The Tektronix TFP2A FiberMaster is an optical time-domain reflectometer (OTDR) for characterizing singlemode and multimode fiber networks. It measures fiber loss, locates faults, and identifies splices and other events by analyzing light pulses reflected from the fiber under test. A high-speed 32-bit processor generates waveforms displayed on a 6.5-inch color CRT with 640 by 480 pixel resolution, enabling precise distance and loss measurements across ranges to 320 km and 100 dB respectively.
