930XC-20C • 930XC-20M • 930XC-30F • 930XC-30P Section 3. Basic OTDR Information Principle of OTDRs An OTDR (Optical Time Domain Reflectometer) is a measurement instrument for identifying optical fiber transmission features. The OTDR is used to measure the overall attenuation of a fiber optic link and to provide details relating to the position of each event in that link. Events include splices, connectors, bends, and optical components.
930XC-20C • 930XC-20M • 930XC-30F • 930XC-30P When some pulse energy is scattered, reflection events occur. When reflection events occur, a peak is displayed on the trace (Figure 3-1). Measurement Application The 930XC instruments display power relating to the distance of returning signals. This information can be used to identify the main properties of an optical fiber chain. Measurement Contents • • • • • Event location (distance), end, or rupture of optical fiber chain.
930XC-20C • 930XC-20M • 930XC-30F • 930XC-30P The trace of the 930XC displays measurement results in a graphic form. The y-axis represents the power while the x-axis represents the distance (Figure 3-4). Information Window The contents of this window are measurement parameters, events list, marker A/B, and analysis parameters. Figure 3-5a. Measurement Trace Parameters Figure 3-5b.
930XC-20C • 930XC-20M • 930XC-30F • 930XC-30P • Attn.: Attenuation characteristic from one event point to the current event. • Cum.L.: Cumulative loss, calculating from beginning point to the current event. Figure 3-7. Marker A/B Information Marker A/B Information A marker is used to mark and analyze a single event, trace section, and distance. Distance, attenuation, and loss at a marker or between markers will be displayed in marker information (Figure 3-7).
930XC-20C • 930XC-20M • 930XC-30F • 930XC-30P Fiber Information Fiber information includes total attenuation, length, and loss of the tested fiber (Figure 3-8). No.

930XC-20C • 930XC-20M • 930XC-30F • 930XC-30P Pulse Width Configuration The selection of pulse width affects the dynamic range and resolution of the measurement. With a narrow pulse width there will be higher resolution and smaller deadzone; however, the dynamic range will be decreased. A wide pulse width will bring higher dynamic range and measure comparatively longer distance, but resolution and deadzone will be increased. Therefore, users should make the choice between dynamic range and deadzone.
930XC-20C • 930XC-20M • 930XC-30F • 930XC-30P Figure 3-13. Wavelength Configuration Measurement Mode Configuration There are two kinds of measurement mode: averaging and realtime. Under realtime mode the 930XC will undertake realtime measurement for the connector of exterior fiber and refurbish the measured trace. While under realtime mode, press Run/Stop to stop; otherwise it will measure continuously. Under Averaging mode the tool will average the data within the measure time, which is set by the user.
