Abstract
A loopback dust cap for a fiber optic cable including at least two optical fibers terminated by a connector. The dust cap includes a body having a plurality of cavities including one cavity configured to receive one ferrule of the connector and another cavity configured to receive another ferrule of the connector. The plurality of cavities also defines surfaces in the body that, when the connector engages the dust cap, collimate an optical beam emitted by one optical fiber, redirect the collimated optical beam, and focus the collimated optical beam on another optical fiber. The dust cap is thereby configured to couple optical signals between one optical fiber and another optical fiber of the fiber optic cable.
