Weaving the Future: India set for a fibre optic revolution

The backbone of any digital revolution is not written in ones and zeros – it is woven in glass. Thinner than a strand of human hair, yet capable of carrying the weight of a nation’s digital aspirations, fibre optic cables form the neural network of a connected civilisation. For India, a nation of 1.4 billion digital dreams, this glass thread has become the luminous backbone powering its digital future.

Despite its critical role, fibre deployment in India has not kept pace with demand, and this gap presents both a challenge and an enormous opportunity.

The Indian fibre story: A tale of two decades

Twenty years ago, fibre in India was like a luxury car – prestigious but rare. Fast-forward to today, the country has laid over 3.8 million km of fibre, enough to circle the Earth 95 times. Yet, this impressive number tells only half the story. When you consider that China, for example, has deployed nearly four times this amount, you realise India’s fibre journey is just beginning.

India’s unique challenge lies in its numbers. With roughly 17 per cent of the world’s population but only about 7 per cent of its fibre infrastructure, the gap is stark. The country’s cumulative fibre deployed-to-population ratio stands at 0.1x, compared to 1.2x in the US and 0.7x in China.

Why fibre, and why now?

A decade ago, India’s digital infrastructure was a patchwork of copper cables, limited broadband penetration and sluggish internet speeds. The advent of 4G in 2016, spearheaded by Reliance Jio, was a watershed moment. Overnight, data became affordable and accessible to millions, triggering an explosion in internet usage. From streaming videos to digital payments, Indians embraced the internet like never before. Indian users on average consumed 20.27 GB of data per capita per month in 2024, which used to be 0.27 GB just about a decade ago.

For instance, an Indian telecom player like Jio’s mobile data traffic peaked at approximately 50,000 PB (1 PB = 1,000 TB) by the third quarter of 2024, showing an annual growth rate of 24 per cent. In stark contrast, China Mobile reported a modest 2 per cent year-on-year growth, peaking at around 40,000 PB during the same period. This is a clear testament to the explosive growth in India’s digital consumer demand; however, it also exposed the limitations of the existing infrastructure.

Just as you do not build industries without power, you cannot build a digital economy without fibre. The real question is whether we are laying down this infrastructure fast enough to keep up with the explosion in data consumption and evolving tech demands.

Unlike traditional copper cables, fibre uses light to transmit data, offering unparalleled speed, reliability and capacity. It is the difference between a narrow village road and an eight-lane expressway. While developed markets like the US, South Korea and Japan have long embraced fibre, India’s journey has been slower but no less significant. Over the past few years, the country has made steady progress, with fibre networks expanding to urban centres and, increasingly, to rural areas.

With digitalisation transforming industries and daily life at an unprecedented pace, India is uniquely positioned to leverage fibre as a catalyst for growth. But to do so, it must first address the challenges that have hindered its progress.

Challenges: The knots in the fibre

The road to fibre proliferation in India is paved with good intentions but fraught with challenges. One of the biggest hurdles to fibre proliferation in India is the fragmented implementation of telecom policies across states and local municipalities. The Telecommunications Act of 2023 has introduced a more structured and uniform approach to right of way (RoW). The act’s progressive provisions, such as standardised fees, promotion of fair access and mandated timelines for permissions, mark a significant step forward. However, its execution at the grassroots level remains uneven. Differences in interpretation, procedural delays and varying fee structures across regions continue to pose operational hurdles, impacting the pace of fibre deployment. The complex interplay between central directives and local implementation presents operational considerations that merit attention.

Furthermore, a key aspect of fibre deployment is balancing the cost-effectiveness of securing RoW with the practical challenges of execution. This includes acquiring the necessary permits for digging and construction, following best practices for installation, such as laying fibre at appropriate depths to ensure durability, and ultimately enabling seamless last-mile connectivity. Establishing reliable links between endpoints, whether towers, buildings or residential clusters, and the core network is essential for a robust infrastructure.

The industry has observed that streamlined administrative processes, such as single-window clearance systems adopted by some states, can significantly optimise deployment timelines while maintaining regulatory compliance.

The 5G conundrum

The roll-out of 5G in India has been met with both excitement and scepticism. According to a report by Ericsson, 5G subscriptions are expected to reach around 970 million by the end of 2030, accounting for 74 per cent of mobile subscriptions.

While 5G promises blazing-fast speeds and low latency, its true potential can only be unlocked with a sturdy fibre backbone. The lack of clear use cases has led to a “wait-and-watch” approach among consumers and businesses alike. The enterprise use cases for 5G – often touted as its killer applications – are still finding their feet. Sure, the technology could revolutionise manufacturing with ultra-reliable low-latency communications, enable smart cities and transform healthcare; however, many of these applications can be adequately served by well-implemented Wi-Fi and/or 4G networks combined with edge computing.

That said, dismissing 5G as merely “faster 4G” would be short-sighted. The technology’s true potential lies not only in its speed alone but also in its ability to segment networks (network slicing), deliver consistent quality of service and support massive machine-type communications.

For India’s industrial corridors and upcoming smart cities, this could be the difference between digital evolution and revolution.

The future hinges on fibre

India stands at a pivotal moment where robust fibre infrastructure has become fundamental to its digital evolution. The convergence of several technological and market forces makes this particularly significant.

The rapid adoption of generative artificial intelligence (AI) applications in India has created unprecedented demands on network infrastructure, requiring the kind of consistent, low-latency connectivity that only fibre can deliver reliably at scale.

The content landscape is undergoing a remarkable transformation. The proliferation of regional over-the-top platforms, combined with India’s growing creator economy, is driving data consumption patterns that increasingly favour high-bandwidth, low-latency networks. Major hyperscalers are responding to this trend by expanding their content delivery networks deeper into the country’s territories, necessitating robust fibre connectivity to ensure quality service delivery.

India’s data centre ecosystem is experiencing significant expansion, with major technology players establishing their presence across multiple cities. This growth requires dense fibre connectivity, not just for primary connections but also for the crucial redundancy paths that ensure business continuity.

The fibre-to-the-home market represents another significant growth vector. Traditional telecom operators and digital infrastructure providers are actively expanding their fibre footprint to capture this growing market.

The next wave of growth will come from unexpected quarters. Smart cities are emerging as digital organisms, with fibre connecting countless internet of things sensors for real-time traffic management and environmental monitoring, while the industrial landscape is transforming through machine-to-machine communications orchestrating complex manufacturing processes. This digital revolution extends from immersive augmented reality/virtual reality experiences requiring split-second responsiveness to autonomous vehicles communicating with smart infrastructure, all demanding the reliability and low latency that only fibre networks can deliver.

The road ahead

From enabling AI and 5G to supporting data centres and content delivery, fibre is the lynchpin of India’s digital future. Realising this potential will require a concerted effort from all stakeholders – the government, industry and consumers alike.

The challenges are real, but so are the opportunities. If India can overcome the hurdles of policy fragmentation and roll-out challenges, it stands to reap a digital dividend that could transform the lives of millions. The road ahead is long and winding, but the destination is worth it.
