Study Notes
Optical Fiber Components and Function
- Optical Fiber: Thin, transparent fiber made of glass or plastic used to transmit light signals over long distances.
- Core: The central part of the optical fiber where light travels. It has a higher refractive index than the cladding.
- Cladding: A layer surrounding the core that helps confine light within the core. It has a lower refractive index than the core.
- Protective Jacket: Outermost layer of the optical fiber that protects the core and cladding from damage. Often made of materials like polyvinyl chloride (PVC) or high-density polyethylene (HDPE).
Optical Fiber Properties
- Refractive Index (RI): A measure of how much light bends when passing through a material. The core's higher RI causes light to reflect internally within the core.
- Primary Material: Optical fibers are mainly made of silica (SiO2), a material that provides high transparency and low signal loss.
Optical Fiber Size
- Fiber Diameter: A typical single optical fiber is thinner than a strand of human hair.
