ABSTRACT:
Fiber optic devices are tested using an optical switching assembly having two optical switches and optical junctions, each optical junction connects an optical fiber from each of the switches to an external optical fiber lead. Each switch is connected to an optical device, for example a laser or a detector, and selectively establishes an optical path between the corresponding optical device and one of the junctions. Hence, a fiber optic device may be tested by connecting the ends of the fiber optic device to respective junction leads, and selectively switching the optical paths to determine the different optical characteristics of the fiber optic device. Calibration devices may also be connected to the leads of unused junctions to check for calibration accuracy and to detect variation in optical performance over time.
