Detailed Solution
Download Solution PDFThe correct answer is 4) Transparent plastic
Explanation:
Optical fiber cables are used to transmit light signals over long distances with minimal loss. The core material must allow light to pass through it with very low attenuation and high internal reflection.
Materials Used:
There are two main types of materials used for optical fibers:
-
Glass (Silica-based) – used for long-distance and high-performance applications
-
Transparent plastic (e.g., PMMA) – used for short-distance, low-cost applications like:
-
Consumer electronics
-
Medical instruments
-
Automotive sensors
-
The question asks about general use, so transparent plastic is the correct choice for typical, less demanding fiber optic applications.
Additional Information
| Option | Reason |
|---|---|
| 1) Copper | Used in electrical cables, not for light transmission |
| 2) Aluminium | Also used in electrical wiring, not optically transparent |
| 3) Steel | Used for structural strength in the cable's outer layers, not for light transmission |
| 4) Transparent plastic | Suitable for core/cladding in general-purpose optical fibers |
