A fiber optic adapter, sometimes also called a coupler, is a small device designed to terminate or link the fiber optic cables or fiber optic connectors between two fiber optic lines.
The CS™ adapter can link two CS™ connectors precisely, allowing the light sources to be transmitted at most and lower the loss as much as possible. And this adapter has a smaller size and higher density when compared to an LC duplex adapter. At the same time, fiber optic adapters have the merits of low insertion loss, good interchangeability and reproducibility.
