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.

An optical distribution system incorporating improved absorbance-based optical fiber sensor incorporating fiber optic couplers, thereby eliminating fiber optic connectors in the system to provide improved efficiency and improved output in the system, the system further incorporating specific thermal stabilizing mechanisms to improve the stability of the system and a specific construction for the photodiode assembly to minimize internal reflection therein.

Optical distribution system incorporating an improved absorbance-based

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.

Beveled angle fiber optic connector

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.

Apparatus for aligning and supporting the optical fibers for an optical

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. The method also holds the respective fiber end faces in suitable connector members in abutting and full engagement at the fiber interface, within a connector enclosure, in a fixed aligned position, in which the vertical aligned position is coincident with the horizontal aligned position for the optical fibers of the connector.

Method for joining optical fibers at the fiber interface of a beveled

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. The transmitting connector connects a transmitting fiber to the mixing fiber to thereby receive a portion of the mixed signal, and connects a comparison fiber to the mixing fiber to transmit a portion of the mixed signal to the signal-measuring component. The tip connector connects the transmitting fiber to the sensor tip fiber to transmit a portion of the mixed signal to the sensor tip, and connects an indicator fiber to the sensor tip to transmit a portion of the resulting indicator signal returned from the sensor tip to the signal-measuring component.
