Like copper cables, attenuation and _____ considerations are of concern for optical fiber systems.

Attenuation in optical fiber systems refers to the reduction of signal strength as it travels through the fiber, which can be influenced by various factors. The correct answer, which highlights the significance of physical environment considerations, is particularly relevant in the context of optical fiber installations. The physical environment includes factors such as temperature fluctuations, moisture, and physical obstructions that can affect the performance and longevity of the fiber.

For instance, if optical fibers are installed in areas with high humidity or temperature extremes, there may be a risk of increased attenuation or even damage to the fiber itself. Additionally, the installation environment can dictate the type of fiber used and how it is deployed, such as whether to use indoor or outdoor rated fiber.

In contrast, while electrical interference could be a concern for copper cables, optical fiber is inherently immune to electromagnetic interference, making this consideration less critical for fiber systems. Cost is a factor in nearly all installations, but it does not directly relate to the technical performance of optical fibers like attenuation and environmental challenges do. Installation techniques are also important, but they focus more on the methods of deploying the fiber rather than the specific concerns involving attenuation and environmental factors.

Thus, understanding how the physical environment affects fiber performance is essential for ensuring reliable communication over
