Tektronix OF152 1300 nm Fiber Optic TDR makes quantitative, calibrated loss and distance measurements on multimode fiber at the 1300 nm wavelength. The instrument typically measures breaks through 35 dB, and splices to ±0.1 dB through 13.5 dB of one way cable loss depending on fiber characteristics. Maximum readout range is 60 km, with finely detailed resolution to one meter. The OF152 OTDR allows fast and accurate loss measurement, providing an instant, at-a-glance view of the fiber length on the built-in CRT screen. The OF152 is portable, with a single handle for carrying ease. It operates at virtually any altitude or temperature, from a 12 V vehicle system, an external battery pack or ac. No regulated power source is required. Characteristics. Wavelength: 1300 nm (typical). Displayed Pulse Width Long Pulse: 110m, ± 6 m. Displayed Pulse Width Short Pulse: 20 m, ± 1.2 m. System Pulse Rate: 1.550 kHz ± 1.5 Hz. Optical Output Amplitude: >19 uW Time-average power coupled into test liber (50 um core, 0.20 NA) (Long Pulse mode). Absolute Maximum Optical Output Amplitude: 50 uW time average. Displayed Pulse Risetime: < 10m from - 20 dB point to - 6 dB point. Vertical Scales: 10 dB div and 2 dB div (10 div). dB Scale Accuracy: ± 0.5 dB over any 10 dB div increment from + 20 dB to + 60 dB, relative to bottom of display range. Distance Scales: 5 m/div to 5000 m/div. Display Limits: - 25 m to 60 km from front-panel connector. Distance - LCD Readout Range: 0 km to 60.0 km. Readout esolution: 1 m. Cal Factor Range: 4.9 ns/m to 5.1 ns/m. Cal Factor Accuracy: Within 0.01 ns/m of panel indication at center of scale (5.000). Within 0.02 ns/m of panel indication at scale end points. Measurement Accuracy: ± 0.3%·1 ± the uncertainty in fiber cal factor. Options. Opt. 01 - XY1 Output Module. Opt. 04 - Chart Recorder.
