FC-FC adapter: A passive device designed for FC-type optical fiber connectors. It connects two FC connectors through a precise thread locking mechanism to achieve stable docking of single-mode and multimode optical fibers. It has low loss and high durability, and is suitable for long-distance and high-reliability communication scenarios.
The FC-FC fiber optic adapter is designed to precisely align two FC connectors, enabling reliable fiber-to-fiber connections for single mode and multimode optical fiber systems. It is widely used in telecom networks, test equipment, and industrial fiber applications.
This FC-FC connector adapter provides stable mechanical alignment and low insertion loss performance. Available in UPC and APC polishing types, it supports high-precision optical signal transmission in demanding environments.

Our FC-FC optical adapter is manufactured with precise ceramic alignment sleeves to ensure consistent optical performance. Each adapter is tested for insertion loss and mechanical reliability, making it suitable for long-term deployment in professional fiber optic systems.
An FC-FC fiber optic adapter is used to connect two FC connectors, allowing accurate fiber alignment and stable optical signal transmission.
Yes, the adapter is available for both single mode and multimode fiber applications. Please confirm the required fiber type when selecting the model.
UPC adapters feature a flat polished end face, while APC adapters use an angled polish to reduce back reflection. The correct type should match the connected FC connectors.
