Fibre optic cable, often simply referred to as "fibre optics" or "optical fibre," is a technology that uses thin strands of glass or plastic to transmit data, including text, sound, and images, in the form of light pulses. Fibre optic cables are the foundation of high-speed internet connections, enabling seamless streaming, rapid downloads, and lag-free online experiences. In telecommunications, they provide the clear and uninterrupted connections we rely on for everything from phone calls to video conferencing.

Furthermore, fibre optic cables form the backbone of vast global communication networks, connecting continents and facilitating international communication. Their ability to transmit data over long distances with minimal signal loss makes them crucial for data centres, cloud computing, and the ever-expanding Internet of Things (IoT).

## **Types of Fibre Optic Cables**

Understanding the differences between the types is crucial for selecting the right cable from [RS NZ's](https://nz.rs-online.com/web/) extensive range for your needs.

### **Single-Mode Fibre (SMF)**

Single-mode fibre excels in long-distance, high-bandwidth applications. Its smaller core diameter allows it to transmit data using a single mode of light, minimising signal dispersion and ensuring optimal performance over vast distances. This makes SMF ideal for telecommunications networks, long-haul connections, and undersea cables.

### **Multi-Mode Fibre (MMF)**

Multi-mode fibre is typically used for shorter distances, such as within buildings or local area networks (LANs). Its larger core diameter allows multiple modes of light to travel simultaneously, making it suitable for data centres and enterprise networks. While MMF is generally less expensive than SMF, its shorter transmission range makes it less suitable for long-haul applications.

## **Key Characteristics and Benefits of Fiber Cable**

Fibre optic cable offers a range of advantages over traditional copper cable, making it the preferred choice for many modern applications.

- **Speed and Bandwidth:** Fibre optic cables can transmit data at extremely high speeds, making them ideal for high-bandwidth applications such as the Internet, video streaming, and telecommunication. They can transmit data over long distances without significant signal degradation.
- **Low Latency:** Fibre optics have very low latency, which is crucial for applications that require real-time data transmission, such as online gaming and video conferencing.
- **Immunity to Electromagnetic Interference:** Unlike traditional copper cables, fibre optics are not susceptible to electromagnetic interference (EMI) or radio frequency interference (RFI). This makes them more reliable in environments where there is a lot of electrical noise.
- **Security:** Fibre optic cables are difficult to tap into because they do not radiate electromagnetic signals. This makes them a more secure option for transmitting sensitive data.
- **Long Distances:** Fibre optic cables can transmit data over very long distances without the need for signal repeaters, which are often required for copper cables. This is particularly advantageous for undersea cables and long-distance communication networks.
- **Lightweight and Space-Efficient:** Fibre optic cables are smaller and lighter than traditional copper cables, making them easier to install and manage. They are also less bulky and do not suffer from issues like crosstalk or signal degradation over distance.
- **Durability:** Fibre optic cables are highly durable and can withstand harsh environmental conditions. They are not susceptible to rust or corrosion.
- **Multiple Applications:** Fibre optic technology is used in a variety of applications, including internet connections, telephone networks, cable television, data centres, medical equipment, and military communications.

## **Applications of Fibre Optic Cables**

The versatility of fibre optic cables makes them suitable for a wide range of applications across various industries. Here are just a few examples of how RS NZ’s fibre optic cables are being used to improve communication and connectivity:

- **Internet Connectivity:** Fibre optic cables are the driving force behind high-speed internet access, delivering the bandwidth needed for seamless streaming, fast downloads, and lag-free online gaming. It’s rapidly becoming the standard for both residential and business connections, providing a superior online experience.
- **Telecommunications:** Fibre optic cables form the core of modern telecommunications networks, enabling crystal-clear voice calls, reliable video conferencing, and efficient data transfer. Their low latency and high bandwidth are essential for real-time communication.
- **Data Centres:** Data centres rely heavily on fibre optic cables to manage the immense amount of data they process and store. Fibre cables provide the speed and reliability needed for server connections, data backups, and cloud computing.
- **Medical Equipment:** Fibre optic cables are used in a variety of medical equipment, including endoscopes and lasers. Their ability to transmit light allows for minimally invasive procedures and precise medical imaging. Fibre optic light cable also plays a crucial role in high-speed data transfer within hospitals and medical facilities.
- **Military Communications:** The security and reliability of fibre optic cables make them ideal for military communication systems. They are used for secure data transmission, surveillance, and command and control operations.
