Why does bending a fiber increase attenuation, and which practices help mitigate this?

Why does bending a fiber increase attenuation, and which practices help mitigate this?

• A. Bending increases attenuation by causing light loss; mitigations include using proper bend radii, bend-insensitive fibers, and careful routing.
• B. The light radiates into the cladding; mitigate with proper bend radii, bend-insensitive fibers, and careful routing.
• C. Attenuation is unaffected by bending.
• D. Only temperature changes affect bending attenuation.

Answer: (B)
