You may already know why there is so much talk about fiber optic cables and why they’re in super high demand all around the globe, right? Well, the one simple reason is that these cables help travel the data as pulses of light, which is super fast. And since India is a growing market where telecom connectivity is going on at full pace, that’s the very reason why we need more and more of these cables with every passing year. As per some reports, this market is about half a billion dollars as of 2025, but it is expected to grow as much as USD 1.0 billion by 2031. And this doubling of growth won’t happen on its own, there are a few plays that will cary it out, so, in that regard, let’s talk about the Top 10 Leading Fiber Optic Cable Companies In India 2025. Here we go.
1. HFCL (Himachal Futuristic Communications Ltd)
Well, there is little to no doubt that in 2025, we could not have added any other company in this niche than HFCL. Why? Actually, the reason is pretty simple, like, a little more than thirty years ago, what was just a small idea has now transformed into the most influential company in India’s optical fiber market. How and why? First of all, HFCL is the core of the large-scale projects such as BharatNet, and their role is not limited to merely assembling cables; rather, they are producing the most basic parts of the cables as well, which enables them to have absolute control over the standard and cost of the products right here in the country. Just like that, in the previous financial year, HFCL was able to generate a revenue of ₹4,743 crore and a profit of ₹317 crore, mostly by leveraging its strong relationships with telecom majors.
2. Sterlite Technologies Ltd
In this very domain, of course, Sterlite is very few (I mean very, very few) companies that have gone global and are now famous on a world stage for their fiber cables. Why and now? See, the main thing that differentiates Sterlite from other companies is its incessant concentration on advanced fiber technology, for example, super high-density cables, 5G compatible structures, and data center solutions. For these reasons exactly, their order book went beyond ₹7,000 crore, and in FY23, the top line grew by more than 26%, whereas the bottom line increased by 57% substantially.
3. Finolex Cables
And then comes Finolex, you know, a company started in 1958 that is doing super well decades later in 2025 as well. It’s a company that has not lost its charm because it is still very much in demand. One of the reasons could be that the company is now a one-stop shop (quite literally) for all the needs in the field of fiber optics, such as FTTH cable, aerial cable, and even armored cable.
4. Vindhya Telelinks
Coming at number four, well, Vindhya Telelinks is unique because they are not only cable manufacturers, but also enablers of telecom infrastructure. Sure enough, years later, the company has become a preferred brand for various government and private sector fiber projects that demand solutions for indoor, outdoor, and aerial installation. Their FY23 top line was close to a double of almost ₹2,900 crore, thus propelling them to become one of the most rapidly expanding entities in this very list.
5. Aksh Optifibre
It could very well be that you don’t know the fact that Aksh Optifibre is the biggest manufacturer in the world of FRP rods, you know, one of the main components in fiber cables. Aksh was established in 1994 and is able to maintain a lead by producing 70% of the cable cost components in-house; this way, they are able to keep their prices competitive and, at the same time, maintain the quality standard for exports.
6. Birla Cable
Birla Cable, initially known for its name that crosses various industries, has become a major fiber optics player with a strong experience in providing telecom-grade solutions. And sure enough, talking of their current standings, along with the prestigious Indian Railways, Birla Cable has increased its total revenue almost by two times from ₹223 crore in FY20 to more than ₹535 crore in FY23, while profits have been growing at a good pace as well.
7. Polycab India
Polycab is a company that is mostly recognized for its power cables. But surely, since we have added them to this list today, that means they’re doing their part in fiber optic cable seen as well, right? Yes, that is pretty much the case. Polycab’s fiber products have become the local favorite options of metro, FTTH, and village broadband setups by utilizing its huge dealer network of more than 4,000 partners and 150,000+ retail points.
8. RR Kabel
Rarely is it known that RR Kabel is exporting to over 80 countries, and that fact alone is enough to tell how globally their fiber products are respected. Their super focus on safety-first features, such as mailable, low-smoke, and environmentally friendly cable designs, makes them stand out, particularly for the application in such sectors as smart buildings and public infrastructure, and that’s why they’re growing super strong not just in India but in some foreign countries as well.
9. M-Core Industries
Surely, a relative newcomer, M-Core only started operations in 2019, but they have already made a name for themselves as a reliable supplier of FTTH, coaxial, and networking cables to the sectors of banking, electronics, and home ISPs. A little more about them, see, operating out of Delhi, M-Core is able to combine performance and cost efficiency in its product, and maintain international standards.
10. Relemac Technologies
At last but an interesting option, see, Relemac is the name that has been in the background of the scene quite consistently and quietly for quite a while and is still going, that’s 1993 when they started. One of the factors that makes Relemac still trendy is its adaptable range of products like, starting with the usual fiber cables and ending with the ones that are specially made for very specific applications.
Conclusion
In the fiber optic cable scene right here in India, these are by far the biggest and most preferred choices in the country, and sure enough, these are the players that are quite literally, as we speak, carrying out the growth. So, just keep an eye on them if you’re into who’s making it big in the fiber optical cable market of the country.
