What is Plastic Optical Fibre (POF)?
Plastic Optical Fibre (POF) is a type of optical fiber made from plastic materials instead of glass. It is primarily used for short-distance data transmission applications due to its lower bandwidth and higher attenuation compared to glass fibers.
Key Components of POF
- Core: Plastic Optical Fibre The central part of the fiber made from plastic material, through which light signals travel.
- Cladding: Plastic Optical Fibre A layer surrounding the core that reflects light back into the core, ensuring efficient transmission.
- Buffer:Plastic Optical Fibre A protective layer that shields the core and cladding from external factors like moisture, temperature fluctuations, and mechanical stress.
- Jacket: The outer layer that protects the entire cable from environmental elements and mechanical damage.
Advantages of POF
- Flexibility: POF is more flexible than glass fibers, making it easier to install and route in tight spaces.
- Cost-Effectiveness: Generally more affordable than glass fibers, especially for short-distance applications.
- Light Weight: POF cables are lighter than glass fiber cables, reducing installation and maintenance costs.
- Safety: POF is not prone to shattering like glass fibers, making it safer to handle.
