Takeaways

• 😀 Fiber optic technology uses light for transmission, unlike copper cables, which use electromagnetic waves.
• 😀 The core of fiber optic cables is extremely thin, even thinner than a human hair, and is made of glass fibers.
• 😀 Fiber optic cables are made up of several layers, including the outer jacket, cladding, coating, and the core.
• 😀 Fiber optic cables can be large in diameter, with some containing up to 12 cores or more for heavy data transmission.
• 😀 Dropcore fiber optic cables typically contain only 1 or 2 cores, while cables with larger diameters have more cores (e.g., 12+).
• 😀 The color coding system in fiber optic cables uses 12 different colors to identify the fibers, and can be memorized with mnemonics like 'bocap meikut'.
• 😀 Fiber optic cables are measured using a power meter with decibels (dB), in contrast to copper cables, which are measured with a voltmeter.
• 😀 The historical development of fiber optics started with Alexander Graham Bell's invention of the optical telephone in 1880.
• 😀 In 1951, fiber optic technology was first used in the medical field for non-invasive internal examinations.
• 😀 Fiber optics are now used in various modern communication systems, providing high-speed internet, TV, and phone services.
• 😀 The concept of Passive Optical Networks (PON) and Optical Network Termination (ONT) is used to distribute internet and other services via fiber optics.

Q & A

What is the main difference between fiber optic cables and copper cables?

Fiber optic cables use light as the medium for transmission, while copper cables use electromagnetic waves. Additionally, fiber optic cables are made from glass fibers, whereas copper cables are made of copper.

What are the main components of a fiber optic cable?

A fiber optic cable consists of several components: the core (made of glass fiber), coating, strength member, and outer protective layers such as jackets.

What is the function of the 'core' in a fiber optic cable?

The core is the central part of the fiber optic cable and is made of glass. It is responsible for transmitting light signals over long distances.

How are fiber optic cables measured in terms of signal strength?

Signal strength in fiber optic cables is measured in decibels (dB) using a power meter, which is different from copper cables that are measured using a voltmeter.

What is the significance of the 12-color code used in fiber optic cables?

The 12-color code is used to identify individual fibers within a cable. It ensures that fibers are correctly connected and helps in managing the cable system efficiently.

How can you easily memorize the 12-color code used in fiber optics?

You can use a mnemonic to remember the 12-color code, such as 'BOCAP MEIKUPIT,' where each letter represents a color in the sequence: Blue, Orange, Green, Brown, Gray, White, Red, Black, Yellow, Purple, Pink, and Turquoise.

What is the historical significance of fiber optic technology?

Fiber optic technology was first experimented with by Alexander Graham Bell in the 1880s with the invention of the 'photo-phone.' It was later used in medicine in 1951 and has since revolutionized communications, especially for high-speed internet.

What are the practical applications of fiber optic cables today?

Fiber optic cables are widely used for high-speed internet connections, video transmission, and telecommunications. They are also essential in modern systems like Optical Network Termination (ONT) for providing internet, TV, and phone services.

What is the difference between a 'drop-core' fiber optic cable and larger diameter cables?

A drop-core fiber optic cable typically contains one or two cores and is used for direct connections, while larger diameter cables can contain more than 12 cores and are often used for distribution and backbone connections.

Why is it important to understand the fiber optic cable's color code when connecting fibers?

Understanding the color code is crucial because it ensures that fibers are connected properly. If two fibers of the same color but from different cables are connected, it will result in a failed connection and communication error.
