ABSTRACT OF THE DISCLOSURE A fiber optic interface for combined signal trans- mission and detection is provided. The interface enables transmission in two directions over a single optic fiber and includes a housing having an elongated channel extending therethrough. The housing is comprised of a transparent material. A first optic fiber is secured in one end of the channel with the outermost end of the first optic fiber being aligned with a light source. A second optic fiber is secured in the other end of the channel with the innermost end of the second fiber being disposed adjacent the innermost end of the first fiber. The ends of the fibers are mismatched so that there is a loss of light passed from at least the second fiber to the first fiber during a light transmission from the second to the first fiber. A light sensitive device is secured to the housing and is responsive to light escaping at the junction between the first and the second fiber ends. The mismatching of the fiber ends is accomplished in two ways. The first is the provision of a smaller diameter optic fiber which is connected to the light source than the optic fiber connected to the remote light source. In this way substantially all of the light provided by the light source connected to the first optic fiber is passed to the optic fiber connected to a remote light source. However, in a transmission from the remote light source to the local interface, there is a loss of light about the periphery of the first optic fiber which enables the detection device to pick up the signal.
