The Fiber Optic Test Set uses a silicon photodetector to measure optical power, which is calibrated at the two most commonly used wavelengths in plastic fiber Ü 660 (red) and 850 (infrared) nanometers. Optical power upon the photodetector is displayed in an easy-to-read 31/2 LCD display that can be set in four different power ranges: 20 µW, 200 µW, 2 mW and 20 mW. The test set includes a 660 nm LED for fiber attenuation measurements, activated by a separate switch with automatic turn-off circuitry to save battery life. The detector and LED are both housed in industry-standard ST® female input connectors. The connectors permit measurements with any plastic fiber in an ST® male connector or connector-less fiber with an outer diameter of 2.5 mm or less. This meter is inexpensive enough for classroom budgets, yet offers the range, features and durability required for industrial application
