How Fiber Optics Transmit And Receive Data?

As evident from its name, fiber optics broadband relies on optical fibers to transmit or receive signals in the form of light. Each optical fiber is a thin strand of glass or plastic as thin as a hair and contains the following two parts:

• Core: Usually made up of glass, this is the innermost part from where the light passes through.
• Cladding: It is wrapped around the core and is made up of glass or plastic.

Information, in the form of light, passes through the strategically placed glass pieces which create a phenomenon called Total Internal Reflection. Light hits the glass of the core at a shallow angle of less than 42 degrees and gets reflected back. The cladding, made up of a material with different optical density or refractive index, keeps the light from reflecting out of the optical fiber.

Light emitting techniques such as LED or high-speed LASER pulses are used inside the fiber to transmit light. The light pulses constitute encrypted binary data or bits/bytes of data which contains data in the form of zeros and ones. One pulse denotes 1 whereas no pulse denotes 0.

Once the light pulses reach the end of the fiber known as the last mile or last stretch of fiber, they are converted to an electrical signal using an optical network terminal. It is the last mile that connects us to the backbone of the internet or the chain of devices used to connect the globe through the web.

How Does Fiber Optic Internet Work?

Fiber optic internet operates using a sophisticated process where light is used to transmit and receive data through optical fiber cables. Here’s a detailed look at how this technology functions:

1. Transmission

Data is converted into light signals using a laser or LED. This data encoding involves modulating the light source—turning it on and off—to encode binary data, where the presence of light represents a ‘1’ and its absence a ‘0’. The encoded light is then sent through the fiber optic cables, beginning its journey to the destination.

2. Travel

As the light travels, it stays within the core of the fiber, which is made from glass or plastic and surrounded by a cladding layer. The core has a higher refractive index than the cladding, which keeps the light signals confined and allows them to travel long distances through the cable by reflecting them internally.

3. Reception

At the end of the fiber, a receiver converts the light signals back into electrical signals. These signals are then read by computers and other devices, completing the communication process.

The fundamental technology behind fiber optic internet allows it to transmit data over long distances without significant loss, making it more efficient than traditional copper cables, which can lose signal strength over distance and are susceptible to electromagnetic interference. This method of using light allows for faster data transmission speeds, enhances bandwidth capacity, and reduces latency. Consequently, fiber optic internet is an ideal choice for both residential and commercial settings.

Types Of Fiber Optics Connections

Fiber optics connections vary based on how closely the fiber reaches the end user’s location. There are 4 main types of fiber connections provided by internet service providers, each one denoted as “Fiber to the X”, where X denotes the destination of the fiber connection.

Each type has unique benefits and applications:

• FTTH/FTTP/FTTD (Fiber To The Home/Premises/Desk): This is the most direct form of fiber optic connection, where the fiber reaches the living premises or business directly. It offers the highest speed and quality of service by eliminating any copper or coaxial segments. This connectivity line consists of a grail of fiber connections and is the most expensive among its peers.
• FTTC (Fiber To The Curb/Cabinet): In this setup, fiber is extended to poles or boxes near homes or businesses, but the final connection to the building is made through coaxial or copper cables. Since its infrastructure costs less, this type of connection is quite affordable and preferred by most households.
• FTTN (Fiber To The Node): Fiber cables run to a node in the neighborhood, which could be several kilometers away from the user’s premises. The remaining connection from the node to individual homes or offices is completed using existing copper wiring.
• FTTB (Fiber To The Building): Similar to FTTH, fiber is delivered to the building using copper cables, but the individual units are connected through the building’s existing wiring infrastructure. Here the building can be a hotel, residential building, school, or a hospital.

Besides these, fiber optics can be categorized into single-mode and multimode fibers:

• Single-Mode Fibers – They have a small core size (about 8.5-10 microns in diameter) and transmit infrared laser light (wavelengths of 1310 or 1550 nanometers). They are designed for long-distance communication as they allow the light to travel straight down the fiber without much reflection.
• Multimode Fibers – Larger in core size (about 50-62.5 microns in diameter), these fibers are used for shorter distances as they allow light to bounce more within the core, leading to modal dispersion which can limit bandwidth over long distances.

These different types of fiber connections and cable modes determine the application and effectiveness of fiber optics in various scenarios, impacting everything from installation costs to operational efficiency and speed.
