In the near future, Nigeria, like every other country, will require the mass adoption of fifth-generation (5G) technology to get ahead. To achieve this, it will require supporting infrastructure.

Here, we explore why fiber optic cables are a crucial part of this infrastructure, one that Nigerian homes, districts, and cities should acquire.   

In recent times, there’s been much talk about 5G technology and the possibilities that it could afford its users. The world anticipates the coming revolution that it will bring: ultra-fast connectivity, a much greater number of connected devices, and support for the Internet of Things (IoT).

Coincidentally, concrete moves towards testing and rolling out 5G across the world have come at the same time with a global spike in the demand for data-hungry services. This event, involving the increased use of video-streaming and video teleconferencing applications, has been driven by the COVID-19 pandemic and the restrictions on physical meetings that have come in its wake.

Nigeria has shown much enthusiasm about 5G. In 2019, it became the first country in Africa to initiate 5G network trials. And in May 2021, its upper legislative house approved the deployment of the technology nationwide.

However, a crucial question remains: do Nigeria’s homes, businesses, districts, and cities possess the infrastructure required for them to make the most of the technology?

5G Network Infrastructure: The Existing Gaps

5G infrastructure consists of a network of large and small cell base stations that possess the edge-computing capabilities needed to make 5G cellular networks functional.

The main infrastructure includes 5G small cell infrastructure and Radio Access Network (RAN) towers. Multiple-input, multiple-output (MIMO) antennas also have to be deployed in large numbers; fiber optic cables play a role as well.

How the Infrastructure Work as a Whole: The service area of 5G networks is divided into cells. Devices in each cell communicate through radio waves with local antennas, transmitters, and receivers. The antennas are connected to transmission electronics, which are in turn connected to switching centers in the telephone network by optical fiber.

Due to the costs involved in building new infrastructure from scratch, 5G is often made to utilize existing structures that have served older generation networks. However, some components may have to be upgraded or replaced for the technology to function as it’s designed to.

One of these components is cabling. In the past, 2G and 3G had relied on copper coaxial cables for carrying telecommunication signals over their networks. The bandwidth demands of 4G meant that they became less desired as a cabling option. They will be unable to support the even higher demands of 5G.

Why Fibre Optic Will Be Important for the 5G Revolution

As has already been hinted at, the major drawback for coaxial cables is the limited speeds that they can support. Until fairly recently, they were adequate for the 3G-dominant telecommunications landscape. But they have since fallen out of favour in quarters seeking faster speeds.

Coaxial cables can achieve speeds of between 10Mbps (Megabytes per second) and 1Gps (Gigabyte per second) and have recorded upload speeds of between 3Mbps and 50Mbps. Optical fiber, on the other hand, can attain speeds exceeding 10Gbps.

A major factor contributing to these differences in speed is the type of transmission carried out by coaxial and fiber optic. While optical fiber transmits signals as light, coaxial moves them in the form of electrical signals. The medium through which they are transmitted plays a role too. Optical fiber is made of glass and plastic; coaxial is primarily made of copper.

When compared to the telephone network generations they are supposed to support, it becomes clear why fiber optic cables are the preferred option for 5G. For instance, 3G devices can connect to the internet at a maximum speed of 21Mbps; 5G speeds can reach 1Gbps.

5G, Fibre Optic, and Last Mile Solutions

Earlier in this article, we referred to the benefits of 5G that homes, districts, and whole regions could access in the near future. Smart buildings, communities, and cities will become a reality, and high-speed connectivity will enable the integration of various economic sectors and drive innovative business models.

As has already been emphasized, the older copper-based transmission lines will not be able to keep up with the data demands of this new reality. Homes already utilizing this older technology may have to upgrade to fiber-optic cables if they are going to enjoy the comforts that 5G will bring.

The smart home will need much faster speeds to make its data-hungry, data-churning environment function optimally. Fiber optic cables could be one of the pillars on which a domestic, fully operational Internet-of-Things (IoT) will rest.

A key strength of fiber optic is that it’s built to last decades, and accommodates an ever-growing demand for data. Even if the much anticipated 5G revolution is slower in coming than expected, current users of fiber optic will find it easier to plug into that revolution when it happens than those without it.

