Professional Q&A
Q1: Why choose a non-adjustable connector over an adjustable one?
A1: Non-adjustable connectors are factory-optimized with fixed dimensions that eliminate the need for field tuning, ensuring consistent optical performance, faster assembly, and easier quality control in high-volume production or standardized cable assemblies.
Q2: What is APC and why is it beneficial?
A2: APC stands for Angled Physical Contact. The ferrule endface is polished at an angle (usually 8°), significantly reducing back-reflection and enhancing return loss, which is critical for high-performance single-mode networks and sensitive optical links.
Q3: Are FC APC connectors with 2.0/3.0 mm boots compatible with standard telecom cables?
A3: Yes — FC APC connectors supporting 2.0 mm and 3.0 mm diameters are designed to match typical telecom and enterprise fiber cable jackets, offering secure mating and robust performance across a wide temperature range.
