The optical Fiber Adapter is the connection part in the active optical connectors. We offers the full range of adapters including FC, SC, ST, LC, E2000, MTRJ and hybrid adapters. These adapters are widely used in ODF, optic-fiber communications equipment, optical fiber instruments etc.
The combination of a ceramic / phosphor bronze alignment sleeves and a precision moulded polymer housing provides consistent long-term mechanical and optical performance.
KCO-SCD-CAP-B Dusty Cap For SC Duplex Adapter is specical design for SC Duplex adapter only. It can protect the ceramic sleeve from outside dusty. Use high quality plastic to make, it has long life time and can fit with all type of SC duplex adapter.
Normally, the color is black color, we can sastify to make it in other color such as non-color, white, beige, pink, blue, ....
