SM FC/APC/UPC Fiber Optic Terminator

The SM FC/APC/UPC Fiber Optic Terminator is designed for single-mode fiber optic systems, commonly used in high-precision testing, protection, and experimental applications. It features the FC connector, known for its stable threaded connection and strong vibration resistance, making it ideal for high-reliability environments like communication devices and fiber optic sensing systems. The terminator supports both APC (Angled Physical Contact) and UPC (Ultra Physical Contact) end-face designs. The APC connector has an 8° angled end-face that effectively reduces return loss, making it perfect for high-performance long-distance communications, while the UPC connector has a flat end-face, offering low insertion loss but higher return loss, suitable for general high-precision applications.

This terminator helps protect fiber optic interfaces from contamination, ensuring stable and clean connections. It’s widely used in fiber optic testing, communications, and protection systems, providing low insertion loss, excellent return loss control, and reliable performance in single-mode fiber optic networks.
