A fiber-optic test probe and connector adapter for testing fiber-optic terminations, for example, in fiber optic connector assemblies. A single andmulti-channel connector adapter is provided that is adapted to be attached to the fiber-optic connector to be tested. In one embodiment of the invention, the connector adapter includes an alignment sleeve that enables the terminus of the fiber-optic connector to be tested to be axially aligned with the terminus of the test probe. In order to eliminate air gaps between the respective termini, the fiber-optic test probe and connector adapter are configured to provide axial compression forces between the mating termini in a test position in order to eliminate air gaps therebetween and thus reduce transmission losses. The test probe may be provided with strain relief and anti-bending boot, which prevents radial forces from misaligning the termini. The test probe includes a release sleeve that allows the test probe to be quickly released from its locked position. In an alternate embodiment of the invention, the alignment sleeve may be formed as part of the test probe. A probe calibration adapter, or feed-through adapter, is also provided, which enables two test probes to be coupled together for purposes of calibration. The feed-through adapter is configured to provide precise alignment between the respective termini of the test probe termini, while providing axial compression forces therebetween, similar to the adapter to reduce transmission losses and thus improve performance while providing good repeatability of the test measurements.
