Which factor can lead to power loss when using optical fibers?

The factor that can lead to power loss when using optical fibers is the compatibility of fiber materials with UV light. Optical fibers are designed to transmit light effectively, but if they are not made of materials that are compatible with UV wavelengths, they can suffer from attenuation or degradation. This can occur due to factors such as absorption of UV light by the fiber material, which leads to a loss of light intensity over distance.

When fibers are exposed to UV light for extended periods, the materials can deteriorate, resulting in increased scattering and loss of transmitted power. Proper selection of fiber materials, specifically those that are UV-stable, ensures that the optical fibers maintain their integrity and efficiency when facilitating the transmission of light, particularly in applications where UV light is used.

In contrast, while the type of laser, distance the light travels, and the presence of additional components can also affect signal strength and performance, they do not directly attribute to material compatibility issues like UV light does. Thus, focusing on the materials' ability to handle UV radiation ensures minimal power loss in optical fiber applications.
