and the company describes this as a total solution for building communication networks, spanning optical fibre cable, fusion splicers, optical connectors, optical components and telecommunications engineering. In other words, Fujikura is a company that supplies, as a complete set, the optical "wiring and connections" inside and outside data centres and between them. As more data centres are built for generative AI, the first thing that grows is the number of fibres and fibre counts, which puts the company in the position to benefit most directly.

2. The logo and how the name is written

The Fujikura logo is a trademark of the company. We have not recreated it with generated imagery; the image was taken from the official website and is placed here as img/fujikura_logo.png.

A note on names: the legal entity is Fujikura Ltd. It changed its trade name from Fujikura Electric Wire Corporation to the present name in October 1992. AFL Telecommunications LLC (AFL), which handles optical fibre cable, connectivity components and installation in the U.S., is a wholly owned subsidiary; its sales in the year to March 2026 were ¥355.3 billion, more than 10% of consolidated sales. "AFL" in this article refers to this subsidiary.

3. Where the company sits in the optical communications landscape

Three types of company in optical communications and photonics All of them are optical communications companies, yet where they handle light differs completely Optical components & modules Chips & foundries Network systems & carriers Sell parts to emit and detect light Make chips that connect to optics Build and run optical networks Lumentum / Coherent InnoLight / Ayar Labs, etc. NVIDIA / Broadcom TSMC / Intel, etc. NTT / Ciena Nokia / Cisco, etc. Mass-producing lasers, packaging Sell into switches and GPUs Long-haul and operations know-how Heavily reliant on big customers Often rely on others for optics Data-centre tech changes fast Fujikura sits far left, but it connects light with fibre, cable and connectors rather than emitting it It supplies fibre, fusion splicers and installation as a set, wiring inside, around and between data centres
Fig. 1 The three types of company involved in optical communications and photonics, and where Fujikura sits. The classification is our own, and the companies shown are examples drawn from those covered in this series Our calculation. Fujikura's placement is based on the main products of the Information and Communications segment given in the Annual Securities Report for the year to March 2026 (optical fibre, optical cable, telecommunication components, optical components, optical equipment, network equipment, construction work and others).

In terms of where in the optical chain it operates, Fujikura's main battleground is wiring inside data centres, DCI (Data Center Interconnect) links between data centres, and carriers' optical fibre networks. It is also developing optical fibre couplers for submarine cable repeaters Sourced. In CPO (co-packaged optics), which replaces short electrical links inside data centres with light, it is involved not as a maker of optical transceivers or chips but as a supplier of the polarisation-maintaining fibre used inside. This is exactly the "fibre linking the external light source to the chip" discussed in our explainer on co-packaged optics.

4. Scale (the group in brief)

The size of the group as a whole is covered in a single table Sourced.

Measure (¥ million)Year to March 2024Year to March 2025Year to March 2026
Consolidated net sales799,760979,3751,182,358
Consolidated employees (people)50,25451,26250,586
Consolidated R&D expenses--About 16,800 (¥16.8 billion)

Because the company discloses its optical communications figures as the Information and Communications segment, that segment is all we need to look at. The segment's figures, not the group's, are the focus of this article Sourced.

Information and Communications (¥ million)Year to March 2025Year to March 2026
Net sales (including inter-segment transactions)451,415653,172
Segment profit (operating profit basis)92,167152,729
Segment assets355,691481,414
Depreciation8,95611,207
Increase in property, plant, equipment and intangible assets15,37318,263
Employees (people, 31 March 2026)-15,199 (plus 706 temporary)
Our calculation: how much the optical segment carries the company

In the year to March 2026, the Information and Communications segment's sales to external customers of ¥652,977 million were 55.2% of consolidated net sales, and its segment profit of ¥152,729 million was 80.9% of group operating profit of ¥188,707 million Our calculation. The segment's operating margin was 23.4% (20.4% the year before), a level of profitability far removed from what is normal for a cable maker. By region, sales to customers located in the U.S. were ¥522.2 billion, 44.2% of consolidated net sales Our calculation. That is a group figure; no regional breakdown is disclosed for the Information and Communications segment alone.

