Which of the following statements about the loss of fiber connection points is correct?

Fiber Connection Loss Overview :

Fiber connection points introduce optical loss due to imperfections in alignment, reflections, or contamination.

Loss Comparison :

Movable Connector : Highest loss due to potential misalignment, contamination, and reflections.

Cord End Connector : Moderate loss, as these connectors are typically factory-polished and more stable than movable connectors.

Splicing : Lowest loss, as fusion splicing provides near-perfect alignment and minimal reflection.

Why C?

The order of losses from highest to lowest is: Movable connector > Cord end connector > Splicing .

Thus, the correct answer is C .
