Differences Between ST, SC, FC, and LC Fiber Connectors 2025
A fiber optic connector is a mechanical device that allows two fibers to be joined precisely, enabling light to pass with minimal insertion loss and reflection.
FC connector
Higher grades of polish give less insertion loss and lower back-reflection. For applications requiring very low back-reflection, the fiber end-face is polished at an angle (the typical industry standard being 8°)
Fiber Connectors
FC/APC connectors use angled fiber endfaces to obtain a high return loss (even in the disconnected state), but normally at the cost of increased insertion loss.
