Fiber Optics Technology: Emerging Facts You Need to Know

INTRODUCTION
Fiber Optics is an optical communications technology that allows for the transmission of data over long distances without any loss of information. This technology was originally developed to allow telephone communication over longer distances using a single ground wire and an optical fiber, which made it far more cost-effective than systems based on repeaters or multiple copper lines. Optical fiber cable allows the delivery of data, voice, video and any other type of signal to be sent through glass or plastic fibers. Optical cables are made out of flexible and light materials that protect the optical fibers inside from tension, bending, or crushing without impacting the ability of the fibers to transmit signals.

HOW OPTICAL FIBERS WORK?

Let’s now understand how signal transmission over optical fiber works. The process begins with a transmitter, which converts electrical signals into light signals. These light signals are launched into the core of the optical fiber, which is surrounded by a cladding layer. The core is typically made of glass or plastic and is designed to carry the light signal. The cladding layer is made of a different type of glass or plastic and serves two functions. First, the cladding is designed to reflect light back into the core, helping to maintain signal power. Second, the cladding provides physical protection for the core.

As the light travels through the core of the optical fiber, it bounces off the cladding layer at a shallow angle. The design of the core and cladding ensures the light undergoes total internal reflection, keeping the light within the core. The light signal can travel for very long distances with minimal attenuation (loss of signal strength) as long as the fiber is kept free from damage or attenuation-causing factors such as bending, contamination, or attenuation due to atmospheric conditions.

The signal is then received at the other end by a receiver, which converts the light signal back into an electrical signal. This signal can be sent over very long distances without significant loss of signal strength, and it is also less susceptible to interference than other types of communication cables. Fiber optical cable is widely used for long-distance communication, including internet connectivity, telephone lines, and cable television transmission, due to its high bandwidth and low attenuation characteristics.

Major Applications for Fiber Optic Cable:

The following is a brief look at some different applications for fiber optic cable:

Technology has revolutionized communications, and it continues to do so today. Fiber optics may be found in the world of modern-day manufacturing, but they can also be found within your home or office. If you're curious about fiber optic cable, keep reading!

TELECOMMUNICATION:

Fiber optics are one of the most versatile and consistent systems that have been developed to date. One of the main applications of fiber optics is broadband communications due to their high transmission capacity and low interference. This can be applied not only for long-distance links but also for local networks within a particular area, which allow faster transmission speed compared to copper-based systems. The use of fiber optics has also improved the reliability and security of telecommunications networks, as fiber optic cables are immune to electromagnetic interference and difficult to tap into without detection. Fiber optic cables can transmit data at high speeds thus, making them the preferred choice for high-speed internet, cable TV, and telephone services.

AEROSPACE AND DEFENCE:

Optical fiber has several uses in military and aerospace applications due to its unique properties of high bandwidth, low attenuation, and immunity to electromagnetic interference. The use of optical fibers in communication systems ensures high-speed and secure transmission, making it difficult for the enemy to intercept or jam the signal. Fiber optic sensors are used in aircraft engines, weapons systems, and other critical components to monitor their performance and detect any faults or malfunctions. Optical fibers in military and aerospace applications have revolutionized communication, sensing, and weapons systems, providing high-speed and reliable connectivity in harsh and challenging environments.

NETWORKING:

Fiber optics has become an essential part of modern networking infrastructure because it offers several advantages over traditional copper-based cables, including higher bandwidth, longer transmission distances, and improved reliability. This technology is commonly used for long-distance communication, such as transcontinental communication. Many internet service providers (ISPs) use fiber optics to deliver high-speed internet to homes and businesses. Fiber optic cables can transmit data at speeds of up to 800 Gbps , making it ideal for bandwidth-intensive applications like video streaming and online gaming. Fiber optics is also commonly used in data centers to connect servers, storage devices, and other networking equipment. This is because optical fiber cables are immune to electromagnetic interference, making them more reliable and secure than traditional copper-based cables

Where can you find the best quality optical fibers?
