Abstract: An optical distribution system incorporating an improved luminescent based optical fiber sensor incorporating a signal generating component for generating a first optical signal, a signal separating component for delivering said first optical signal to the sensor, delivering said second returned optical signal to an associated signal detector, and including signal interference means to separate said first and second signals and minimize cross-talk therebetween. A sensor optical fiber connects a sensor tip to the signal separating component. The signal detector receives a returned signal from the signal separating component and transmits it to a signal-measuring component of the distribution system.

Abstract: A fiber optic connector in which first and second optical fibers are aligned at a fiber interface of the connector. The first optical fiber has a beveled angle end face, and the second optical fiber has a complementary beveled angle end face. Abutting connector members are joined in a connector enclosure which enables the respective fiber end faces to abut at an angle at the fiber interface. The respective fiber end faces are joined at a vertical aligned position for the connector, also at a horizontal aligned position for the connector. Suitable alignment means provided on the connector members enable alignment of the fiber end faces at the fiber interface. In a fixed aligned position of the assembled connector, the respective fiber end faces are held in abutting and full engagement at the fiber interface, in which the vertical aligned position of the optical fibers in the connector is coincident with the horizontal aligned position thereof.

Abstract: Support apparatus for a fiber optic cable assembly which includes optical fibers having end faces, high tensile strength fibers contiguous with and generally parallel to the optical fibers, and one or more electrical conductors. A main body portion of the apparatus supports the fiber optic cable assembly and includes a central channel and posts therein, for first supporting the cable assembly, then separating the optical fibers from the high tensile strength elements and the electrical conductor, and then aligning the optical fibers on the apparatus so as to precisely position the respective end faces thereof at an outer end of the main body portion of the apparatus.

Abstract: A method for aligning first and second optical fibers of a fiber optic connector at a fiber interface wherein the first optical fiber has a beveled angle end face and the second optical fiber a complementary beveled angle end face, the method including the step of abutting the respective fiber end faces at an angle at the interface, cooperatively engaging a vertical reference surface associated with the first optical fiber with a vertical reference nodule associated with the second optical fiber to align the respective fiber end faces at a vertical aligned position for the connector. Respective horizontal reference surfaces associated with the first optical fiber are also cooperatively engaged with a horizontal reference node and a compressible crush rib associated with the second optical fiber to align the respective fiber end faces at a horizontal aligned position for the connector.

Abstract: A device for distributing signals within a sensor system used for monitoring the presence of a specific analyte in a composition by means of an analyte-sensitive indicator molecule is disclosed. The sensor system includes a signal-generating component, a single-fiber sensor tip that houses the indicator molecule and a signal-measuring component. In one embodiment, the signal-generating component generates a first optical signal of a wavelength that is sensitive to the indicator molecule, and a second optical signal of a wavelength that is predictably altered by the indicator molecule. The distribution system includes lengths of optical fiber, a dividing connector, a mixing connector, a transmitting connector and a tip connector. The dividing connector connects at least three intermediate fibers to the signal-generating component to receive intermediate signals. The mixing connector connects a mixing fiber to the intermediate fibers to receive the intermediate signals and blend them into a single mixed signal.
