Which of the following is a component of an optical fiber?

• A. Cleaver
• B. Cannula
• C. Hood
• D. Cladding

Answer: (D)

An optical fiber consists mainly of three components: the core, the cladding, and the protective coating. The cladding is particularly important because it is the layer surrounding the core that has a lower refractive index than the core itself. This design enables the total internal reflection of light within the core, allowing it to travel long distances while maintaining signal integrity. The cladding contributes to the overall performance of the optical fiber by protecting the core from external factors that could disrupt the light transmission, such as physical damage or environmental conditions. Its role in ensuring that light is kept within the core is crucial for the efficiency and effectiveness of optical communication systems. Other options, such as a cleaver, cannula, and hood, do not form part of the optical fiber structure, though they may be relevant in contexts related to the use or handling of fibers. For instance, a cleaver is used for cutting optical fibers in preparation for splicing, but it is not a component of the fiber itself. Understanding the specific roles of the cladding helps in grasping how optical fibers function and their applications in various technologies.
