Abstract
A fiber optic transceiver module having built-in test capability is packaged in a housing to meet small-form-factor (SFF) requirements. The module has a first optical fiber having an angled end that defines an acute angle relative to a longitudinal axis of the first optical fiber. A second optical fiber also has an angled end that defines an acute angle relative to the longitudinal axis of the second optical fiber. The first optical fiber and the second optical fiber are aligned with one another. An optical source emits an optical signal propagated along the first optical fiber in which a portion of the optical signal is received at the second optical fiber and is propagated along the second optical fiber. An optical detector receives a return optical signal transmitted through the angled end of the second optical fiber in response to reflection from a discontinuity in the optical path of the second optical fiber.