5. Resources committed to optical communications and photonics

Four kinds of resource (people, money, outside investments and ties with public bodies) are set out below, as far as they could be confirmed in the Annual Securities Report and official announcements.

Type of resourceWhat it isCategory
People (dedicated organisation and staff)The Information and Communications segment has 15,199 employees (plus an average of 706 temporary employees, 31 March 2026), of whom 890 are at the parent company. Sakura Works, which has optical fibre manufacturing facilities, has 677 and Suzuka Works 95. R&D is handled by the New Business Creation and R&D division and by development departments within each business divisionSourced
Money (R&D)R&D expenses in the Information and Communications segment were ¥11.5 billion (year to March 2026), 68.5% of consolidated R&D of ¥16.8 billion (the percentage is our calculation)Sourced
Money (capital expenditure)A next-generation plant for optical fibre and SWR® costing about ¥45 billion is being built at Sakura Works. In March 2026 the company decided to invest up to ¥300 billion in Japan and the U.S. (¥40 billion in Japan, up to ¥260 billion in the U.S.). A new SWR® plant costing about ¥10 billion started operating in February 2025. Investment to raise MT ferrule capacity to about 1.7 times the FY2024 level has been carried outSourced
Outside investments and joint venturesUS Conec Ltd. (U.S.), a maker of multi-fibre optical connector components, is an equity-method affiliate; an official release states that it is a joint venture of Corning, Fujikura and NTT Advanced Technology. Others include Fujikura Fiberhome Opto-Electronics Material Technology in China (a consolidated subsidiary with 60% of voting rights) and Nanjing Wasin Fujikura Optical Communication (an equity-method affiliate)Sourced
Agreements with public bodiesThe mid-term plan materials state that on 28 October 2025 the company signed a framework agreement with the U.S. Department of Commerce and was selected as a supplier of optical fibre cable (SWR®/WTC®) in the field of strengthening U.S. generative AI infrastructureSourced
Joint research with public research institutesWith NICT (Japan's National Institute of Information and Communications Technology) and Astrodesign, developed a 3 mm-diameter cable holding eight four-core multi-core fibres and deployed it in a working uncompressed 8K video system (announced March 2025)Sourced
Acquisitions in optical communicationsThe Annual Securities Report for the year to March 2026 mentions no new acquisitions in optical communicationsNot confirmed
Public funding in optical communications (NEDO and others)No selection for subsidies or commissioned projects in optical communications and photonics appears in the primary sources we checked (the NEDO selection of August 2025 relates to quantum computing and is outside the scope of this article)Not confirmed
Reading the amounts

"Up to ¥300 billion" is the ceiling of the investment decided, not what was spent in the year to March 2026. The fixed assets actually added in the Information and Communications segment in that year came to ¥18,263 million Sourced. According to the mid-term plan materials, the ¥40 billion Japanese and up-to-¥260 billion U.S. projects are planned to ramp up in stages from 2030, which suggests that most of the spending will fall in FY2027 or later Not yet confirmed.

7. What comes next

INFORMATION AND COMMUNICATIONS SALES TARGET¥1,050 billion in FY2028¥719.4 billion in FY2026, then ¥880 billion in FY2027
INFORMATION AND COMMUNICATIONS PROFIT TARGET¥285 billion in FY2028About 90% of the group target of ¥315 billion
OPTICAL FIBRE CABLE CAPACITYAbout four times FY2022Japan ¥40 billion plus U.S. up to ¥260 billion. Ramping up in stages from 2030
NEXT-GENERATION PLANT AT SAKURAAbout ¥45 billionAbout twice the FY2022 capacity (table in the mid-term plan materials)

The 2028 Mid-term Business Plan positions Information and Communications as the business that will drive growth in "information storage" and "information infrastructure", and says the company will concentrate human and financial resources on it Sourced. Over the three years it plans to allocate ¥300 billion to growth investment, ¥100 billion to strategic investment and ¥130 billion to other investment. On the product side, the plan cites higher output of MT/MMC ferrules and MMC-terminated trunk cables, more capacity for connectivity components at the plants in Vietnam, Mexico and Poland, and WTC® production equipment at the Morocco plant (targeted to start in the first half of FY2026). The plan assumes exchange rates of ¥150 to the US dollar for FY2026 and ¥145 from FY2027.

