What is Lightning-Resistant POF?

Polyolefin Fiber (POF), also known as plastic optical fiber (POF), is a type of optical fiber primarily made from polyethylene or related polymers. Unlike traditional glass-based optical fibers, POF offers unique advantages such as ease of installation and cost-effectiveness. However, its susceptibility to environmental factors like lightning strikes has been a concern in certain applications.

Lightning-resistant POF addresses this issue by incorporating advanced materials and manufacturing techniques that enhance its ability to withstand the extreme electrical and thermal stresses caused by lightning. This makes it an ideal solution for outdoor and exposed installations where lightning is a potential threat.

Technical Parameters of Lightning-Resistant POF

1. Cladding Diameter: Typically ranges from 625 µm to 1000 µm, providing flexibility in application depending on the specific requirements.
2. Core Diameter: Varies between 400 µm and 980 µm, affecting the fiber’s light-gathering capability.
3. Fiber Jacket Material: Made from high-quality polyolefin with UV and weather resistance to ensure long-term durability.
4. Lightning Withstand Voltage: Designed to handle voltages up to 100 kV without degradation.
5. Temperature Range: Operates effectively within a range of -40°C to +85°C, making it suitable for diverse climatic conditions.
6. Attenuation: Low attenuation characteristics ensure efficient data transmission over longer distances.
7. Flexibility: High flexibility allows easy installation in various configurations without compromising performance.
