HFCL is a technology company that designs and makes the physical and electronic kit the internet runs on - optical fibre, cables, radios, routers, and defence electronics - all from its own factories in India. It started in 1987 as a small telecom manufacturer and has spent three decades climbing the value chain, deliberately pivoting from a government-heavy project contractor into a product-led, export-heavy business that now sells to global hyperscalers and Tier‑1 telecom operators. The recurring approach is vertical integration: it makes the raw material, the fibre, the cable, the connectivity boxes, and the active electronics, then deploys them in its own turnkey networks - cutting out middlemen and keeping IP in-house at every step.
Business segments
Four engines at different stages - a fibre-and-cable cash cow feeding global data-centre demand, a telecom-equipment challenger scaling on India’s 5G build-out, a defence-electronics bet under construction, and a legacy project-execution arm that now serves as a captive deployment channel for the company’s own products.
1. Optical fibre and cable: the physical backbone of the internet
HFCL is India’s largest optical fibre cable supplier, and a structural global supply shortage - driven by AI data centres - has turned its integrated fibre-to-cable manufacturing base into a multi-year export machine.
- It makes the glass, not just the cable - HFCL draws its own optical fibre at its Hyderabad plant, with optical fibre capacity doubled to 28 million fibre kilometres (mn fkm) per year and optical fibre cable capacity of 34 mn fkm p.a., so it is not dependent on third-party fibre suppliers when global supply tightens.
- A hyperscaler contract that locks in capacity - a single five-year global supply deal with a hyperscaler, worth roughly USD 1.1 billion, secures more than half of the company’s cable output over the medium term and is described as probably the largest single contract ever won by an Indian telecom company.
- The EU anti-dumping exemption is a moat - the European Commission identified HFCL as the only Indian company not dumping optical fibre cable in Europe, so it is the sole Indian manufacturer exempted from anti-dumping duties and can serve European customers directly from its Indian plants.
- Backward integration into preform - a preform manufacturing facility (preform is the basic raw material for optical fibre) is being built through a subsidiary with planned capacity of roughly 300-310 metric tonnes per year, aiming to secure supply and widen margins by July 2029.
2. Telecom and networking equipment: the active electronics layer
A portfolio of indigenously designed Wi‑Fi access points, 5G radios, and IP/MPLS routers that turns HFCL into a homegrown alternative to global networking vendors for Indian telecom operators and enterprises.
- India’s largest supplier of unlicensed band radios - HFCL claims to be the largest supplier of point-to-point unlicensed band radios in India and counts itself among the leading suppliers globally, with an installed base of over five lakh units.
- First-mover in Indian 5G equipment - it launched India’s first indigenously developed 5G Fixed Wireless Access customer premises equipment, shipped over four lakh units in the launch year, and secured repeat orders worth roughly ₹800 crore.
- Routers deployed in the national broadband network - its indigenously developed IP/MPLS routers, ranging from 56 Gbps to 800 Gbps, won orders worth more than ₹800 crore under BharatNet Phase III and are deployed in BSNL’s nationwide network expansion.
- R&D with global chip partnerships - three R&D centres with 229 engineers work alongside Qualcomm, Broadcom, Intel, and others to build products, and the company launched the world’s first open-source Wi‑Fi 7 access points.
- Government production incentives underpin scale - HFCL is approved for up to ₹652.79 crore in production-linked incentives over five years, tied to a committed investment of roughly ₹425 crore in a dedicated telecom-equipment manufacturing facility near Gurugram.
3. Defence equipment: a homegrown arsenal under construction
A defence-electronics business built on own-IPR fuzes, thermal sights, and surveillance radars, now being consolidated into a dedicated subsidiary with a large export-oriented aerospace order book.
- Owns the IP on every key product - electronic fuzes for artillery, thermal imaging cores, thermal weapon sights, and multi-mode hand grenades are all developed with HFCL’s own intellectual property, and the electronic fuze is NATO certified.
- A new factory already producing - a defence manufacturing facility in Hosur, Tamil Nadu, inaugurated in December 2024.
- A much larger campus being built - the Government of Andhra Pradesh has allocated 1,000 acres in Sri Sathya Sai District for a defence manufacturing complex that will house artillery shell production, TNT filling, and multi-mode hand grenade lines, with Phase I of 329 acres already allotted.
- Strategic partnerships with defence primes - a partnership with General Atomics Aeronautical Systems covers critical radar sub-systems for UAVs, and a partnership with Bharat Electronics Limited spans indigenous development across defence, telecom, and railways.
4. EPC and system integration: the captive deployment arm
A turnkey network-building business that has been deliberately shrunk as a share of revenue but remains the channel through which HFCL’s own fibre, cables, and equipment get deployed into large government and defence networks.
- Over two lakh kilometres of fibre laid - HFCL has laid more than 2,00,000 kilometres of optical fibre cable for telecom operators, and connected roughly 3.5 million homes with fibre-to-the-home for Reliance Jio across 207 cities in Northern India.
- The armed forces’ dedicated network builder - it built a standalone optical MPLS-based network for the Indian armed forces under a contract valued at ₹8,098 crore, and provides surveillance and security systems at over 300 army locations.
- Railway and metro communications specialist - HFCL has deployed telecom networks for seven greenfield freight corridors, implemented video surveillance at roughly 750 railway stations, and executed metro network projects from Mauritius and Dhaka to Delhi and Surat.
- Deliberately de-emphasised in favour of products - projects contributed 73% of revenue in FY21 but roughly 38% by FY26, as the company resolved to avoid low-margin turnkey work and shift toward higher-margin product sales.
Group structure and partners
A parent company with a listed subsidiary, a newly formed defence-and-aerospace platform, and a web of international sales entities, underpinned by technology partnerships with global semiconductor and defence primes.
- HTL Ltd is the listed operating subsidiary - HFCL holds 74%, the Government of India holds 26%, and HTL manufactures optical fibre cables, passive connectivity products, and key raw materials while also executing defence wire-harness orders for fighter jet upgrades and T‑72 tank modernisation.
- HFCL Advance Systems is the defence consolidation vehicle - post a ₹175 crore investment round, HFCL holds 51.02%, with the remainder held by Mr. Anant Nahata, Mr. Sushant Mohan Gupta, Mrs. Shubhra Gupta, BAS Engineering Private Limited, and ITI Holdings and Investment Private Limited; the subsidiary will house the aerostructure acquisition, the Raddef radar business, and the thermal weapon sight business.
- International subsidiaries provide local market access - wholly owned entities in the Netherlands, USA, Canada, UK, and Australia serve as sales and holding vehicles, though most were yet to commence operations as of their incorporation dates.
- Technology partners include the global chip and defence ecosystem - Qualcomm, Broadcom, Intel, NXP, TI, and Mediatek for telecom products; Microsoft for private 5G; General Atomics for UAV radar; and DRDO for technology transfers on communication systems and hand grenades.
