Professional Q&A
Q1: What is the benefit of APC polish in an FC connector?
A1: APC stands for Angled Physical Contact, where the ferrule endface is polished at an angle (typically ~8°). This reduces back-reflection significantly, delivering high return loss (> 60 dB) and improving signal quality in single-mode systems.
Q2: Why use a non-adjustable 0.9 mm connector instead of an adjustable one?
A2: Non-adjustable connectors, like this 0.9 mm version, are pre-optimized at the factory for consistent dimensional accuracy and optical performance. They simplify installation, reduce field tuning time, and are ideal for mass-produced fiber assemblies.
Q3: Can this connector be used in demanding vibration environments?
A3: Yes. The threaded metal coupling and rigid construction help maintain stable connections even in environments with mechanical vibration and movement.