Already, there’s been some movement in the direction of setting up high-speed fiber-optic infrastructure on a city-wide level. In 2020, the government of Lagos began installing fiber optic cables across the city. So far, over 3,000km of fiber optic cables have been deployed, according to the government’s own reports.

As 5G gains traction, it is expected that the provision of fiber optic cables at the level of individual homes will gather pace.

A Fiber to the Home Solution That Works

The advantages of fiber optic are not beyond the reach of Nigerian homes. Like their counterparts elsewhere in the world, they can acquire a Fibre to the Home (FTTH) solution that’s tailored for them.

Karl Toriola, chief executive, MTN Nigeria has defended recent tariff hikes by mobile network operators, stating they are essential for the “survival” of the telecoms industry in Nigeria, despite significant criticism.

The Nigerian Communications Commission (NCC) granted mobile network operators permission to raise tariffs by up to 50% last month, a change reportedly implemented on 11 February.

The increase has sparked public outrage, as mobile connectivity has become a vital necessity in daily life across the West African nation.

In an interview with Developing Telecoms, Toriola pushed back against criticism that the price surge was excessive, arguing that tariffs should have increased by approximately 300% to reflect the naira’s sharp devaluation and the country’s soaring inflation.

Addressing the impact of currency devaluation, Toriola emphasised that MTN purchases network equipment and software in US dollars, a process that has become significantly more expensive. With the naira’s decline, operators are now receiving three times fewer dollars than they did in 2023, making operations more challenging.

In February 2023, businesses could exchange 460 naira for one US dollar, but the currency has since devalued sharply. At the time of writing, a single dollar was worth 1,510 naira.

As Nigeria grapples with the sharp devaluation, MTN has been severely affected.

The company was technically bankrupt in 2023 as its liabilities surpassed its assets—a deeply concerning issue for the wider MTN Group, as Nigeria remains one of its highest revenue-generating markets.

“Because of these factors, we’ve seen our costs rise dramatically. The cost of leasing tower space and supplying energy to cell sites increased by 120% in the first three quarters of 2024. So, in comparison, a 50% tariff increase is not that high,” said Toriola.

National Information Technology Development Agency (NITDA) has reaffirmed its dedication to fostering an innovative ecosystem that balances regulation with industry growth. The agency is investing in cloud infrastructure, data classification, and AI applications to establish Nigeria as a leading digital hub in Africa.

Kashifu Inuwa, NITDA’s Director General, emphasized this commitment while speaking at the Africa Hyperscalers Digital Infrastructure Outlook 2025. The event gathered industry experts to explore Africa’s role in the expanding global AI-driven infrastructure boom.

In his remarks, Inuwa highlighted NITDA’s dual regulatory framework: rule-based regulation, involving strict compliance guidelines, and non-rule-based regulation, which allows for industry-led innovation with established benchmarks.

“Before we regulate anything, we need to be aware of the landscape, we need to be intelligent, we need to have data and make sense out of that data, we need to be dynamic because technology is fast-changing and we need to develop that agility within the regulatory framework,” Inuwa stated.

He also discussed the Cloud First Policy, introduced in 2019 to discourage excessive reliance on physical data centres. This policy encourages government agencies and private businesses to leverage cloud computing and digital solutions. Initially, businesses were granted waivers to use public cloud infrastructure, but NITDA is now pushing for local data centres to enhance their capabilities.

A major milestone for NITDA was its successful engagement with global hyperscaler providers, including Google Cloud, which pledged to collaborate with local data centres to drive cloud adoption and establish a hyperscaler data centre in Nigeria. This follows a meeting between Google CEO Sundar Pichai and President Bola Ahmed Tinubu in Paris, where the President shared his transformative ambition for Nigeria.

To further drive cloud adoption, NITDA is finalizing a framework that will mandate data classification, ensuring that certain data categories remain within Nigeria. This move is expected to attract more cloud service providers and bolster the country’s digital sovereignty.

Emphasizing the importance of AI applications, Inuwa disclosed that NITDA is prioritizing AI to enhance governance, regulation, and service delivery. He asserted that AI can revolutionize governance and business operations by automating processes, enhancing regulatory efficiency, and developing knowledge management systems.

Dr. Nadu Denloye, Co-founder of Telnet Nigeria Limited, also spoke at the event, highlighting Africa’s remarkable digital transformation driven by connectivity advancements, cloud adoption, data centres, AI, and a growing digital-native population.
