Which of the following are common causes of signal loss in fiber optic cable connectors?

Signal loss in fiber optic cable connectors can occur due to several factors that impede the proper transmission of light signals. Each of the stated causes contributes to this loss.

Axial misalignment refers to the situation where the ends of the fiber optic cables are not perfectly aligned along the same axis. This misalignment can prevent a smooth transmission of light from one fiber to another, leading to signal degradation.

Angular misalignment occurs when the ends of the fibers are not perfectly aligned at the correct angle. Instead of the light being transmitted directly from one fiber to the other, it can be reflected away or dispersed, thereby reducing the intensity and clarity of the signal.

Excessive separation between fibers, where the fibers are not close enough to effectively couple their light signals, can also result in significant signal loss. When fibers are too far apart, a substantial portion of the light does not make it from one fiber to the other, contributing to overall attenuation in the connection.

All of these causes highlight the delicate nature of fiber optic connections and the precision required to maintain optimal signal integrity. When considering the potential for signal loss, it's important to acknowledge that any one of these issues—or a combination of them—can severely impact performance, making the correct answer encompass all these factors.
