Which set lists four desirable factors to look for in a connector?

• A. Low loss, mechanical protection, low reflectance, repeatability
• B. Low cost, quick installation, lightweight, decorative
• C. High insertion loss, brittle body, high reflectance, poor repeatability
• D. Large size, heavy weight, complex tooling, non-reusable

Answer: (A)

Desirable factors in a connector focus on preserving signal quality and ensuring reliable, repeatable performance. Low insertion loss means as little light power as possible is lost when the fiber is connected, which keeps the transmitted signal strong. Mechanical protection is important so the fiber and the alignment stay safe in real-world use, resisting handling and environmental stresses. Low reflectance, or low back reflection, reduces unwanted signals that bounce back toward the source, which can cause noise and instability in the system. Repeatability ensures that each connection behaves similarly, so a deployable network maintains consistent performance across many ports and over time. The other options describe traits that either don’t improve performance or actively hinder it: prioritizing cost or quick installation over optical quality can lead to higher losses or instability; a combination of high insertion loss, brittle construction, high reflectance, and poor repeatability is precisely what you want to avoid because it degrades signal, damages easily, and fails to provide consistent results. Large size, heavy weight, complex tooling, and non-reusability likewise hinder practicality and reliability in real deployments.
