An apparatus for testing optical components. The apparatus includes a component cavity. The component cavity includes a package portion generally including fit tolerances but otherwise including a similar size and shape of an optical component to be tested. The component cavity further includes an electrical interface portion that can hold electrical interface leads of the optical component. The apparatus further includes an optical fiber interface optically connected to the cavity. The optical fiber interface mates with an optical fiber. The optical fiber is connected optically to the optical component being tested.
