Professional Q&A
Q1: What does APC mean and why is it important?
A1: APC stands for Angled Physical Contact, a type of fiber endface polish where the ferrule endface is angled (typically 8°). This reduces back-reflection and improves return loss, which is critical for high-performance single-mode systems and high bandwidth networks.
Q2: Can FC APC connectors be used in outdoor fiber deployments?
A2: Yes. FC APC connectors with ruggedized metal coupling and wide temperature range are suitable for protected outdoor and industrial environments when properly housed and strain-relieved.
Q3: What’s the difference between FC/APC and FC/UPC?
A3: Both are FC connectors; APC has an angled polish that gives much higher return loss (typically ≥ 60 dB) than UPC (≤ 55 dB), making APC better for systems sensitive to reflection. They are not directly compatible.
