Plastic Fiber Optic Phototransistor

The Plastic Fiber Optic Phototransistor is the photodiode in our family of low-cost, medium-frequency, short-distance fiber optic LEDs and detectors. Each device consists of a polycarbonate (PC) housing which retains the internal active element such as an LED or photodetector subcomponent, and a cinch nut to hold the fiber in place. The PC assembly optimizes coupling between the active element and jacketed 1000 µm plastic fiber. Working with this family of fiber optics requires no special tools or training. Only a sharp knife or razor blade is needed to terminate the plastic fiber. When the fiber is inserted in the LED or detector housing, the cinch nut is tightened. Thereafter, the fiber can be removed simply by loosening the nut.