What could not be confirmed

None of the following appears in the primary sources Not yet confirmed.

The plant location for the investment of up to ¥260 billion in the U.S.; sales by product for the Information and Communications segment (the split between cable, connectors, fusion splicers and installation; the mid-term plan materials give only growth-rate charts with no amount scale); shipment volumes and customers for polarisation-maintaining fibre for CPO; and the names of major customers (the Annual Securities Report states that no single customer accounts for 10% or more of consolidated sales). Figures such as "Fujikura's global share of optical fibre is X%" mostly rest on research-firm estimates, and this article does not use them.

8. What the company is aiming for in optical communications and photonics

This section goes beyond what the company says directly. It sets out inferences that can be drawn from primary sources, each with its basis.

What can be readPrimary evidence behind itCategory
It will remain an all-round supplier of optical wiring and connections, not of parts that emit or convert lightThe Annual Securities Report describes its strength as a total solution spanning optical fibre cable, fusion splicers, optical connectors, optical components and telecommunications engineering, and mentions no volume production plans for lasers or optical transceivers for communications (the company's fibre lasers are for materials processing)Inference
It is turning the whole company into an information and communications companyIn the FY2028 plan, Information and Communications accounts for 65.6% of sales and 90.5% of operating profit (percentages are our calculation). The plan states that human and financial resources will be concentrated on itInference
It is knowingly deepening its dependence on U.S. hyperscale data centresU.S. sales are 44.2% of the consolidated total. The framework agreement with the U.S. Department of Commerce and the plan to invest up to ¥260 billion in the U.S.Inference
It is entering CPO and photonic-electronic convergence through fibre-side componentsRising shipments of polarisation-maintaining fibre for CPO, and an R&D priority stated as contributing to the development of photonic-electronic convergence technologies such as CPO by applying PANDA fibre and image fibre technologyInference
For multi-fibre optical connectors it has chosen to grow the market by sharing a standard with other companiesOn the agreement with US Conec, the company writes that Corning and Sumitomo Electric Lightwave have each concluded similar agreements and that each company will work to spread and standardise the technologySourced
One inference, explained in full

In announcing the October 2025 Porter Prize, the company's release quotes the organisers' citation. It says that, taking the saturation of Japan's optical fibre market as its cue, the business completely withdrew from producing and selling optical cable of conventional structures (slotted-core and loose-tube), specialised in optical fibre cable using the intermittently bonded ribbon fibre it developed itself, and provides the full range of related products, including optical fibre, optical parts and components, fusion splicers and optical application products Sourced. Fujikura's strength, in other words, lies not in any single product but in combining cable design, splicers, components and installation to lower the customer's total cost. Our reading is that, rather than entering the race in fast-turnover high-speed parts such as optical transceivers, it is concentrating on wiring, whose volume is bound to rise with every new data centre Not yet confirmed.

9. Map of partnerships in optical communications and photonics

Fig. 2 Fujikura's partnerships in optical communications. Sources: the Annual Securities Report for the year to March 2026, the 2028 Mid-term Business Plan materials (19 May 2026) and official releases (4 March 2025, 27 March 2025 and 11 March 2026). US Conec is a joint venture of Corning, Fujikura and NTT Advanced Technology, and an equity-method affiliate of Fujikura. Corning and Sumitomo Electric Lightwave have each concluded agreements similar to the March 2026 agreement on PRIZM® TMT. The companies receiving the 13,824-fibre cable and the fibre for CPO are not named, so only an empty box is shown for them.

