A fiber optic adapter, also known as a Fiber Optic Connector, is a small device used to Decouple or connect fiber optic cables or fiber optic connectors between two fiber optic lines. A Fiber Adapter allows fiber optic cables to connect to each other alone or to a large network, allowing many devices to communicate at the same time. Fiber Optic Adapters are widely used in the fields of light distribution frame (ODF), fiber optic communication devices, measuring devices and so on.
