Information

OF150 820 nm Fiber Optic TDR LCD Readout Resolution to 0.1 dB/1.0 Meter Accurate, Repeatable Measurements Built-In Chart Recorder, Optional Recorder Output Digital Storage Provides Easy to View Waveform and Noise Reduction Two Selectable Pulse Widths Portable — Operates from 12 Volt Vehicle System or Battery Pack Unmatched Range The Tektronix OF150 Time Domain Reflectometer is an optical fiber tester that is capable of measuring loss characteristics, and detecting and locating faults in multimode fibers. The OF150 applies a pulse of energy to the fiber to be tested via the OPTICAL OUTPUT connector. When the pulse is traveling through the fiber, some energy is reflected to the OF150. These reflections are processed, and displayed on the cathode ray tube (crt), where distance and loss measurements can be made using a marker technique. The crt display is a time-plot that is read from left to right. When viewing a typical fiber display, the reflections appear to the right (later in time). The trace starts with the outgoing pulse, and the time difference is converted to distance in the measurement process. The horizontal crt scale is calibrated in distance units from 10 meters to 20,000 meters in a 1-2-5 sequence. Distance is read out on the liquid crystal display (led). Loss measurements are made on the vertical crt scale. These measurements can be displayed in 2 dB or 10 dB per division. The led displays loss when the LOSS READOUT MODE has been selected. The OF150 display is digitally stored. The waveform on the screen changes only when a new “sweep” is started. Two outgoing pulses can be selected: LONG PULSE or SHORT PULSE (for better resolution in some measurements). Two FILTERS use signal averaging to reduce measurement noise. Typical applications include: splice measurement through a one-way cable loss of up to 21.5 dB to within ±0.1 dB; detection of fiber ends, (four percent Fresnel reflection) through a one-way cable loss of up to 42.5 dB; and measuring distance to discontinuities (such as splices, Fiber faults and ends) to 19.9 km, with one meter resolution.
