Which consequence results when reflections inside an optical fiber exceed the fiber's numerical aperture constraint?

💡 Explanation

Increased signal attenuation occurs when the incident angle exceeds the critical angle because total internal reflection cannot occur; therefore, light escapes rather than being guided down the fiber, leading to loss of signal strength rather than signal improvement.