10. Technologies, products and services

Product or serviceWhat the primary sources sayArea of light
SWR® / WTC®Ribbons of single fibres bonded intermittently (SWR®), housed in thin high-density cable wrapped with binding tape (WTC®). Sold as volume products in versions including 13,824 fibres (outer diameter 40 mm or less), 4,000 fibres for Japan (outer diameter 23 mm) and 1,728 fibres for air-blown installationInside data centres, DCI, carrier networks
Multi-fibre optical connector componentsMT ferrules, ferrules for MMC connectors and MMC-terminated trunk cables. The PRIZM® TMT ferrule is an expanded-beam type with a lens moulded in one piece with the resin at its tip, cutting mating force by about 70%Inside data centres
Polarisation-maintaining fibrePANDA fibre. Shipments for CPO rose in FY2025. TitaniaBend PANDA PM Fiber supports bend radii of 5 mm or less and cuts bending loss by up to about 90% compared with earlier fibre (at the sample shipment stage)Inside optical transceivers and CPO
Fusion splicersSold for installation work and also to factories making optical equipment for data centres. The "100R" splices up to 16 fibres at once, with automatic alignment and end-gap correction (launched April 2026)Installation and manufacturing
Optical devicesOptical fibre couplers built into submarine cable repeaters, being developed as composite modules that integrate several partsSubmarine and long-haul
Next-generation optical fibre (research stage)Multi-core fibre and hollow-core fibre, aiming for thinner, lower-loss and lower-latency fibre. Multi-core fibre has been deployed in a working system with NICT and others (8K video, 300 m)Carrier networks, data centres
Telecommunications engineeringOptical cabling and connection work outside and inside data centres, mainly in the U.S. The mid-term plan materials describe this as the ability to provide "end-to-end" solutionsInside and outside data centres

A note on the performance figures. In the table above, the 13,824-, 4,000- and 1,728-fibre cables, the ferrules for MMC and the 100R are sold as volume products. TitaniaBend PANDA PM Fiber is at the sample shipment stage from FY2025 and is not a volume product. The multi-core fibre is an example of deployment in a working system (over a transmission distance of 300 m), not a product on general sale Sourced. "World first" and "world's highest" are both the company's own wording.

A materials engineer's view: bend-tolerant fibre is decided by "the surface of the glass"

Inside the housing of an optical transceiver or CPO, there is no choice but to fold the fibre back at a radius of a few millimetres. That raises two problems: one is light leaking out at the bend (bending loss), and the other is breakage starting from tiny flaws on the glass surface (mechanical reliability). For the second, Fujikura and Corning explain that TitaniaBend adds a titanium-doped layer to the glass surface Sourced. Placing a titania-doped silica layer on the outside is a known design that leaves compressive stress in the surface layer, which can be expected to counteract the stress that opens up flaws Not yet confirmed. For the first problem, bending loss, the company says it used a fibre design that operates in single mode over short lengths.

SWR® is also a materials story. A ribbon in which single fibres are bonded intermittently rather than along their whole length combines the advantage of a "ribbon", which can be mass-fusion spliced, with the advantage of "single fibres", which can be rolled up and packed into a thin cable. The spacing of the bond points and the softness of the bonding resin are likely what decide whether 13,824 fibres can fit within an outer diameter of 40 mm Not yet confirmed. The thinking behind thinner, denser optical fibre is easier to place alongside our explainer on optical interconnects and SerDes.

11. The risks this company carries

RiskSubstanceCategory
Swings in demandThe Annual Securities Report says that, because its products are for infrastructure, they are affected by trends in capital investment and changes in customers' purchasing policies, and that large short-term swings in demand could affect resultsSourced
Concentration on the U.S. marketSales to customers located in the U.S. are 44.2% of consolidated net sales. The subsidiary AFL alone accounts for about 30% of consolidated salesOur calculation
Recovering large investmentsThe investment of up to ¥300 billion in Japan and the U.S. is planned to ramp up in stages from 2030. Nobody can yet confirm whether data-centre investment will still be as strong by thenInference
Concentration of profitThe Information and Communications segment earns 80.9% of group operating profit, rising to about 90% in the FY2028 plan. Weakness in one segment hits the whole company directlyOur calculation
Exchange ratesThe mid-term plan assumes ¥150 to the US dollar (FY2026) and ¥145 (FY2027 onwards). A stronger yen would push down sales and profit in yen termsSourced
Policy and tradeThe Annual Securities Report cites U.S. tariff policy and geopolitical risk. The framework agreement with the U.S. Department of Commerce also depends on the policy continuingInference
Quality controlIn October 2025 the company published its final report on the improper quality control cases in group products it announced in 2018 and 2019 (152 cases, 99 customers). The cases were not limited to optical products, but any recurrence would go straight to customer trustSourced
