A fiber optic connector primarily serves the purpose of joining two fiber optic cables together. This connectivity allows light signals to pass smoothly from one cable to another, maintaining the integrity of the data being transmitted. The structure of a fiber optic connector is designed to align and mate the fibers precisely to minimize loss of signal and maximize performance.

In addition to enabling connections, fiber optic connectors often include features that might help reduce issues like back reflection or signal loss, but their fundamental role is in providing a physical link between fiber optic cables. This makes them indispensable in network setups, repair tasks, and when extending fiber optic systems.

Other functions may enhance performance, such as reducing back reflection, but these are secondary to the connector's main duty of creating a secure and efficient connection between cables.
