Description
Product Description
- Aligns fiber cores at the ends of fiber patch cords with mating sleeves.
- Used for FC/PC-to-SMA and SMA-to-SMA fiber conversion.
- Built-in split ceramic mating sleeve for low-loss coupling between ferrules.
- 2 mm wide-key FC/PC connector.
- SMA905 connector.
The main function of the fiber sleeve adapter is to ensure accurate alignment of fiber cores at the ends of patch cords.

Technical Description
- The primary role of the fiber sleeve adapter is to ensure core alignment at the ends of fiber patch cords. It is used to match singlemode (SM) or multimode (MM) fibers with FC/PC connectors to MM fibers with SMA connectors, maintaining physical contact between end faces for stable and efficient optical signal transmission.

- It reduces optical loss and signal attenuation through precise core matching and alignment, and is commonly used to connect different fiber connector types. We offer FC/PC-to-SMA and SMA-to-SMA adapters.
