The working mode and benefits of a fibre network

  • Fibre network transmits data via light pulses in fibre-optic cables, offering efficient, high-speed network by converting light to electrical signals.
  • The installation of fibre network involves laying fibre-optic cables from a central hub, followed by setting up an optical network terminal and a compatible Wi-Fi router inside homes.

The fibre network offer high-speed network, low latency, and stable connections, supporting multiple devices simultaneously, making them ideal for modern digital needs.

Fibre network uses fibre-optic cables made of glass or plastic, transmitting data through light pulses. This ensures efficient data travel, converted into electrical signals for high-speed connections.

How fibre network works

Fibre network operates using fibre-optic cables, which are composed of thin optical fibres made from glass or plastic. These fibres consist of two main parts: the core and the cladding. The core is where the light travels, and the cladding surrounds the core to create an internal reflection, allowing the light to travel long distances without escaping. The transmission of data in fibre-optic cables occurs through light pulses, which hit the glass cladding at a shallow angle, creating a mirror-like reflection. This process, known as total internal reflection, ensures that the light, and therefore the data, travels efficiently. When these light pulses reach their destination, an optical network terminal converts them into electrical signals, facilitating a high-speed network connection.

Installation of fibre network

The installation of fibre network involves several steps, starting with the approval of a fibre rollout in a particular area. The initial phase includes installing a fibre ring, which serves as the main conduit for fibre distribution from a central hub. Following this, trenches are dug to lay the necessary fibre-optic cables, connecting homes and businesses to the central distribution network. Once the outdoor installation is complete, the final step involves choosing a service provider who will install an optical network terminal (ONT) and a fibre-compatible Wi-Fi router inside the premises.

Advantages of fibre network

Fibre network offers numerous advantages over traditional network connections. One of the most significant benefits is its high speed, which can reach up to 1 Gbps or more, enabling quick downloads, smooth streaming, and efficient online gaming. Fibre-optic cables are also less susceptible to electromagnetic interference, ensuring a more stable and reliable connection.

Future of fibre network

The future of fibre network looks promising as technology continues to advance. With the increasing demand for higher network speeds and more reliable connections, fibre-optic technology is set to become the standard for both residential and commercial network services. Innovations in fibre optics, such as bend-insensitive fibres and advancements in DWDM (Dense Wavelength Division Multiplexing), will further enhance the performance and scalability of fibre networks. As the network of things (IoT) expands and more devices become interconnected, the need for robust, high-speed network will only grow.
