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.

Nigerian Communications Commission (NCC) has reaffirmed its commitment to promoting efficient broadband infrastructure deployment in Nigeria through collaborative implementation of the Dig Once Policy.

L-R: Prof. Olalekan Yinusa, Executive Director, Policy, Strategy and Research, Nigeria Governors’ Forum; Mr. Ayuba Shuaibu, Director, Policy Competition and Economic Analysis, Nigerian Communications Commission, NCC; Engr. Nadungu Gagare, Permanent Secretary, Federal Ministry of Communications, Innovation and Digital Economy; Dr. Helen Aderibigbe Adeniyi, Hon. Commissioner, Ministry of Innovation Science and Technology, Kogi State, during the 2nd Stakeholders ‘ Consultative Forum on the Study to Develop a Mechanism and Cost-Based Structure for Sharing Duct Built Under The Dig-Once Policy in Nigeria, on the 8th July 2026, at the NCC Annex Office Mbora Abuja.

The Commission gave the assurance at the Second Stakeholders’ Consultative Forum to Develop a Pricing Mechanism and Cost-Based Structure for Sharing Ducts Built Under the Dig Once Policy in Nigeria, held at the NCC Annex Office, Mbora, Abuja, on Wednesday.

The forum brought together representatives of federal and state government institutions, telecommunications operators, infrastructure companies, industry associations, development partners and other key stakeholders to deliberate on the interim findings of the study and provide input towards the development of a transparent, equitable and cost-based framework for sharing underground duct infrastructure.

Speaking at the event, NCC’s Director, Policy, Competition and Economic Analysis, Mr Ayuba Shuaibu, said the consultative engagement underscored the Commission’s commitment to an open, transparent and inclusive regulatory process that accommodates the interests of infrastructure providers, network operators, public institutions and consumers.

Shuaibu noted that the proposed framework is intended to encourage infrastructure sharing, improve asset utilisation, reduce the cost of broadband deployment and facilitate the expansion of telecommunications infrastructure across the country.

According to him, the study is designed to establish a fair and transparent pricing mechanism for sharing underground ducts deployed under Nigeria’s Dig Once Policy, which encourages the installation of telecommunications ducts during road construction and rehabilitation projects. He explained that this would enable future fibre deployments without repeated road excavations.

“The Commission remains committed to a transparent, inclusive and consultative process. Our objective is to arrive at a pricing structure that balances the interests of infrastructure providers, access seekers and, ultimately, consumers, while also encouraging continued investment in broadband infrastructure.

“We encourage frank, constructive and solution-oriented contributions that will strengthen the final outcomes of this study,” Shuaibu said.
He added that observations, recommendations and contributions received from stakeholders during the consultation would be reviewed and incorporated into the final study report to ensure that the resulting framework is practical, commercially sustainable and responsive to industry realities.

Delivering the keynote presentation, the consultant, Mr Olugbenga Olabiyi, Managing Director of Dimension Data Limited, observed that passive infrastructure, including ducts, conduits, manholes and related facilities, constitutes one of the most capital-intensive components of broadband network deployment globally.

He said infrastructure sharing had emerged as an effective strategy for reducing deployment costs, improving efficiency and accelerating broadband expansion.
Olabiyi stated that Nigeria’s adoption of the Dig Once Policy presents an important opportunity to strengthen coordinated infrastructure deployment, minimise avoidable road excavations, improve utilisation of existing infrastructure and support broader broadband access across the country.

He also emphasised the importance of developing a predictable, transparent and equitable access framework, noting that inconsistent pricing models and unclear access conditions could undermine investment incentives and limit the benefits of infrastructure sharing.

“For Nigeria, where broadband expansion remains a national priority under the National Broadband Plan, successful implementation of the Dig Once Policy could become one of the most impactful infrastructure reforms in our telecommunications history.

“However, infrastructure sharing succeeds only when access is governed by fairness, transparency, predictability and effective market oversight.
“Without an equitable access framework, owners of shared infrastructure may inadvertently or deliberately create barriers to entry through excessive pricing, restrictive commercial conditions or discriminatory access practices. Such outcomes would undermine the objectives of the Dig Once initiative and discourage investment rather than promote it.

“This is why the NCC’s initiative to develop a cost-based pricing framework deserves commendation. A transparent and objective pricing methodology will provide confidence to investors, infrastructure companies, mobile network operators, Internet Service Providers, fibre operators and all participants within the communications ecosystem,” he said.

Participants at the forum reviewed the interim findings and provided recommendations on the proposed pricing methodology, implementation considerations and cost elements. Discussions focused on ensuring that the policy supports efficient infrastructure deployment while balancing the interests of infrastructure providers, access seekers and consumers.

The stakeholder consultation builds on earlier engagements conducted by the Commission on the study. It also aligns with the NCC’s commitment to implementing regulatory initiatives that promote broadband expansion, encourage infrastructure sharing and advance Nigeria’s digital transformation agenda.
