Compared to fibre optic networks, 5G is still in its infancy. The technology is still in its early stages and is not yet suitable for long-distance connections. In the meantime, fibre optics continue to be the backbone of the 5G network.

Long-distance 5G, not a step forward:

Compared to fibre optics, 5G may seem like a gimmick. It indeed has the potential to deliver faster speeds than fibre optics, but it won’t have the same performance.

A fibre optic cable can transmit data up to 70 kilometres, whereas wireless signals decrease power over distance faster than fibre. A dense mesh of small cells is connected via fiber-fronthaul cable in a typical fibre optic network.

Unlike fibre optics, the speed of 5G is not limited by distance. It’s designed to deliver data five times faster than 4G. The same technology can connect billions of devices, which could dramatically change the way we live. But it’s not ready to roll out in every country yet.

The technology is also not very good at penetrating the most challenging terrain. For instance, high-band 5G can’t penetrate buildings or trees, and it’s not likely to work through double-glazed glass.

It’s a good thing there is a solution to this problem: fibre optic cable. While it may not deliver blazing speeds, it’s the fastest and most stable way to connect to the rest of the internet.

Midband 5G is more widely available than millimetre-wave:

Unlike millimetre-wave, mid-band 5G isn’t limited to cities. It’s a good option for densely populated metropolitan areas, where speeds are often faster than high-band millimetre waves.

The United States government is slowly freeing up mid-band spectrum for 5G, but wireless operators will likely have to use a combination of spectrum types to cover customers. For example, T-Mobile reportedly has plans to expand its mid band 5G network to 260 million people by the end of 2022. It’s not charging customers a fee to use its 5G network. However, Verizon has already spent $50 billion on 160 MHz spectrum nationwide and plans to add more.

While high-band mmWave spectrum is fast and capable, it doesn’t travel very far. It’s best used in high-density situations, such as on a city street corner. In contrast, mid band frequencies can travel a few miles.

Midband 5G is an excellent option for people who want ultra-fast download speeds. It’s also good for streaming, gaming, and video calls. It’s not meant to replace cable modems or fibre, though. Instead, it’s designed for users who are looking for fast, super-convenient wireless connections. It can reach speeds of up to 1.8Gbps.

Fibre optics remain the backbone of the 5G network:

Despite the rise of fixed wireless transmission, fibre optics remain the backbone of the 5G network. The proliferation of optical fibre will increase as 5G becomes more widespread. The demand for fibre will be driven by consumer demand and bolstered infrastructure.

Fibre optics offer a small footprint and high bandwidth. Optical fibre is the ideal fronthaul for connecting dense meshes of 5G small cells. Fibre has a low loss and attenuation and a fast response time. Fibre networks also offer immunity to electromagnetic interference.

Fibre networks are built in a variety of ways. They can be underground, aerial, or underwater. Generally, a fibre network includes an aerial fibre optic cable and an underground fibre optic cable.

Optical fibre is installed in data centres. In addition, fibre optics are embedded in submarine and terrestrial cables. They are also used for high-speed data transfers.

Fibre optics are also used in mobile networks. Marvell Technology Group chips are used in data centres and networking equipment. Marvell acquired Innovium in 2021.

Integrated 5G with fibre cable networks makes sense:

Using 5G in conjunction with existing fibre cable networks makes sense. Not only will it be faster, but it will also save energy. By 2030, information and communications technology will be responsible for a fifth of global energy consumption.

In addition, 5G will enable the integration of renewable energy sources. It will also allow microgrids to function when the primary grid fails. It will also reduce greenhouse gas emissions from vehicles. It will also be able to run multiple concurrent application layers. It is expected that 5G will be able to deliver a downlink speed of 20 Gbps.

Fibre optic cable has a theoretical speed of 1 Petabit per second. It has a provisioned signal range of 70 km. However, fibre optics may not be suitable in some topographies.

The low-band spectrum ranges from 600 million hertz to 900 MHz. Its longer waves allow it to travel farther. AT&T uses it in more dense “coverage” areas.
