Rotary mechanical splices between axially aligned optic fibers are seated der axial compression within bays recessed into the body of a holding tray on which a retention lid is fastened in a position to which it is guided by fins on its underside received in grooves formed in the tray body. In such position of the lid on the tray, the lid underside surface covers access formations and the bays between the fins having portions covering fiber slots in the tray through which the optic fibers extend in alignment with their splices.

Shock resistant optic fiber rotary splice holding device

A system for testing a fiber-optic component with infrared radiation is provided. The testing system has a source of infrared radiation, an optic coupler, a detecting circuit, and an analog tape recorder. The optic coupler directs the infrared radiation onto the fiber-optic component. The detection circuit is electrically connected to the tape recorder. The detection circuit has an amplifier, a potentiometer connected in parallel to the amplifier, and a photoelectric transducer connected in series to the amplifier. These components are mounted on a non-conductive board. A power source supplies voltage and is connected to the amplifier. The circuit operates by having the photoelectric transducer sense the infrared radiation emitted from the tested fiber-optic component and convert the radiation into an electrical signal. The amplifier then amplifies the electrical signal to the voltage necessary for driving the tape recorder.
