Which of the following statements is true regarding fiber optic connectors?

The statement regarding fiber optic connectors that is true is that connectors must be properly aligned to reduce insertion loss. Proper alignment is crucial when connecting fiber optics because misalignment can cause light to not couple efficiently from one fiber to another. Insertion loss occurs due to the bending, reflection, or scattering of light, and it is significantly impacted by how well the connector ends are aligned. High-quality connectors are designed to ensure optimal alignment, which minimizes loss and maximizes performance.

In contrast, the other statements highlight misconceptions about fiber optic connectivity. Not all connectors provide the same level of performance; different connector types are designed for various applications and environments, which can lead to varying levels of loss and reliability. Additionally, not every connector type is suitable for high-frequency applications; some connectors may not maintain signal integrity at higher frequencies due to design limitations. Lastly, connector selection does greatly impact signal integrity; the choice of connector can influence overall system performance, including how much signal degradation occurs during transmission.
