50PCS FC D-Type Fiber Optic Adapter, FC Square Simplex Fiber Optic Coupler, FC-FC Optical Fiber Connector Adapter, Low Insertion Loss Coupler for FTTH, Optical Test Equipment, Optical Communication Ne

This pack contains 50 pieces FC D-Type fiber optic adapters, also known as FC fiber couplers. The adapter serves to interconnect two FC fiber connectors to extend optical fiber links in communication systems.

Equipped with high-precision ceramic alignment sleeve, it minimizes signal attenuation and ensures consistent optical transmission performance. The D-shaped square housing features compact dimensions, perfectly fitting limited space inside communication cabinets and distribution boxes.

Robust housing construction offers great wear resistance for frequent assembly and disassembly. Widely applied in FTTH cabling, fiber testing equipment, optical transmission devices, data center wiring and various optical communication engineering projects.

Operating Notice: Handle fiber connectors gently to prevent scratches on the ceramic end face. Keep the internal sleeve clean to avoid dust contamination which may affect transmission effect.
